A scientist is a person who researches to advance knowledge in an area of the natural sciences .
148-412: In classical antiquity , there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy , a precursor of natural science . Though Thales ( c. 624–545 BC) was arguably the first scientist for describing how cosmic events may be seen as natural, not necessarily caused by gods, it was not until the 19th century that
296-455: A kite came to his cradle and opened his mouth with its tail; commentators still debate whether the anecdote was an actual memory or a fantasy. In the mid-1460s, Leonardo's family moved to Florence, which at the time was the centre of Christian Humanist thought and culture. Around the age of 14, he became a garzone (studio boy) in the workshop of Andrea del Verrocchio , who was the leading Florentine painter and sculptor of his time. This
444-434: A res publica as long as it continued to use Latin as its official language. Rome acquired imperial character de facto from the 130s BC with the acquisition of Cisalpine Gaul , Illyria , Greece and Hispania , and definitely with the addition of Iudaea , Asia Minor and Gaul during the 1st century BC. At the time of the empire's maximal extension during the reign of Trajan (AD 117), Rome controlled
592-416: A thesis (or dissertation) during an oral examination . To aid them in this endeavor, graduate students often work under the guidance of a mentor , usually a senior scientist, which may continue after the completion of their doctorates whereby they work as postdoctoral researchers . After the completion of their training, many scientists pursue careers in a variety of work settings and conditions. In 2017,
740-479: A brass hook that was holding the leg in place. The leg twitched. Further experiments confirmed this effect, and Galvani was convinced that he was seeing the effects of what he called animal electricity, the life force within the muscles of the frog. At the University of Pavia , Galvani's colleague Alessandro Volta was able to reproduce the results, but was sceptical of Galvani's explanation. Lazzaro Spallanzani
888-461: A commission from the Monks of San Donato a Scopeto. It is a complex composition, of about 250 x 250 centimetres. Leonardo did numerous drawings and preparatory studies, including a detailed one in linear perspective of the ruined classical architecture that forms part of the background. In 1482 Leonardo went to Milan at the behest of Lorenzo de' Medici in order to win favour with Ludovico il Moro, and
1036-622: A common term in the late 19th century in the United States and around the turn of the 20th century in Great Britain . By the twentieth century, the modern notion of science as a special brand of information about the world, practiced by a distinct group and pursued through a unique method, was essentially in place. Marie Curie became the first woman to win the Nobel Prize and the first person to win it twice. Her efforts led to
1184-537: A cultivator of physics, I have called him a Physicist . We need very much a name to describe a cultivator of science in general. I should incline to call him a Scientist . Thus we might say, that as an Artist is a Musician, Painter, or Poet, a Scientist is a Mathematician, Physicist, or Naturalist. He also proposed the term physicist at the same time, as a counterpart to the French word physicien . Neither term gained wide acceptance until decades later; scientist became
1332-612: A finger in her bible to mark the place and raises her hand in a formal gesture of greeting or surprise. This calm young woman appears to accept her role as the Mother of God , not with resignation but with confidence. In this painting, the young Leonardo presents the humanist face of the Virgin Mary, recognising humanity's role in God's incarnation. In the 1480s, Leonardo received two very important commissions and commenced another work that
1480-469: A frequent namesake and subject in culture . Leonardo is identified as one of the greatest painters in the history of Western art and is often credited as the founder of the High Renaissance. Despite having many lost works and fewer than 25 attributed major works – including numerous unfinished works – he created some of the most influential paintings in
1628-537: A fur-lined cloak. On 12 August 1519, Leonardo's remains were interred in the Collegiate Church of Saint Florentin at the Château d'Amboise. Some 20 years after Leonardo's death, Francis was reported by the goldsmith and sculptor Benvenuto Cellini as saying: "There had never been another man born in the world who knew as much as Leonardo, not so much about painting, sculpture and architecture, as that he
SECTION 10
#17327648516911776-454: A hundred years it was described by one viewer as "completely ruined." Leonardo, instead of using the reliable technique of fresco, had used tempera over a ground that was mainly gesso , resulting in a surface subject to mould and to flaking. Despite this, the painting remains one of the most reproduced works of art; countless copies have been made in various mediums. Toward the end of this period, in 1498 Leonardo's trompe-l'œil decoration of
1924-665: A letter which described the diverse things that he could achieve in the fields of engineering and weapon design, and mentioned that he could paint. He brought with him a silver string instrument – either a lute or lyre – in the form of a horse's head. With Alberti, Leonardo visited the home of the Medici and through them came to know the older Humanist philosophers of whom Marsiglio Ficino , proponent of Neoplatonism ; Cristoforo Landino , writer of commentaries on Classical writings, and John Argyropoulos , teacher of Greek and translator of Aristotle were
2072-646: A local oral tradition recorded by the historian Emanuele Repetti , is that he was born in Anchiano , a country hamlet that would have offered sufficient privacy for the illegitimate birth, though it is still possible he was born in a house in Florence that Ser Piero almost certainly had. Leonardo's parents both married separately the year after his birth. Caterina – who later appears in Leonardo's notes as only "Caterina" or "Catelina" –
2220-408: A mere 7 percent in 1970 to 34 percent in 1985 and in engineering alone the numbers of bachelor's degrees awarded to women rose from only 385 in 1975 to more than 11000 in 1985. Classical antiquity Classical antiquity , also known as the classical era , classical period , classical age , or simply antiquity , is the period of cultural European history between the 8th century BC and
2368-401: A painter, draughtsman, engineer, scientist, theorist, sculptor, and architect. While his fame initially rested on his achievements as a painter, he has also become known for his notebooks , in which he made drawings and notes on a variety of subjects, including anatomy, astronomy, botany, cartography, painting, and palaeontology . Leonardo is widely regarded to have been a genius who epitomised
2516-594: A painting commission of unknown subject matter, but cancelled it when the artist set about developing a new kind of varnish . Leonardo became ill, in what may have been the first of multiple strokes leading to his death. He practised botany in the Vatican Gardens , and was commissioned to make plans for the Pope's proposed draining of the Pontine Marshes . He also dissected cadavers , making notes for
2664-456: A posthumous inventory of his belongings; it was assessed at 505 lire, an exceptionally high valuation for a small panel portrait. Despite the thousands of pages Leonardo left in notebooks and manuscripts, he scarcely made reference to his personal life. Within Leonardo's lifetime, his extraordinary powers of invention, his "great physical beauty" and "infinite grace," as described by Vasari , as well as all other aspects of his life, attracted
2812-734: A priest to make his confession and to receive the Holy Sacrament . Vasari also records that the King held Leonardo's head in his arms as he died, although this story may be legend rather than fact. In accordance with his will, sixty beggars carrying tapers followed Leonardo's casket. Melzi was the principal heir and executor, receiving, as well as money, Leonardo's paintings, tools, library and personal effects. Leonardo's other long-time pupil and companion, Salaì, and his servant Baptista de Vilanis, each received half of Leonardo's vineyards . His brothers received land, and his serving woman received
2960-586: A profession, the scientist of today is widely recognized. However, there is no formal process to determine who is a scientist and who is not a scientist. Anyone can be a scientist in some sense. Some professions have legal requirements for their practice (e.g. licensure ) and some scientists are independent scientists meaning that they practice science on their own, but to practice science there are no known licensure requirements. In modern times, many professional scientists are trained in an academic setting (e.g., universities and research institutes ), mostly at
3108-761: A result of the crisis of the third century . During Late antiquity Christianity became increasingly popular, finally ousting the Roman imperial cult with the Theodosian decrees of 393. Successive invasions of Germanic tribes finalized the weakening of the Western Roman Empire during the 5th century, while the Eastern Roman Empire persisted throughout the Middle Ages , in a state called Romania by its citizens, and designated

