An hourglass (or sandglass , sand timer , or sand clock ) is a device used to measure the passage of time . It comprises two glass bulbs connected vertically by a narrow neck that allows a regulated flow of a substance (historically sand ) from the upper bulb to the lower one due to gravity . Typically, the upper and lower bulbs are symmetric so that the hourglass will measure the same duration regardless of orientation. The specific duration of time a given hourglass measures is determined by factors including the quantity and coarseness of the particulate matter, the bulb size, and the neck width.

75-542: Depictions of an hourglass as a symbol of the passage of time are found in art, especially on tombstones or other monuments, from antiquity to the present day. The form of a winged hourglass has been used as a literal depiction of the Latin phrase tempus fugit ("time flies"). The origin of the hourglass is unclear. Its predecessor the clepsydra , or water clock , is known to have existed in Babylon and Egypt as early as

Laden with spices, they attempted to set sail for Spain in December, but found that only one of their remaining two ships, the Victoria , was seaworthy. The Victoria , captained by Juan Sebastián Elcano , finally returned to Spain by 6 September 1522, completing

225-651: A clepsydra). While hourglasses were insufficiently accurate to be compared against solar noon for the determination of a ship's longitude (as an error of just four minutes would correspond to one degree of longitude), they were sufficiently accurate to be used in conjunction with a chip log to enable the measurement of a ship's speed in knots . The hourglass also found popularity on land as an inexpensive alternative to mechanical clocks. Hourglasses were commonly seen in use in churches, homes, and work places to measure sermons, cooking time, and time spent on breaks from labor. Because they were being used for more everyday tasks,

300-413: A concept. The hourglass, sometimes with the addition of metaphorical wings, is often used as a symbol that human existence is fleeting, and that the " sands of time " will run out for every human life. It was used thus on pirate flags, to evoke fear through imagery associated with death. In England, hourglasses were sometimes placed in coffins, and they have graced gravestones for centuries. The hourglass

Recognizing the captain, so many turned upon him that they knocked his helmet off his head twice.... An Indian hurled a bamboo spear into the captain's face, but the latter immediately killed him with his lance, which he left in the Indian's body. Then, trying to lay hand on sword, he could draw it out but halfway, because he had been wounded in

They found a sheltered natural harbor at the port of Saint Julian , and remained there for five months. Shortly after landing at St. Julian, there was a mutiny attempt led by the Spanish captains Juan de Cartagena , Gaspar de Quesada and Luis de Mendoza . Magellan barely managed to quell

525-438: A hand-written copy of his notes from the journey. He would later travel through Europe giving copies to other royals including John III of Portugal , Francis I of France , and Philippe Villiers de L'Isle-Adam . After returning to his home of Venice, Pigafetta published his diary (as Relazione del primo viaggio intorno al mondo ) around 1524. Scholars have come to view Pigafetta's diary as the most thorough and reliable account of

600-441: A nearly complete personal circumnavigation of the globe for the first time in history. Magellan was born in northern Portugal c. 1480. His father, Pedro de Magalhães, was a minor member of Portuguese nobility and mayor of the town. His mother was Alda de Mezquita. Magellan's siblings included Diogo de Sousa and Isabel Magellan. He was brought up as a page of Queen Eleanor , consort of King John II . In 1495 he entered

Later in 1515, he was offered employment as a crew member on a Portuguese ship, but rejected this. In 1517, after a quarrel with Manuel I of Portugal, who denied his persistent requests to lead an expedition to reach the Spice Islands from

In the 21st century, the Extinction symbol came into use as a symbol of the Holocene extinction and climate crisis . The symbol features an hourglass to represent time "running out" for extinct and endangered species, and also to represent time "running out" for climate change mitigation . In modern mobile hidden object games,

900-494: A small force on the morning of 27 April 1521. During the resulting battle against Lapulapu's troops, Magellan was struck by a "bamboo" spear ( bangkaw , which are actually metal-tipped fire-hardened rattan ), and later surrounded and finished off with other weapons. Antonio Pigafetta and Ginés de Mafra provided written documents of the events culminating in Magellan's death: When morning came forty-nine of us leaped into

