Monas Hieroglyphica (or The Hieroglyphic Monad ) is a book by John Dee , the Elizabethan magus and court astrologer of Elizabeth I of England , published in Antwerp in 1564. It is an exposition of the meaning of an esoteric symbol that he invented.
74-610: Dee's Monas Hieroglyphica presents a complex emblem constructed from various astrological symbols, with elements of Latin wordplay, capitalization, spacing, and diacritics, rendering its interpretation challenging. The symbol is intended to embody a profound concept, representing the unity of all creation influenced by celestial forces. Dee believed that this symbol contained the essence of alchemical transformation and spiritual evolution, and by meditating upon it, he aimed to access hidden knowledge transcending linguistic barriers. In merging astrology , alchemy , mysticism , and metaphysics ,
148-483: A neoplatonist , argued that since the fixed stars are much more distant than the planets, it is laughable to imagine the planets' effect on human affairs should depend on their position with respect to the zodiac. He also argues that the interpretation of the Moon's conjunction with a planet as good when the moon is full, but bad when the moon is waning, is clearly wrong, as from the Moon's point of view, half of its surface
222-516: A "convincing distinction between astrology and astronomy that remains valid in the twenty-first century." Cicero stated the twins objection (that with close birth times, personal outcomes can be very different), later developed by Augustine . He argued that since the other planets are much more distant from the Earth than the Moon, they could have only very tiny influence compared to the Moon's. He also argued that if astrology explains everything about
296-400: A "rationalistic and critical thinker", was much more sanguine about astrology and critical of Pico's attack. Renaissance scholars commonly practised astrology. Gerolamo Cardano cast the horoscope of king Edward VI of England , while John Dee was the personal astrologer to queen Elizabeth I of England . Catherine de Medici paid Michael Nostradamus in 1566 to verify the prediction of
370-580: A Greek origin for Hindu astrology. The Indian techniques may also have been augmented with some of the Babylonian techniques. Chinese astrology has a close relation with Chinese philosophy (theory of the three harmonies: heaven, earth and man) and uses concepts such as yin and yang , the Five phases , the 10 Celestial stems , the 12 Earthly Branches , and shichen (時辰 a form of timekeeping used for religious purposes). The early use of Chinese astrology
444-400: A communal calendar. Farmers addressed agricultural needs with increasing knowledge of the constellations that appear in the different seasons—and used the rising of particular star-groups to herald annual floods or seasonal activities. By the 3rd millennium BCE, civilisations had sophisticated awareness of celestial cycles, and may have oriented temples in alignment with heliacal risings of
518-683: A fearful consideration for the sky and the stars, which they held to be ultimately responsible for every phenomena that occurs on Earth and for the destiny of humankind. Accordingly, they shaped their entire lives in accordance with their interpretations of astral configurations and phenomena. The Hellenistic schools of philosophical skepticism criticized the rationality of astrology. Criticism of astrology by academic skeptics such as Cicero , Carneades , and Favorinus ; and Pyrrhonists such as Sextus Empiricus has been preserved. Carneades argued that belief in fate denies free will and morality ; that people born at different times can all die in
592-446: A person's fate, then it wrongly ignores the visible effect of inherited ability and parenting, changes in health worked by medicine, or the effects of the weather on people. Favorinus argued that it was absurd to imagine that stars and planets would affect human bodies in the same way as they affect the tides, and equally absurd that small motions in the heavens cause large changes in people's fates. Sextus Empiricus argued that it
666-582: A popular following supported by cheap almanacs. One English almanac compiler, Richard Saunders, followed the spirit of the age by printing a derisive Discourse on the Invalidity of Astrology , while in France Pierre Bayle's Dictionnaire of 1697 stated that the subject was puerile. The Anglo-Irish satirist Jonathan Swift ridiculed the Whig political astrologer John Partridge . In
740-595: Is always in sunlight; and from the planet's point of view, waning should be better, as then the planet sees some light from the Moon, but when the Moon is full to us, it is dark, and therefore bad, on the side facing the planet in question. In 525 BCE, Egypt was conquered by the Persians. The 1st century BCE Egyptian Dendera Zodiac shares two signs – the Balance and the Scorpion – with Mesopotamian astrology. With
814-571: Is based are early medieval compilations, notably the Bṛhat Parāśara Horāśāstra , and Sārāvalī by Kalyāṇavarma . The Horāshastra is a composite work of 71 chapters, of which the first part (chapters 1–51) dates to the 7th to early 8th centuries and the second part (chapters 52–71) to the later 8th century. The Sārāvalī likewise dates to around 800 CE. English translations of these texts were published by N.N. Krishna Rau and V.B. Choudhari in 1963 and 1961, respectively. Astrology