#17327648516913256-409: A result, scientific researchers often accept lower average salaries when compared with many other professions which require a similar amount of training and qualification. Scientists include experimentalists who mainly perform experiments to test hypotheses, and theoreticians who mainly develop models to explain existing data and predict new results. There is a continuum between two activities and
3404-410: A rich flowing garment, raised wings and bearing a lily. Although previously attributed to Ghirlandaio, the larger work is now generally attributed to Leonardo. In the smaller painting, Mary averts her eyes and folds her hands in a gesture that symbolised submission to God's will. Mary is not submissive, however, in the larger piece. The girl, interrupted in her reading by this unexpected messenger, puts
3552-643: A rocky landscape rather than architectural details. The painting was eventually finished; in fact, two versions of the painting were finished: one remained at the chapel of the Confraternity, while Leonardo took the other to France. The Brothers did not get their painting, however, nor the de Predis their payment, until the next century. Leonardo's most remarkable portrait of this period is the Lady with an Ermine , presumed to be Cecilia Gallerani ( c. 1483–1490 ), lover of Ludovico Sforza. The painting
3700-643: A series of conflicts of the 4th and 3rd centuries, the Samnite Wars , Latin War , and Pyrrhic War . Roman victory in the Punic Wars and Macedonian Wars established Rome as a super-regional power by the 2nd century BC, followed by the acquisition of Greece and Asia Minor . This tremendous increase of power was accompanied by economic instability and social unrest, resulting in the Catiline conspiracy ,
3848-492: A successful career. Despite his family history, Leonardo only received a basic and informal education in (vernacular) writing, reading, and mathematics; possibly because his artistic talents were recognised early, so his family decided to focus their attention there. Later in life, Leonardo recorded his earliest memory, now in the Codex Atlanticus . While writing on the flight of birds, he recalled as an infant when
3996-450: A time. This was beyond the comprehension of the prior of the convent, who hounded him until Leonardo asked Ludovico to intervene. Vasari describes how Leonardo, troubled over his ability to adequately depict the faces of Christ and the traitor Judas , told the duke that he might be obliged to use the prior as his model. The painting was acclaimed as a masterpiece of design and characterisation, but it deteriorated rapidly, so that within
4144-406: A town plan of Imola in order to win his patronage. Upon seeing it, Cesare hired Leonardo as his chief military engineer and architect. Later in the year, Leonardo produced another map for his patron, one of Chiana Valley , Tuscany, so as to give his patron a better overlay of the land and greater strategic position. He created this map in conjunction with his other project of constructing a dam from
4292-460: A treatise on vocal cords ; these he gave to an official in hopes of regaining the Pope's favour, but he was unsuccessful. In October 1515, King Francis I of France recaptured Milan. On 21 March 1516 Antonio Maria Pallavicini, the French ambassador to the Holy See , received a letter sent from Lyon a week previously by the royal advisor Guillaume Gouffier, seigneur de Bonnivet , containing
4440-401: A very young man: a local peasant made himself a round buckler shield and requested that Ser Piero have it painted for him. Leonardo, inspired by the story of Medusa , responded with a painting of a monster spitting fire that was so terrifying that his father bought a different shield to give to the peasant and sold Leonardo's to a Florentine art dealer for 100 ducats , who in turn sold it to
4588-455: A widely regarded prestigious award, is awarded annually to those who have achieved scientific advances in the fields of medicine , physics , and chemistry . Some scientists have a desire to apply scientific knowledge for the benefit of people's health, the nations, the world, nature, or industries (academic scientist and industrial scientist ). Scientists tend to be less motivated by direct financial reward for their work than other careers. As

The number of scientists is vastly different from country to country. For instance, there are only four full-time scientists per 10,000 workers in India, while this number is 79 for the United Kingdom, and 85 for

He made important contributions to the experimental study of bodily functions and animal reproduction. Francesco Redi discovered that microorganisms can cause disease . Until the late 19th or early 20th century, scientists were still referred to as " natural philosophers " or "men of science". English philosopher and historian of science William Whewell coined