975-638: A storm while surveying nearby waters, though no men were killed. Following the winter, the fleet resumed their search for a passage to the Pacific in October 1520. Three days later, they found a bay which eventually led them to a strait, now known as the Strait of Magellan , which allowed them passage through to the Pacific. While exploring the strait, one of the remaining four ships, the San Antonio , deserted

1050-625: A timekeeper. For example, the American television soap opera Days of Our Lives (1965–present) displays an hourglass in its opening credits, with narration by Macdonald Carey : "Like sands through the hourglass, so are the days of our lives." Various computer graphical user interfaces may change the pointer to an hourglass while the program is in the middle of a task, and may not accept user input. During that period of time, other programs, such as those open in other windows, may work normally. When such an hourglass does not disappear, it suggests

1125-468: A western route, a feat never before accomplished. Bergreen further states that Magellan claimed to Charles that his Malaccan or Sumatran slave Enrique had been a native of the Spice Islands and used Enrique and letters from Serrão to "prove" that the islands were so far east that they would fall within the Spanish sphere of influence if the world were truly to be divided in half. (The details of

His letters to Magellan later proved decisive, giving information about the spice-producing territories. After taking a leave without permission, Magellan fell out of favour. In mid-1513 he was sent to fight against the Moroccan stronghold of Azemmour and there, in August, he sustained a leg wound resulting in

1275-528: Is a Latin phrase, usually translated into English as " time flies ". The expression comes from line 284 of book 3 of Virgil 's Georgics , where it appears as fugit irreparabile tempus : "it escapes, irretrievable time". The phrase is used in both its Latin and English forms as a proverb that "time's a-wasting". Tempus fugit is typically employed as an admonition against sloth and procrastination (cf. carpe diem ) rather than an argument for licentiousness (cf. " gather ye rosebuds while ye may ");

1350-444: Is the shape that it is. The glass bulbs used, however, have changed in style and design over time. While the main designs have always been ampoule in shape, the bulbs were not always connected. The first hourglasses were two separate bulbs with a cord wrapped at their union that was then coated in wax to hold the piece together and let sand flow in between. It was not until 1760 that both bulbs were blown together to keep moisture out of

1425-498: The Australian Parliament use three hourglasses to time certain procedures , such as divisions . Sand timers are sometimes included with boardgames such as Pictionary and Boggle that place time constraints on rounds of play. Unlike most other methods of measuring time, the hourglass concretely represents the present as being between the past and the future , and this has made it an enduring symbol of time as

1500-567: The British Museum in London. Not until the 18th century did John Harrison come up with a marine chronometer that significantly improved on the stability of the hourglass at sea. Taking elements from the design logic behind the hourglass, he made a marine chronometer in 1761 that was able to accurately measure the journey from England to Jamaica accurate within five seconds. Little written evidence exists to explain why its external form

His name has also since been applied to a variety of other entities , including the Magellanic Clouds (two dwarf galaxies visible in the night sky of the southern hemisphere), Project Magellan (a Cold War -era US Navy project to circumnavigate the world by submarine), and NASA's Magellan spacecraft . Even though Magellan did not survive

1650-819: The Spanish Empire . Granted special powers and privileges by the king, he led the Armada from Sanlucar de Barrameda southwest across the Atlantic Ocean, to the eastern coast of South America, and south to Patagonia . Despite a series of storms and mutinies, the expedition successfully passed through the Strait of Magellan into the Mar del Sur , which Magellan renamed the Mar Pacifico , or Pacific Ocean. The expedition landed at Guam after an arduous crossing of

1725-406: The 15th century onwards, hourglasses were being used in a range of applications at sea, in the church, in industry, and in cookery. During the voyage of Ferdinand Magellan around the globe, 18 hourglasses from Barcelona were in the ship's inventory, after the trip had been authorized by King Charles I of Spain . It was the job of a ship's page to turn the hourglasses and thus provide the times for

1800-528: The 16th century BCE. There are no records of the hourglass existing in Europe prior to the Late Middle Ages ; the first documented example dates from the 14th century, a depiction in the 1338 fresco Allegory of Good Government by Ambrogio Lorenzetti . Use of the marine sandglass has been recorded since the 14th century. The written records about it were mostly from logbooks of European ships. In