It is also reproduced in the English logician, mathematician, and medic Thomas Oliver ’s De Sophismatum praestigijs cauendis admonitio (1604). His further comments in the work suggest that he was also familiar with Dee’s "Mathematicall Praeface" to Billingsley’s translation of Euclid’s Elements of Geometrie (1570). Giulio Cesare Capaccio refers to
962-568: Is praised in the 1591 edition of George Ripley 's The Compound of Alchymy as well as in Elias Ashmole ’s Theatrum Chemicum Britannicum (1652). A number of references appear in other languages, for example, Jean-Jacques Manget ’s Bibliotheca Chemica Curiosa (1702) and Lazarus Zetzner’s Theatrum Chemicum (1602; 1659–1661); the latter reproduces the Monas Hieroglyphica in its entirety. Gerard Dorn 's Judgement of
1036-811: Is said to represent twelve different types of personality . It is based on cycles of years, lunar months, and two-hour periods of the day (the shichen). The zodiac traditionally begins with the sign of the Rat , and the cycle proceeds through 11 other animal signs: the Ox , Tiger , Rabbit , Dragon , Snake , Horse , Goat , Monkey , Rooster , Dog , and Pig . Complex systems of predicting fate and destiny based on one's birthday, birth season, and birth hours, such as ziping and Zi Wei Dou Shu ( simplified Chinese : 紫微斗数 ; traditional Chinese : 紫微斗數 ; pinyin : zǐwēidǒushù ) are still used regularly in modern-day Chinese astrology. They do not rely on direct observations of
1110-638: Is the aspect of each planet to every other planet, where for example two planets 120° apart (in 'trine') are in a harmonious relationship, but two planets 90° apart ('square') are in a conflicted relationship. Together these relationships and their interpretations are said to form "...the language of the heavens speaking to learned men." Along with tarot divination , astrology is one of the core studies of Western esotericism , and as such has influenced systems of magical belief not only among Western esotericists and Hermeticists , but also belief systems such as Wicca , which have borrowed from or been influenced by
1184-407: Is the search for meaning in the sky. Early evidence for humans making conscious attempts to measure, record, and predict seasonal changes by reference to astronomical cycles, appears as markings on bones and cave walls, which show that lunar cycles were being noted as early as 25,000 years ago. This was a first step towards recording the Moon's influence upon tides and rivers, and towards organising
1258-656: Is used in a more alchemical context. The glyph was adopted by the Rosicrucians and appears on a page of the Rosicrucian manifesto Chymical Wedding of Christian Rosenkreutz (1616), beside the text of the invitation to the Royal Wedding given to Christian Rosenkreuz , who narrates the work. Frances Yates notes that Dee's influence later "spread to Puritanism in the New World through John Winthrop
1332-654: The Tetrabiblos formed the basis of Western astrology, and, "...enjoyed almost the authority of a Bible among the astrological writers of a thousand years or more." The conquest of Asia by Alexander the Great exposed the Greeks to ideas from Syria , Babylon, Persia and central Asia. Around 280 BCE, Berossus , a priest of Bel from Babylon, moved to the Greek island of Kos , teaching astrology and Babylonian culture. By
1406-560: The Latin translations of the 12th century . In the seventh century, Isidore of Seville argued in his Etymologiae that astronomy described the movements of the heavens, while astrology had two parts: one was scientific, describing the movements of the Sun, the Moon and the stars, while the other, making predictions, was theologically erroneous. The first astrological book published in Europe

Cesare della Riviera includes Dee's glyph, without attribution, in his Il Mondo Magico de gli Heroi (1605). The glyph is also reproduced in the Amphitheatrum sapientiae aeternae (1595; 1609) of Heinrich Khunrath , where it

Why is it that you have given an influence to al-Ra's [the head] and al-Dhanab [the tail], which are two imaginary points [ascending and descending nodes] ? Martin Luther denounced astrology in his Table Talk . He asked why twins like Esau and Jacob had two different natures yet were born at