Since that date much has been written about his presumed homosexuality and its role in his art, particularly in the androgyny and eroticism manifested in Saint John the Baptist and Bacchus and more explicitly in a number of erotic drawings. Despite
5328-482: Is the only extant example of Leonardo's sculpture. Leonardo was otherwise free to pursue his scientific interests. Many of Leonardo's most prominent pupils either knew or worked with him in Milan, including Bernardino Luini , Giovanni Antonio Boltraffio , and Marco d'Oggiono . In 1507, Leonardo was in Florence sorting out a dispute with his brothers over the estate of his father, who had died in 1504. By 1508, Leonardo
5476-573: Is usually identified as the Caterina Buti del Vacca, who married the local artisan Antonio di Piero Buti del Vacca, nicknamed L'Accattabriga , 'the quarrelsome one'. Ser Piero married Albiera Amadori – having been betrothed to her the previous year – and after her death in 1464, went on to have three subsequent marriages. From all the marriages, Leonardo eventually had 16 half-siblings (of whom 11 survived infancy) who were much younger than he (the last

Knowledge of plants and animals was broadly the province of physicians. Science in medieval Islam generated some new modes of developing natural knowledge, although still within the bounds of existing social roles such as philosopher and mathematician. Many proto-scientists from

Hellenistic philosophy was succeeded by continued development of Platonism and Epicureanism , with Neoplatonism in due course influencing the theology of the Christian Church Fathers . Many writers have attempted to name a specific date for the symbolic "end" of antiquity, with the most prominent dates being the deposing of the last Western Roman Emperor in 476,

The Eastern Roman empire's capital city Constantinople remained the only unconquered large urban site of the original Roman empire, as well as being the largest city in Europe. Yet many classical books, sculptures, and technologies survived there along with classical Roman cuisine and scholarly traditions, well into the Middle Ages, when much of it was "rediscovered" by visiting Western crusaders. Indeed,

The political idea of an Emperor in the West to match
6364-584: The Duke of Milan . By 1472, at the age of 20, Leonardo qualified as a master in the Guild of Saint Luke , the guild of artists and doctors of medicine, but even after his father set him up in his own workshop, his attachment to Verrocchio was such that he continued to collaborate and live with him. Leonardo's earliest known dated work is a 1473 pen-and-ink drawing of the Arno valley (see below). According to Vasari,
6512-485: The Islamic Golden Age are considered polymaths , in part because of the lack of anything corresponding to modern scientific disciplines . Many of these early polymaths were also religious priests and theologians : for example, Alhazen and al-Biruni were mutakallimiin ; the physician Avicenna was a hafiz ; the physician Ibn al-Nafis was a hafiz, muhaddith and ulema ; the botanist Otto Brunfels
6660-680: The Mona Lisa , the Last Supper , and the Virgin of the Rocks . Leonardo first gained attention for his work on the Baptism of Christ , painted in conjunction with Verrocchio. Two other paintings appear to date from his time at Verrocchio's workshop, both of which are Annunciations . One is small, 59 centimetres (23 in) long and 14 cm (5.5 in) high. It is a " predella " to go at
6808-578: The Muslim conquests of the 7th century finalized the irreversible loss of all the largest Eastern Roman imperial cities besides the capital itself. The emperor Heraclius in Constantinople , who reigned during this period, conducted his court in Greek, not Latin, though Greek had always been an administrative language of the eastern Roman regions. Eastern-Western associations weakened with the ending of
6956-588: The Renaissance . Some of his smaller inventions, however, entered the world of manufacturing unheralded, such as an automated bobbin winder and a machine for testing the tensile strength of wire. He made substantial discoveries in anatomy , civil engineering, hydrodynamics , geology, optics , and tribology , but he did not publish his findings and they had little to no direct influence on subsequent science. Leonardo da Vinci, properly named Leonardo di ser Piero da Vinci ("Leonardo, son of ser Piero from Vinci"),

Born out of wedlock to a successful notary and a lower-class woman in, or near, Vinci , he was educated in Florence by the Italian painter and sculptor Andrea del Verrocchio . He began his career in the city, but then spent much time in

In 1505, Leonardo was commissioned to paint The Battle of Anghiari in the Salone dei Cinquecento (Hall of the Five Hundred) in the Palazzo Vecchio , Florence. Leonardo devised a dynamic composition depicting four men riding raging war horses engaged in a battle for possession of a standard, at the Battle of Anghiari in 1440. Michelangelo

#17327648516917696-788: The Scientific Revolution that began in 16th century as the period when science in a recognizably modern form developed. It was not until the 19th century that sufficient socioeconomic changes had occurred for scientists to emerge as a major profession. Knowledge about nature in classical antiquity was pursued by many kinds of scholars. Greek contributions to science—including works of geometry and mathematical astronomy, early accounts of biological processes and catalogs of plants and animals, and theories of knowledge and learning—were produced by philosophers and physicians , as well as practitioners of various trades. These roles, and their associations with scientific knowledge, spread with
7844-780: The Social War and the First Triumvirate , and finally the transformation to the Roman Empire during the latter half of the 1st century BC. The precise end of the Republic is disputed by modern historians; Roman citizens of the time did not recognize that the Republic had ceased to exist. The early Julio-Claudian Emperors maintained that the res publica still existed, albeit protected by their extraordinary powers, and would eventually return to its earlier Republican form. The Roman state continued to term itself

The Last Supper is the most reproduced religious painting of all time and his Vitruvian Man drawing is also regarded as a cultural icon. In 2017, Salvator Mundi , attributed in whole or part to Leonardo, was sold at auction for US$ 450.3 million , setting a new record for

The philosophy of St. Thomas Aquinas was derived largely from that of Aristotle , despite the intervening change in religion from Hellenic Polytheism to Christianity . Greek and Roman authorities such as Hippocrates and Galen formed the basis of the practice of medicine even longer than Greek thought prevailed in philosophy. In the French theater , playwrights such as Molière and Racine wrote plays on mythological or classical historical subjects and subjected them to

Revered for his technological ingenuity , he conceptualised flying machines, a type of armoured fighting vehicle , concentrated solar power, a ratio machine that could be used in an adding machine , and the double hull . Relatively few of his designs were constructed or were even feasible during his lifetime, as the modern scientific approaches to metallurgy and engineering were only in their infancy during