1875-532: The Atlantic toward South America. In late November, they made landfall at Cabo de Santo Agostinho , near present day Recife . The Tupi natives, having already engaged with Portuguese and French loggers, were familiar with Europeans, and the encounter was cordial. In December, they arrived at Guanabara Bay , the location of present-day Rio de Janeiro . Magellan and the crew stayed onshore for two weeks, replenishing their provisions and peacefully interacting with

1950-645: The Cebuanos. The king then told the Spaniards to go to the island of Mactan to kill his enemy Lapulapu . The Spaniards went to the island of Mactan just as Rajah Humabon told them to. However, they did not initially come by force and wanted to Christianize them. Unlike the people of Cebu who accepted the new religion readily, the King of Mactan, Datu Lapulapu, and the rest of the island of Mactan resisted. On 27 April, Magellan and members of his crew attempted to subdue

2025-558: The English form is often merely descriptive: "time flies like the wind", "time flies when you're having fun". The phrase is a common motto , particularly on sundials and clocks. It also has been used on gravestones . Some writers have attempted rebuttals: "Time goes, you say? Ah, no! alas, time stays, we go." by Henry Austin Dobson (1840–1921)."Hêd Amser! / Meddi Na! / Erys Amser / Dyn Â" on sundial at Univ of Bangor, North Wales. says

While in the Kingdom of Portugal 's service, Magellan had already reached the Malay Archipelago in Southeast Asia on previous voyages traveling east (from 1505 to 1511–1512). By visiting this area again but now traveling west, Magellan achieved

2175-526: The Kingdom of Cebu (Sugbo). To mark the arrival of Christianity in the Far East, Magellan then planted a Cross on the shorelines of the kingdom. Magellan set about converting the locals, including the king and his wife, Queen Humamay, to Christianity. Rajah Humabon was renamed "Carlos" and Queen Humamay was renamed "Juana" after the king and queen of Spain. After her baptism, the queen asked the Spaniards for

2250-595: The Mactan natives by force, but in the ensuing battle , the Europeans were overpowered and Magellan was killed by Lapulapu and his men. Following his death, Magellan was initially succeeded by co-commanders Juan Serrano and Duarte Barbosa (with a series of other officers later leading). The fleet left the Philippines (following a bloody betrayal by former ally Rajah Humabon, who had poisoned many Spanish soldiers on

2325-647: The Pacific, and then reached the Philippines . There, in April 1521, Magellan was killed in the Battle of Mactan . Under the command of captain Juan Sebastian Elcano , the expedition finally reached the Spice Islands. The fleet's two remaining ships then split ways, one attempting, unsuccessfully, to reach New Spain by sailing east across the Pacific. The other , commanded by Elcano, sailed west across

Born c. 1480 into a family of minor Portuguese nobility , Magellan became a skilled sailor and naval officer in service of the Portuguese Crown in Asia. King Manuel I refused to support Magellan's plan to reach the Moluccas , or Spice Islands, by sailing westwards around the American continent. Magellan then proposed

One of them wounded him on the left leg with a large cutlass, which resembles a scimitar, only being larger. That caused the captain to fall face downward, when immediately they rushed upon him with iron and bamboo spears and with their cutlasses, until they killed our mirror, our light, our comfort, and our true guide. Nothing of Magellan's body survived; that afternoon

2550-404: The assassination of the navigator. When Magellan eventually sailed to the open seas in August 1519, a Portuguese fleet was sent after him, though it failed to capture him. Magellan's fleet consisted of five ships carrying supplies for two years of travel. The crew consisted of about 270 men of different origins, though the numbers may vary downwards among scholars based on contradicting data from

Magellan met with the King of Cebu, Rajah Humabon , who asked them for tribute as a trade, thinking they were traders bartering with them. Magellan and his men insisted that they did not need to pay tribute as they were sent by the king of Spain, "the most powerful king in the world", and that they were willing to give peace to them if they wanted peace and war if they wanted war. Humabon then decided not to ask for any more tribute and welcomed them instead to