They are also considered by their placement in houses (twelve spatial divisions of the sky). Astrology's modern representation in western popular media is usually reduced to sun sign astrology , which considers only the zodiac sign of the Sun at an individual's date of birth, and represents only 1/12 of
1702-598: The zodiac , a norming point near 9 degrees in Aries, the trine aspect, planetary exaltations, and the dodekatemoria (the twelve divisions of 30 degrees each). The Babylonians viewed celestial events as possible signs rather than as causes of physical events. The system of Chinese astrology was elaborated during the Zhou dynasty (1046–256 BCE) and flourished during the Han dynasty (2nd century BCE to 2nd century CE), during which all
1776-799: The 1st century BCE, there were two varieties of astrology, one using horoscopes to describe the past, present and future; the other, theurgic , emphasising the soul's ascent to the stars. Greek influence played a crucial role in the transmission of astrological theory to Rome . The first definite reference to astrology in Rome comes from the orator Cato , who in 160 BCE warned farm overseers against consulting with Chaldeans, who were described as Babylonian 'star-gazers'. Among both Greeks and Romans , Babylonia (also known as Chaldea ) became so identified with astrology that 'Chaldean wisdom' became synonymous with divination using planets and stars. The 2nd-century Roman poet and satirist Juvenal complains about
1850-548: The 2nd millennium BCE, these practices having originated in calendrical systems used to predict seasonal shifts and to interpret celestial cycles as signs of divine communications. Most, if not all, cultures have attached importance to what they observed in the sky, and some—such as the Hindus , Chinese , and the Maya —developed elaborate systems for predicting terrestrial events from celestial observations. Western astrology , one of

The names of the signs (e.g. Greek 'Krios' for Aries, Hindi 'Kriya'), the planets (e.g. Greek 'Helios' for Sun, astrological Hindi 'Heli'), and astrological terms (e.g. Greek 'apoklima' and 'sunaphe' for declination and planetary conjunction, Hindi 'apoklima' and 'sunapha' respectively) in Varaha Mihira's texts are considered conclusive evidence of
1998-518: The Catholic Church maintains that divination, including predictive astrology, is incompatible with modern Catholic beliefs such as free will: All forms of divination are to be rejected: recourse to Satan or demons, conjuring up the dead or other practices falsely supposed to "unveil" the future. Consulting horoscopes, astrology, palm reading, interpretation of omens and lots, the phenomena of clairvoyance, and recourse to mediums all conceal
2072-529: The Egyptian concept of dividing the zodiac into thirty-six decans of ten degrees each, with an emphasis on the rising decan, and the Greek system of planetary Gods, sign rulership and four elements . 2nd century BCE texts predict positions of planets in zodiac signs at the time of the rising of certain decans, particularly Sothis. The astrologer and astronomer Ptolemy lived in Alexandria. Ptolemy's work
2146-404: The English mathematician and physician Thomas Hood made a set of paper instruments that used revolving overlays to help students work out relationships between fixed stars or constellations, the midheaven, and the twelve astrological houses . Hood's instruments also illustrated, for pedagogical purposes, the supposed relationships between the signs of the zodiac, the planets, and the parts of
2220-553: The Great's conquest of Asia allowed astrology to spread to Ancient Greece and Rome . In Rome, astrology was associated with " Chaldean wisdom". After the conquest of Alexandria in the 7th century, astrology was taken up by Islamic scholars, and Hellenistic texts were translated into Arabic and Persian. In the 12th century, Arabic texts were imported to Europe and translated into Latin . Major astronomers including Tycho Brahe , Johannes Kepler and Galileo practised as court astrologers. Astrological references appear in literature in
2294-575: The Hieroglyphic Monad serves as a visual manifestation of Dee's interconnected worldview. Understanding the text is difficult because of Dee's Latin wordplay, unexplained capitalization, odd spacing and diacritics . John Dee intended the Monad to incorporate a wide range of mystical and esoteric concepts. This complex symbol was meant to symbolize the unity of all creation, influenced by astrological and planetary forces. Dee believed it held

2368-512: The Latin astronomia ). By the 17th century , astronomy became established as the scientific term, with astrology referring to divinations and schemes for predicting human affairs. Many cultures have attached importance to astronomical events, and the Indians , Chinese , and Maya developed elaborate systems for predicting terrestrial events from celestial observations. A form of astrology

Tanya Luhrmann has said that "all magicians know something about astrology," and refers to a table of correspondences in Starhawk's The Spiral Dance , organised by planet , as an example of the astrological lore studied by magicians. The earliest Vedic text on astronomy is the Vedanga Jyotisha ; Vedic thought later came to include astrology as well. Hindu natal astrology originated with Hellenistic astrology by