Greek colonisation refers to the expansion of Archaic Greeks , particularly during the 8th–6th centuries BC , across the Mediterranean Sea and the Black Sea . The Etruscans had established political control in the region by the late 7th-century BC, forming the aristocratic and monarchial elite. The Etruscans apparently lost power in
8732-507: The 1490s Leonardo had already been described as a "Divine" painter. Among the qualities that make Leonardo's work unique are his innovative techniques for laying on the paint; his detailed knowledge of anatomy, light, botany and geology; his interest in physiognomy and the way humans register emotion in expression and gesture; his innovative use of the human form in figurative composition; and his use of subtle gradation of tone. All these qualities come together in his most famous painted works,

Genres like epic poetry, pastoral verse, and the frequent use of characters and themes from Greek mythology affected Western literature greatly. In architecture, there have been several Greek Revivals , which seem more inspired in retrospect by Roman architecture than Greek. Washington, DC has many large marble buildings with façades made to look like Greek temples , with columns constructed in

In Cesena in 1502, Leonardo entered the service of Cesare Borgia , the son of Pope Alexander VI , acting as a military architect and engineer and travelling throughout Italy with his patron. Leonardo created a map of Cesare Borgia's stronghold,

The project became a trompe-l'œil decoration that made the great hall appear to be a pergola created by the interwoven limbs of sixteen mulberry trees, whose canopy included an intricate labyrinth of leaves and knots on the ceiling. When Ludovico Sforza was overthrown by France in 1500, Leonardo fled Milan for Venice , accompanied by his assistant Salaì and friend,
10360-420: The Eastern Roman capital ( first in 674–78 and then in 717–18 ) severed the economic, cultural, and political links that had traditionally united the classical cultures around the Mediterranean, ending antiquity (see Pirenne Thesis ). The original Roman Senate continued to express decrees into the late 6th century, and the last Eastern Roman emperor to use Latin as the language of his court in Constantinople
10508-421: The Emperor in the East continued after the Western Roman Empire's collapse; it was revived by the coronation of Charlemagne in 800; the self-described Holy Roman Empire ruled central Europe until 1806. The Renaissance idea that the classical Roman virtues had been lost as a result of medievalism was especially powerful in European politics of the 18th and 19th centuries. Reverence for Roman republicanism

Pallavicini was also asked to reassure Leonardo that he would be well received at court, both by the King and by his mother, Louise of Savoy . Leonardo entered Francis's service later that year, and was given the use of the manor house Clos Lucé near

10952-523: The Greeks. Fathers had great power over their children, and husbands over their wives. In fact, the word family, familia in Latin, actually referred to those who were subject to the authority of a male head of household. This included non-related members such as slaves and servants. By marriage, both men and women shared property. Divorce was allowed first during the first century BC and could be done by either man or woman. The Roman Empire began to weaken as