In Zulu textiles they symbolise a married man, as opposed to a pair of triangles joined at the base, which symbolise a married woman. Neolithic examples can be seen among Spanish cave paintings . Observers have even given the name "hourglass motif" to shapes which have more complex symmetry, such as

2775-426: The bulbs and regulate the pressure within the bulb that varied the flow. While some early hourglasses actually did use silica sand as the granular material to measure time, many did not use sand at all. The material used in most bulbs was "powdered marble , tin / lead oxides, [or] pulverized, burnt eggshell". Over time, different textures of granule matter were tested to see which gave the most constant flow within

2850-411: The bulbs. It was later discovered that for the perfect flow to be achieved the ratio of granule bead to the width of the bulb neck needed to be 1/12 or more but not greater than 1/2 the neck of the bulb. Hourglasses were an early dependable and accurate measure of time. The rate of flow of the sand is independent of the depth in the upper reservoir, and the instrument will not freeze in cold weather.

3000-430: The circumnavigation. Of the 270 men who left with the expedition, only 18 or 19 survivors returned. After several weeks in the Philippines, Magellan had converted as many as 2,200 locals to Christianity, including Rajah Humabon of Cebu and most leaders of the islands around Cebu. However, Lapulapu , the leader of Mactan, resisted conversion. In order to gain the trust of Rajah Humabon, Magellan sailed to Mactan with

In Seville he befriended his countryman Diogo Barbosa and soon married the daughter of Diogo's second wife, Maria Caldera Beatriz Barbosa. They had two children: Rodrigo de Magallanes and Carlos de Magallanes, both of whom died at a young age. His wife died in Seville around 1521. Meanwhile, Magellan devoted himself to studying

King Manuel saw all of this as an insult and did everything in his power to disrupt Magellan's arrangements for the voyage. The Portuguese king allegedly ordered that Magellan's properties be vandalized as it was the coat of arms of the Magellan displayed at the family house's façade in Sabrosa, his home town, and may have even requested

The Chamorro people may have thought they were participating in a trade exchange (as they had already given the fleet some supplies), but the crew interpreted their actions as theft. Magellan sent a raiding party ashore to retaliate, killing several Chamorro men, burning their houses, and recovering

3300-479: The expedition came from the crew of the San Antonio , led by Estêvão Gomes , which deserted the fleet in the Strait of Magellan and returned to Seville 6 May 1521. The deserters were put on trial, but eventually exonerated after producing a distorted version of the mutiny at Saint Julian, and depicting Magellan as disloyal to the king. The expedition was assumed to have perished. The Casa de Contratación withheld Magellan's salary from his wife, Beatriz, "considering

Under questioning by Valladolid's mayor, the men claimed that Magellan refused to follow the king's orders (and gave this as the cause for the mutiny at Saint Julian), and that he unfairly favoured his relatives among the crew, and disfavoured the Spanish captains. One of the few survivors loyal to Magellan was Antonio Pigafetta. Though not invited to testify with Elcano, Pigafetta made his own way to Valladolid and presented Charles with

The next expedition to complete a circumnavigation, led by Francis Drake , was not until 58 years after the return of the Victoria , in 1580. Magellan named the Pacific Ocean (which was sometimes referred to as

Based on the incomplete understanding of world geography at the time, Magellan expected a short journey to Asia, perhaps taking as little as three or four days. In fact, the Pacific crossing took three months and twenty days. The long journey exhausted their supply of food and water, and around 30 men died, mostly of scurvy . Magellan himself remained healthy, perhaps because of his personal supply of preserved quince . On 6 March 1521,

3600-461: The grieving rajah-king, hoping to recover his remains, offered Mactan's victorious chief a handsome ransom of copper and iron for them, but Datu Lapulapu refused. He intended to keep the body as a war trophy. Since his wife and child died in Seville before any member of the expedition could return to Spain, it seemed that every evidence of Ferdinand Magellan's existence had vanished from the earth. In

Because of its symmetry, graphic signs resembling an hourglass are seen in the art of cultures which never encountered such objects. Vertical pairs of triangles joined at the apex are common in Native American art; both in North America, where it can represent, for example,