For example, Avicenna's 'Refutation against astrology', Risāla fī ibṭāl aḥkām al-nojūm , argues against the practice of astrology while supporting the principle that planets may act as agents of divine causation. Avicenna considered that the movement of the planets influenced life on earth in a deterministic way, but argued against the possibility of determining

Astrology Astrology is a range of divinatory practices, recognized as pseudoscientific since the 18th century, that propose that information about human affairs and terrestrial events may be discerned by studying the apparent positions of celestial objects . Different cultures have employed forms of astrology since at least
2738-573: The death of her husband, king Henry II of France made by her astrologer Lucus Gauricus. Major astronomers who practised as court astrologers included Tycho Brahe in the royal court of Denmark, Johannes Kepler to the Habsburgs , Galileo Galilei to the Medici , and Giordano Bruno who was burnt at the stake for heresy in Rome in 1600. The distinction between astrology and astronomy was not entirely clear. Advances in astronomy were often motivated by
2812-502: The desire to improve the accuracy of astrology. Kepler, for example, was driven by a belief in harmonies between Earthly and celestial affairs, yet he disparaged the activities of most astrologers as "evil-smelling dung". Ephemerides with complex astrological calculations, and almanacs interpreting celestial events for use in medicine and for choosing times to plant crops, were popular in Elizabethan England. In 1597,
2886-550: The development of psychological astrology . Advocates have defined astrology as a symbolic language, an art form, a science , and a method of divination. Though most cultural astrology systems share common roots in ancient philosophies that influenced each other, many use methods that differ from those in the West. These include Hindu astrology (also known as "Indian astrology" and in modern times referred to as "Vedic astrology") and Chinese astrology, both of which have influenced

By meditating on the Monad, he thought to gain insights into hidden knowledge about the universe, transcending language barriers and tapping into profound truths. Overall, Dee's intention was to encapsulate his interconnected worldview, combining elements of astrology, alchemy, mysticism, and metaphysics. The book received little notice in English sources, though it

Essentially, Avicenna did not deny the core dogma of astrology, but denied our ability to understand it to the extent that precise and fatalistic predictions could be made from it. Ibn Qayyim al-Jawziyya (1292–1350), in his Miftah Dar al-SaCadah , also used physical arguments in astronomy to question the practice of judicial astrology. He recognised that the stars are much larger than

Some of the practices of astrology were contested on theological grounds by medieval Muslim astronomers such as Al-Farabi (Alpharabius), Ibn al-Haytham (Alhazen) and Avicenna . They said that the methods of astrologers conflicted with orthodox religious views of Islamic scholars , by suggesting that

The ancient Arabs that inhabited the Arabian Peninsula before the advent of Islam used to profess a widespread belief in fatalism ( ḳadar ) alongside
3256-546: The fifteenth century. In Paradiso , the final part of the Divine Comedy , the Italian poet Dante Alighieri referred "in countless details" to the astrological planets, though he adapted traditional astrology to suit his Christian viewpoint, for example using astrological thinking in his prophecies of the reform of Christendom . John Gower in the fourteenth century defined astrology as essentially limited to
3330-576: The first day of the fifth month in the Thai lunar calendar , or during the Songkran festival (now celebrated every 13–15 April), depending on the purpose of the use. Augustine (354–430) believed that the determinism of astrology conflicted with the Christian doctrines of man's free will and responsibility, and God not being the cause of evil, but he also grounded his opposition philosophically, citing
3404-536: The gods revealed to him in a dream the constellations that would be most favourable for the planned construction of a temple. However, there is controversy about whether these were genuinely recorded at the time or merely ascribed to ancient rulers by posterity. The oldest undisputed evidence of the use of astrology as an integrated system of knowledge is therefore attributed to the records of the first dynasty of Babylon (1950–1651 BCE). This astrology had some parallels with Hellenistic Greek (western) astrology, including
3478-525: The human body adherents believed were governed by the planets and signs. While Hood's presentation was innovative, his astrological information was largely standard and was taken from Gerard Mercator's astrological disc made in 1551, or a source used by Mercator. Despite its popularity, Renaissance astrology had what historian Gabor Almasi calls "elite debate", exemplified by the polemical letters of Swiss physician Thomas Erastus who fought against astrology, calling it "vanity" and "superstition." Then around
3552-503: The making of predictions. The influence of the stars was in turn divided into natural astrology, with for example effects on tides and the growth of plants, and judicial astrology, with supposedly predictable effects on people. The fourteenth-century sceptic Nicole Oresme however included astronomy as a part of astrology in his Livre de divinacions . Oresme argued that current approaches to prediction of events such as plagues, wars, and weather were inappropriate, but that such prediction