He also made a mechanical lion, which during a pageant walked towards the King and – upon being struck by a wand – opened its chest to reveal a cluster of lilies. Leonardo was accompanied during this time by his friend and apprentice Francesco Melzi, and
11396-521: The Senate and had Superbus and the monarchy expelled from Rome in 510 BC. After Superbus' expulsion, the Senate in 509 BC voted to never again allow the rule of a king and reformed Rome into a republican government . The classical period of Ancient Greece corresponds to most of the 5th and 4th centuries BC, in particular, from the end of the Athenian tyranny in 510 BC to the death of Alexander
11544-550: The United States. According to the National Science Foundation , 4.7 million people with science degrees worked in the United States in 2015, across all disciplines and employment sectors. The figure included twice as many men as women. Of that total, 17% worked in academia, that is, at universities and undergraduate institutions, and men held 53% of those positions. 5% of scientists worked for
11692-569: The area by the late 6th-century BC, and at this time, the Italic tribes reinvented their government by creating republics , with greater restraints on the ability of individual rulers to exercise power. According to legend, Rome was founded on 21 April 753 BC by twin descendants of the Trojan prince Aeneas , Romulus and Remus . As the city was bereft of women, legend says that the Latins invited
11840-414: The art of combining complex figure compositions with detailed architectural backgrounds. Piero della Francesca had made a detailed study of perspective , and was the first painter to make a scientific study of light. These studies and Leon Battista Alberti 's treatise De pictura were to have a profound effect on younger artists and in particular on Leonardo's own observations and artworks. Much of
11988-643: The artistic skills of drawing, painting, sculpting, and modelling. Leonardo was a contemporary of Botticelli, Ghirlandaio and Perugino, who were all slightly older than he was. He would have met them at the workshop of Verrocchio or at the Platonic Academy of the Medici . Florence was ornamented by the works of artists such as Donatello's contemporaries Masaccio , whose figurative frescoes were imbued with realism and emotion, and Ghiberti , whose Gates of Paradise , gleaming with gold leaf , displayed
12136-475: The base of a larger composition, a painting by Lorenzo di Credi from which it has become separated. The other is a much larger work, 217 cm (85 in) long. In both Annunciations, Leonardo used a formal arrangement, like two well-known pictures by Fra Angelico of the same subject, of the Virgin Mary sitting or kneeling to the right of the picture, approached from the left by an angel in profile, with
12284-516: The closing of the last Platonic Academy in Athens by the Eastern Roman emperor Justinian I in 529, and the conquest of much of the Mediterranean by the new Muslim faith from 634 to 718. These Muslim conquests, of Syria (637), Egypt (639), Cyprus (654), North Africa (665), Hispania (718), Southern Gaul (720), Crete (820), and Sicily (827), Malta (870), as well as the sieges of
12432-690: The creation of a new Greek state in 1832. After the capture of Constantinople in 1453, the Russian Czars (a title derived from Caesar) claimed the Byzantine legacy as the champion of Orthodoxy ; Moscow was described as the " Third Rome ", and the Czars ruled as divinely appointed Emperors into the 20th century. Despite the fact that the Western Roman secular authority disappeared entirely in Europe, it still left traces. The Papacy and
12580-663: The cultures of Persia , the Kingdom of Israel and Kingdom of Judah , Central Asia and Egypt . Significant advances were made in the sciences ( geography , astronomy , mathematics , etc.), notably with the followers of Aristotle ( Aristotelianism ). The Hellenistic period ended with the increase of the Roman Republic to a super-regional power during the 2nd century BC and the Roman conquest of Greece in 146 BC. The Republican period of Ancient Rome began with
12728-523: The curiosity of others. One such aspect was his love for animals, likely including vegetarianism and according to Vasari, a habit of purchasing caged birds and releasing them. Leonardo had many friends who are now notable either in their fields or for their historical significance, including mathematician Luca Pacioli , with whom he collaborated on the book Divina proportione in the 1490s. Leonardo appears to have had no close relationships with women except for his friendship with Cecilia Gallerani and
12876-618: The development of nuclear energy and Radiotherapy for the treatment of cancer. In 1922, she was appointed a member of the International Commission on Intellectual Co-operation by the Council of the League of Nations. She campaigned for scientist's right to patent their discoveries and inventions. She also campaigned for free access to international scientific literature and for internationally recognized scientific symbols. As
13024-411: The development of science) have had widely different places in society, and the social norms , ethical values , and epistemic virtues associated with scientists—and expected of them—have changed over time as well. Accordingly, many different historical figures can be identified as early scientists, depending on which characteristics of modern science are taken to be essential. Some historians point to
13172-488: The disappearance of imperial authority in the west. This tendency reached its maximum when Charlemagne was crowned "Roman Emperor" in the year 800, an act which resulted in the formation of the Holy Roman Empire . The notion that an emperor is a monarch who outranks a king dates from this period. In this political ideal, there would always be a Roman Empire, a state the jurisdiction of which extended through
13320-553: The division between them is not clear-cut, with many scientists performing both tasks. Those considering science as a career often look to the frontiers. These include cosmology and biology , especially molecular biology and the human genome project. Other areas of active research include the exploration of matter at the scale of elementary particles as described by high-energy physics , and materials science , which seeks to discover and design new materials. Others choose to study brain function and neurotransmitters , which
13468-667: The dominance of Athens in the Delian League , which resulted in conflict with Sparta and the Peloponnesian League , resulting in the Peloponnesian War (431–404 BC), ending with a Spartan victory. Greece began the 4th century with Spartan hegemony , but by 395 BC the Spartan rulers dismissed Lysander from office, and Sparta lost its naval supremacy. Athens , Argos , Thebes and Corinth ,
13616-489: The earliest recorded Epic Greek poetry of Homer (8th–7th-century BC) and ends with the end of the Western Roman Empire in 476 AD. Such a wide span of history and territory covers many disparate cultures and periods. Classical antiquity may also refer to an idealized vision among later people of what was, in Edgar Allan Poe 's words, "the glory that was Greece, and the grandeur that was Rome". The culture of
13764-520: The entire Mediterranean as well as Gaul, parts of Germania and Britannia , the Balkans , Dacia , Asia Minor, the Caucasus , and Mesopotamia . Culturally, the Roman Empire was significantly Hellenized , but also incorporated syncretic "eastern" traditions, such as Mithraism , Gnosticism , and most notably Christianity . Classical Rome had vast differences within their family life compared to
13912-649: The entire civilized western world. That model continued to exist in Constantinople for the entirety of the Middle Ages, where the Byzantine Emperor was considered the sovereign of the entire Christian world. The Patriarch of Constantinople was the Empire's highest-ranked cleric, but even he was subordinate to the emperor, who was "God's Vicegerent on Earth". The Greek-speaking Byzantines and their descendants continued to call themselves " Romioi " until
14060-464: The federal government, and about 3.5% were self-employed. Of the latter two groups, two-thirds were men. 59% of scientists in the United States were employed in industry or business, and another 6% worked in non-profit positions. Scientist and engineering statistics are usually intertwined, but they indicate that women enter the field far less than men, though this gap is narrowing. The number of science and engineering doctorates awarded to women rose from
14208-509: The foreground sprawls his symbol, a great lion whose body and tail make a double spiral across the base of the picture space. The other remarkable feature is the sketchy landscape of craggy rocks against which the figure is silhouetted. The daring display of figure composition, the landscape elements and personal drama also appear in the great unfinished masterpiece, the Adoration of the Magi ,
14356-528: The foremost. Also associated with the Platonic Academy of the Medici was Leonardo's contemporary, the brilliant young poet and philosopher Pico della Mirandola . In 1482, Leonardo was sent as an ambassador by Lorenzo de' Medici to Ludovico il Moro , who ruled Milan between 1479 and 1499. Leonardo worked in Milan from 1482 until 1499. He was commissioned to paint the Virgin of the Rocks for
14504-540: The fringes of India . The classical Greek period conventionally ends at the death of Alexander in 323 BC and the fragmentation of his empire, which was at this time divided among the Diadochi . Greece began the Hellenistic period with the increasing power of Macedon and the conquests of Alexander the Great . Greek became the lingua franca far beyond Greece itself, and Hellenistic culture interacted with
14652-530: The household of his paternal grandfather, Antonio da Vinci, but it is possible that he spent the years before then in the care of his mother in Vinci, either Anchiano or Campo Zeppi in the parish of San Pantaleone. He is thought to have been close to his uncle, Francesco da Vinci, but his father was probably in Florence most of the time. Ser Piero, who was the descendant of a long line of notaries, established an official residence in Florence by at least 1469 and had
14800-431: The ideas behind computers , and some of the foundations of statistical mechanics and quantum mechanics . Many mathematically inclined scientists, including Galileo , were also musicians . There are many compelling stories in medicine and biology , such as the development of ideas about the circulation of blood from Galen to Harvey . Some scholars and historians attributes Christianity to having contributed to
14948-554: The inhabitants of Constantinople continued to refer to themselves as Romans, as did their eventual conquerors in 1453, the Ottomans (see Romaioi and Rûm .) The classical scholarship and culture that was still preserved in Constantinople were brought by refugees fleeing its conquest in 1453 and helped to begin the Renaissance (see Greek scholars in the Renaissance ). Ultimately, it was a slow, complex, and graduated change of
15096-412: The language, politics, law, educational systems, philosophy , science, warfare, literature, historiography, ethics, rhetoric, art and architecture of both the Western , and through it, the modern world. Surviving fragments of classical culture helped produce a revival beginning during the 14th century which later came to be known as the Renaissance , and various neo-classical revivals occurred during
15244-533: The latter two of which were formerly Spartan allies, challenged Spartan dominance in the Corinthian War , which ended inconclusively in 387 BC. Later, in 371 BC, the Theban generals Epaminondas and Pelopidas won a victory at the Battle of Leuctra . The result of this battle was the end of Spartan supremacy and the establishment of Theban hegemony . Thebes sought to maintain its dominance until it
15392-517: The level of graduate schools . Upon completion, they would normally attain an academic degree , with the highest degree being a doctorate such as a Doctor of Philosophy (PhD). Although graduate education for scientists varies among institutions and countries, some common training requirements include specializing in an area of interest, publishing research findings in peer-reviewed scientific journals and presenting them at scientific conferences , giving lectures or teaching , and defending
15540-499: The mathematician Luca Pacioli . In Venice, Leonardo was employed as a military architect and engineer, devising methods to defend the city from naval attack. On his return to Florence in 1500, he and his household were guests of the Servite monks at the monastery of Santissima Annunziata and were provided with a workshop where, according to Vasari, Leonardo created the cartoon of The Virgin and Child with Saint Anne and Saint John
15688-405: The next thirty years. Salaì executed a number of paintings under the name of Andrea Salaì, but although Vasari claims that Leonardo "taught him many things about painting," his work is generally considered to be of less artistic merit than others among Leonardo's pupils, such as Marco d'Oggiono and Boltraffio . At the time of his death in 1524, Salaì owned a painting referred to as Joconda in
15836-739: The only two large equestrian statues of the Renaissance, Donatello 's Gattamelata in Padua and Verrocchio's Bartolomeo Colleoni in Venice, and became known as the Gran Cavallo . Leonardo completed a model for the horse and made detailed plans for its casting , but in November 1494, Ludovico gave the metal to his brother-in-law to be used for a cannon to defend the city from Charles VIII of France . Contemporary correspondence records that Leonardo and his assistants were commissioned by
15984-750: The overthrow of the Monarchy c. 509 BC and lasted more than 450 years until its subversion through a series of civil wars , into the Principate form of government and the Imperial period. During the half millennium of the Republic, Rome increased from a regional power of the Latium to the dominant force in Italy and beyond. The unification of Italy by the Romans was a gradual process, brought about by
16132-482: The painting in Verrocchio's workshop was done by his assistants. According to Vasari, Leonardo collaborated with Verrocchio on his The Baptism of Christ ( c. 1472–1475 ), painting the young angel holding Jesus's robe with skill so far superior to his master's that Verrocchio purportedly put down his brush and never painted again (the latter claim probably being apocryphal). The new technique of oil paint
16280-448: The painting is barely begun, the composition can be seen and is very unusual. Jerome , as a penitent , occupies the middle of the picture, set on a slight diagonal and viewed somewhat from above. His kneeling form takes on a trapezoid shape, with one arm stretched to the outer edge of the painting and his gaze looking in the opposite direction. J. Wasserman points out the link between this painting and Leonardo's anatomical studies. Across
16428-430: The painting was abandoned. The third important work of this period is the Virgin of the Rocks , commissioned in Milan for the Confraternity of the Immaculate Conception. The painting, to be done with the assistance of the de Predis brothers , was to fill a large complex altarpiece . Leonardo chose to paint an apocryphal moment of the infancy of Christ when the infant John the Baptist , in protection of an angel, met
16576-583: The papacy (as Leo X); Leonardo went to Rome that September, where he was received by the pope's brother Giuliano . From September 1513 to 1516, Leonardo spent much of his time living in the Belvedere Courtyard in the Apostolic Palace , where Michelangelo and Raphael were both active. Leonardo was given an allowance of 33 ducats a month and, according to Vasari, decorated a lizard with scales dipped in quicksilver . The pope gave him
16724-447: The recent awareness and admiration of Leonardo as a scientist and inventor, for the better part of four hundred years his fame rested on his achievements as a painter. A handful of works that are either authenticated or attributed to him have been regarded as among the great masterpieces. These paintings are famous for a variety of qualities that have been much imitated by students and discussed at great length by connoisseurs and critics. By