The city of Alexandria was founded by Alexander after the conquest, becoming the place where Babylonian astrology was mixed with Egyptian Decanic astrology to create Horoscopic astrology . This contained the Babylonian zodiac with its system of planetary exaltations , the triplicities of the signs and the importance of eclipses. It used
3700-462: The oldest astrological systems still in use, can trace its roots to 19th–17th century BCE Mesopotamia , from where it spread to Ancient Greece, Rome, the Islamic world , and eventually Central and Western Europe. Contemporary Western astrology is often associated with systems of horoscopes that purport to explain aspects of a person's personality and predict significant events in their lives based on
3774-566: The pervasive influence of Chaldeans, saying, "Still more trusted are the Chaldaeans; every word uttered by the astrologer they will believe has come from Hammon's fountain." One of the first astrologers to bring Hermetic astrology to Rome was Thrasyllus , astrologer to the emperor Tiberius , the first emperor to have had a court astrologer, though his predecessor Augustus had used astrology to help legitimise his Imperial rights.

Throughout its history, astrology has had its detractors, competitors and skeptics who opposed it for moral, religious, political, and empirical reasons. Nonetheless, prior to the Enlightenment, astrology was generally considered a scholarly tradition and was common in learned circles, often in close relation with astronomy , meteorology , medicine , and alchemy .

Cicero , in De Divinatione , leveled a critique of astrology that some modern philosophers consider to be the first working definition of pseudoscience and the answer to the demarcation problem . Philosopher of Science Massimo Pigliucci , building on the work of Historian of Science, Damien Fernandez-Beanato, argues that Cicero outlined

Although the dice may roll on the number a couple of times, the predictor is silent for all the times the dice fails to land on that number.

Following the template of the popular "Feasts of Mathematicians" they endeavored to defend their art in the face of growing religious criticism. The Society hosted banquets, exchanged "instruments and manuscripts", proposed research projects, and funded

The word astrology comes from the early Latin word astrologia , which derives from the Greek ἀστρολογία —from ἄστρον astron ("star") and -λογία -logia , ("study of"—"account of the stars"). The word entered the English language via Latin and medieval French , and its use overlapped considerably with that of astronomy (derived from

Throughout most of its history, astrology was considered a scholarly tradition. It was accepted in political and academic contexts, and was connected with other studies, such as astronomy , alchemy , meteorology , and medicine. At the end of the 17th century, new scientific concepts in astronomy and physics (such as heliocentrism and Newtonian mechanics ) called astrology into question. Astrology thus lost its academic and theoretical standing, and common belief in astrology has largely declined. Astrology, in its broadest sense,

It uses the tropical zodiac, which is aligned to the equinoctial points . Western astrology is founded on the movements and relative positions of celestial bodies such as the Sun, Moon and planets, which are analysed by their movement through signs of

However, he attacked the use of astrology to choose the timing of actions (so-called interrogation and election) as wholly false, and rejected the determination of human action by the stars on grounds of free will. The friar Laurens Pignon (c. 1368–1449) similarly rejected all forms of divination and determinism, including by the stars, in his 1411 Contre les Devineurs . This

In the late 15th century, Giovanni Pico della Mirandola forcefully attacked astrology in Disputationes contra Astrologos , arguing that the heavens neither caused, nor heralded earthly events. His contemporary, Pietro Pomponazzi ,

The text is dated between 1400 BCE to final centuries BCE by various scholars according to astronomical and linguistic evidences. Chinese astrology was elaborated in the Zhou dynasty (1046–256 BCE). Hellenistic astrology after 332 BCE mixed Babylonian astrology with Egyptian Decanic astrology in Alexandria , creating horoscopic astrology . Alexander

During the Enlightenment , however, astrology lost its status as an area of legitimate scholarly pursuit. Following the end of the 19th century and the wide-scale adoption of the scientific method , researchers have successfully challenged astrology on both theoretical and experimental grounds, and have shown it to have no scientific validity or explanatory power . Astrology thus lost its academic and theoretical standing in