16872-528: The refectory of the Convent of Santa Maria della Grazie in Milan. It represents the last meal shared by Jesus with his disciples before his capture and death, and shows the moment when Jesus has just said "one of you will betray me", and the consternation that this statement caused. The writer Matteo Bandello observed Leonardo at work and wrote that some days he would paint from dawn till dusk without stopping to eat and then not paint for three or four days at
17020-422: The rise of the Scientific Revolution . During the age of Enlightenment, Luigi Galvani , the pioneer of bioelectromagnetics , discovered animal electricity. He discovered that a charge applied to the spinal cord of a frog could generate muscular spasms throughout its body. Charges could make frog legs jump even if the legs were no longer attached to a frog. While cutting a frog leg, Galvani's steel scalpel touched
17168-504: The same time as Leibniz ). He provided a comprehensive formulation of classical mechanics and investigated light and optics. Fourier founded a new branch of mathematics — infinite, periodic series — studied heat flow and infrared radiation , and discovered the greenhouse effect . Girolamo Cardano , Blaise Pascal Pierre de Fermat , Von Neumann , Turing , Khinchin , Markov and Wiener , all mathematicians, made major contributions to science and probability theory , including
17316-503: The sea to Florence, in order to allow a supply of water to sustain the canal during all seasons. Leonardo had left Borgia's service and returned to Florence by early 1503, where he rejoined the Guild of Saint Luke on 18 October of that year. By this same month, Leonardo had begun working on a portrait of Lisa del Giocondo , the model for the Mona Lisa , which he would continue working on until his twilight years. In January 1504, he
17464-575: The service of Ludovico Sforza in Milan. Later, he worked in Florence and Milan again, as well as briefly in Rome , all while attracting a large following of imitators and students. Upon the invitation of Francis I , he spent his last three years in France, where he died in 1519. Since his death, there has not been a time where his achievements, diverse interests, personal life , and empirical thinking have failed to incite interest and admiration, making him
17612-488: The socio-economic structure in European history that resulted in the changeover between classical antiquity and medieval society and no specific date can truly exemplify that. In politics, the late Roman conception of the Empire as a universal state, commanded by one supreme divinely appointed ruler, united with Christianity as a universal religion likewise headed by a supreme patriarch , proved very influential, even after
17760-422: The son of a Lombard aristocrat, who is considered to have been his favourite student. The Council of Florence wished Leonardo to return promptly to finish The Battle of Anghiari , but he was given leave at the behest of Louis XII , who considered commissioning the artist to make some portraits. Leonardo may have commenced a project for an equestrian figure of d'Amboise; a wax model survives and, if genuine,
17908-640: The son-in-law of Servius Tullius , Superbus was of Etruscan birth. It was during his reign that the Etruscans reached their apex of power. Superbus removed and destroyed all the Sabine shrines and altars from the Tarpeian Rock , enraging the people of Rome. The people came to object to his rule when he failed to recognize the rape of Lucretia , a patrician Roman, by his own son. Lucretia's kinsman, Lucius Junius Brutus (ancestor to Marcus Brutus ), summoned
18056-725: The state, as can be seen in the architecture of the Panthéon , the Arc de Triomphe , and the paintings of Jacques-Louis David . During the revolution, France transitioned from kingdom to republic to dictatorship to Empire (complete with Imperial Eagles) that the Romans had experienced centuries earlier. Classical antiquity is a general term for a long period of cultural history . Such a wide sampling of history and territory covers many rather disparate cultures and periods. "Classical antiquity" often refers to an idealized vision of later people, of what was, in Edgar Allan Poe 's words, "the glory that
18204-477: The strict rules of the classical unities derived from Aristotle's Poetics . The desire to dance in a manner allegedly similar to the manner of the ancient Greeks caused Isadora Duncan to create her brand of ballet . Leonardo da Vinci Leonardo di ser Piero da Vinci (15 April 1452 – 2 May 1519) was an Italian polymath of the High Renaissance who was active as
18352-461: The term scientist came into regular use after it was coined by the theologian , philosopher , and historian of science William Whewell in 1833. The roles of "scientists", and their predecessors before the emergence of modern scientific disciplines, have evolved considerably over time. Scientists of different eras (and before them, natural philosophers, mathematicians, natural historians, natural theologians, engineers, and others who contributed to
18500-646: The term scientist in 1833, and it first appeared in print in Whewell's anonymous 1834 review of Mary Somerville 's On the Connexion of the Physical Sciences published in the Quarterly Review . Whewell wrote of "an increasing proclivity of separation and dismemberment" in the sciences; while highly specific terms proliferated—chemist, mathematician, naturalist—the broad term "philosopher"
18648-454: The thermometer and telescope which allowed him to observe and clearly describe the solar system. Descartes was not only a pioneer of analytic geometry but formulated a theory of mechanics and advanced ideas about the origins of animal movement and perception . Vision interested the physicists Young and Helmholtz , who also studied optics , hearing and music . Newton extended Descartes's mathematics by inventing calculus (at
18796-765: The two Este sisters, Beatrice and Isabella . While on a journey that took him through Mantua , he drew a portrait of Isabella that appears to have been used to create a painted portrait, now lost. Beyond friendship, Leonardo kept his private life secret. His sexuality has been the subject of satire, analysis, and speculation. This trend began in the mid-16th century and was revived in the 19th and 20th centuries, most notably by Sigmund Freud in his Leonardo da Vinci, A Memory of His Childhood . Leonardo's most intimate relationships were perhaps with his pupils Salaì and Melzi . Melzi, writing to inform Leonardo's brothers of his death, described Leonardo's feelings for his pupils as both loving and passionate. It has been claimed since
18944-577: The victory of King Sargon II in 709 BC over the seven kings of the island, marking an important part of the transfer of Cyprus from Tyrian rule to the Neo-Assyrian Empire . The Archaic period followed the Greek Dark Ages , and saw significant advancements in political theory , and the beginnings of democracy , philosophy , theatre , poetry , as well as the revitalization of the written language (which had been lost during
19092-513: The young Leonardo was the first to suggest making the Arno river a navigable channel between Florence and Pisa . In January 1478, Leonardo received an independent commission to paint an altarpiece for the Chapel of Saint Bernard in the Palazzo Vecchio , an indication of his independence from Verrocchio's studio. An anonymous early biographer, known as Anonimo Gaddiano , claims that in 1480 Leonardo
19240-534: Was Greece , the grandeur that was Rome !" During the 18th and 19th centuries AD, reverence for classical antiquity was much greater in Europe and the United States than it is now. Respect for the ancient people of Greece and Rome affected politics , philosophy , sculpture , literature , theatre , education , architecture , and sexuality . Epic poetry in Latin continued to be written and circulated well into
19388-540: Was 65, which may indicate why he left works such as the Mona Lisa unfinished. He continued to work at some capacity until eventually becoming ill and bedridden for several months. Leonardo died at Clos Lucé on 2 May 1519 at the age of 67, possibly of a stroke. Francis I had become a close friend. Vasari describes Leonardo as lamenting on his deathbed, full of repentance, that "he had offended against God and men by failing to practice his art as he should have done." Vasari states that in his last days, Leonardo sent for
19536-598: Was a theologian and historian of Protestantism; the astronomer and physician Nicolaus Copernicus was a priest. During the Italian Renaissance scientists like Leonardo da Vinci , Michelangelo , Galileo Galilei and Gerolamo Cardano have been considered the most recognizable polymaths. During the Renaissance , Italians made substantial contributions in science. Leonardo da Vinci made significant discoveries in paleontology and anatomy. The Father of modern Science, Galileo Galilei , made key improvements on
19684-482: Was a very great philosopher." Salaì , or Il Salaino ("The Little Unclean One", i.e., the devil), entered Leonardo's household in 1490 as an assistant. After only a year, Leonardo made a list of his misdemeanours, calling him "a thief, a liar, stubborn, and a glutton," after he had made off with money and valuables on at least five occasions and spent a fortune on clothes. Nevertheless, Leonardo treated him with great indulgence, and he remained in Leonardo's household for
19832-542: Was about the time of the death of Verrocchio's master, the great sculptor Donatello . Leonardo became an apprentice by the age of 17 and remained in training for seven years. Other famous painters apprenticed in the workshop or associated with it include Ghirlandaio , Perugino , Botticelli , and Lorenzo di Credi . Leonardo was exposed to both theoretical training and a wide range of technical skills, including drafting, chemistry, metallurgy, metal working, plaster casting, leather working, mechanics, and woodwork, as well as
19980-559: Was applied to areas of the mostly tempera work, including the landscape, the rocks seen through the brown mountain stream, and much of Jesus's figure, indicating Leonardo's hand. Additionally, Leonardo may have been a model for two works by Verrocchio: the bronze statue of David in the Bargello and the archangel Raphael in Tobias and the Angel . Vasari tells a story of Leonardo as
20128-549: Was back in Milan, living in his own house in Porta Orientale in the parish of Santa Babila. In 1512, Leonardo was working on plans for an equestrian monument for Gian Giacomo Trivulzio , but this was prevented by an invasion of a confederation of Swiss, Spanish and Venetian forces, which drove the French from Milan. Leonardo stayed in the city, spending several months in 1513 at the Medici's Vaprio d'Adda villa. In March 1513, Lorenzo de' Medici's son Giovanni assumed
20276-460: Was born on 15 April 1452 in, or close to, the Tuscan hill town of Vinci , 20 miles from Florence . He was born out of wedlock to Piero da Vinci (Ser Piero da Vinci d'Antonio di ser Piero di ser Guido; 1426–1504), a Florentine legal notary , and Caterina di Meo Lippi ( c. 1434–1494 ), from the lower class. It remains uncertain where Leonardo was born; the traditional account, from
20424-484: Was born when Leonardo was 46 years old) and with whom he had very little contact. Very little is known about Leonardo's childhood and much is shrouded in myth, partially because of his biography in the frequently apocryphal Lives of the Most Excellent Painters, Sculptors, and Architects (1550) by 16th-century art historian Giorgio Vasari . Tax records indicate that by at least 1457 he lived in
20572-718: Was emperor Maurice , who reigned until 602. The overthrow of Maurice by his mutinying Danube army commanded by Phocas resulted in the Slavic invasion of the Balkans and the weakening of Balkan and Greek urban culture (resulting in the flight of Balkan Latin speakers to the mountains, see Origin of the Romanians ), and also provoked the Byzantine–Sasanian War of 602–628 in which all the great eastern cities except Constantinople were lost. The resulting turmoil did not end until
20720-669: Was finally ended by the increasing power of Macedon in 346 BC. During the reign of Philip II , (359–336 BC), Macedon expanded into the territory of the Paeonians , the Thracians and the Illyrians . Philip's son, Alexander the Great , (356–323 BC) managed to briefly extend Macedonian power not only over the central Greek city-states but also to the Persian Empire , including Egypt and lands as far east as
20868-597: Was living with the Medici and often worked in the garden of the Piazza San Marco, Florence , where a Neoplatonic academy of artists, poets and philosophers organised by the Medici met. In March 1481, he received a commission from the monks of San Donato in Scopeto for The Adoration of the Magi . Neither of these initial commissions were completed, being abandoned when Leonardo went to offer his services to Duke of Milan Ludovico Sforza . Leonardo wrote Sforza
21016-416: Was no longer satisfactory to group together those who pursued science, without the caveats of "natural" or "experimental" philosopher. Whewell compared these increasing divisions with Somerville's aim of "[rendering] a most important service to science" "by showing how detached branches have, in the history of science, united by the discovery of general principles." Whewell reported in his review that members of
21164-441: Was not generally palatable". Whewell proposed the word again more seriously (and not anonymously) in his 1840 The Philosophy of the Inductive Sciences : The terminations ize (rather than ise ), ism , and ist , are applied to words of all origins: thus we have to pulverize , to colonize , Witticism , Heathenism , Journalist , Tobacconist . Hence we may make such words when they are wanted. As we cannot use physician for
21312-432: Was of ground-breaking importance in terms of composition. Two of the three were never finished, and the third took so long that it was subject to lengthy negotiations over completion and payment. One of these paintings was Saint Jerome in the Wilderness , which Bortolon associates with a difficult period of Leonardo's life, as evidenced in his diary: "I thought I was learning to live; I was only learning to die." Although
21460-472: Was part of a committee formed to recommend where Michelangelo's statue of David should be placed. He then spent two years in Florence designing and painting a mural of The Battle of Anghiari for the Signoria, with Michelangelo designing its companion piece, The Battle of Cascina . In 1506, Leonardo was summoned to Milan by Charles II d'Amboise , the acting French governor of the city. There, Leonardo took on another pupil, Count Francesco Melzi ,
21608-437: Was strong among the Founding Fathers of the United States and the Latin American revolutionaries; the Americans described their new government as a republic (from res publica ) and gave it a Senate and a President (another Latin term), rather than use available English terms like commonwealth or parliament . Similarly in Revolutionary and Napoleonic France, republicanism and Roman martial virtues were promoted by
21756-425: Was struck by the equestrian statue of Regisole , of which he left a sketch. Leonardo was employed on many other projects for Sforza, such as preparation of floats and pageants for special occasions; a drawing of , and wooden model for, a competition to design the cupola for Milan Cathedral ; and a model for a huge equestrian monument to Ludovico's predecessor Francesco Sforza . This would have surpassed in size
21904-522: Was supported by a pension totalling 10,000 scudi . At some point, Melzi drew a portrait of Leonardo ; the only others known from his lifetime were a sketch by an unknown assistant on the back of one of Leonardo's studies ( c. 1517 ) and a drawing by Giovanni Ambrogio Figino depicting an elderly Leonardo with his right arm wrapped in clothing. The latter, in addition to the record of an October 1517 visit by Louis d'Aragon , confirms an account of Leonardo's right hand being paralytic when he