3750-592: The image of the Child Jesus ( Santo Niño ), which she was drawn to, and begged them for the image in contrition, amidst her tears. Magellan then gave the image of the Child Jesus, along with an image of the Virgin Mary , and a small cross to the queen as a gesture of goodwill for accepting the new faith. The king then had a Blood Compact with Magellan in order to cement the allegiance of the Spaniards and

3825-466: The immediate aftermath of the circumnavigation, few celebrated Magellan for his accomplishments, and he was widely discredited and reviled in Spain and his native Portugal. In Portugal, some regarded Magellan as a traitor for having sailed for Spain. In Spain, Magellan's reputation suffered due to the largely unflattering accounts of his actions given by the survivors of the expedition. The first news of

On 31 March, Magellan's crew held the first Mass in the Philippines , planting a cross on the island's highest hill. Before leaving, Magellan asked the rulers for the next nearest trading ports. They recommended he visit the Rajahnate of Cebu ("Zubu"), because it was the largest. They set off for Cebu , accompanied by

3975-444: The locals. Despite the pleasantries, the first fatal casualty of the expedition occurred. Two months earlier, during the Atlantic crossing, a member of the crew, Antonio Salomon, was caught raping a cabin boy. Tried and found guilty, he was garroted two months later on the shore of Guanabara Bay. From there, they sailed south along the coast, searching for a way through or around the continent. After three months of searching (including

Portuguese and Italian followed with 28 and 27 seamen respectively, while mariners from France (15), Greece (8), Flanders (5), Germany (3), Ireland (2), England and Malaysia (one each) and other people of unidentified origin completed the crew. The fleet left Spain on 20 September 1519, sailing west across

4125-558: The model of the hourglass began to shrink. The smaller models were more practical and very popular as they made timing more discreet. After 1500, the hourglass was not as widespread as it had been. This was due to the development of the mechanical clock, which became more accurate, smaller and cheaper, and made keeping time easier. The hourglass, however, did not disappear entirely. Although they became relatively less useful as clock technology advanced, hourglasses remained desirable in their design. The oldest known surviving hourglass resides in

Mendoza was killed during the conflict, and Magellan sentenced Quesada and Cartagena to being beheaded and marooned, respectively. Lower-level conspirators were made to do hard labor in chains over the winter, but were later freed. During the winter, one of the fleet's ships, the Santiago , was lost in

On 28 March, they anchored off the island of Limasawa ("Mazaua") where they encountered a small outrigger boat ("boloto"). After talking with the crew of the boat via Enrique of Malacca (Magellan's slave-interpreter who was originally from Sumatra ), they were met by

4425-434: The new governor Afonso de Albuquerque , Magellan and Serrão participated in the conquest of Malacca . After the conquest their ways parted: Magellan was promoted, with a rich plunder. In the company of a Malay he had indentured and baptized, Enrique of Malacca , he returned to Portugal in 1512 or 1513. Serrão departed in the first expedition sent to find the " Spice Islands " in the Moluccas , where he remained. He married

The 18 survivors who eventually returned aboard the Victoria in September 1522 were also largely unfavourable to Magellan. Many, including the captain, Juan Sebastián Elcano, had participated in the mutiny at Saint Julian. On the ship's return, Charles summoned Elcano to Valladolid , inviting him to bring two guests. He brought sailors Francisco Albo and Hernándo de Bustamante, pointedly not including Antonio Pigafetta,

The best proof of his genius is that he circumnavigated the world, none having preceded him. Magellan has come to be renowned for his navigational skill and tenacity. The first circumnavigation has been called "the greatest sea voyage in the Age of Discovery ", and even "the most important maritime voyage ever undertaken". Appreciation of Magellan's accomplishments may have been enhanced over time by

In March 1505, at the age of 25, Magellan enlisted in the fleet of 22 ships sent to host Francisco de Almeida as the first viceroy of Portuguese India . Although his name does not appear in the chronicles, it is known that he remained there eight years, in Goa , Cochin and Quilon . He participated in several battles, including the battle of Cannanore in 1506, where he

A number of sandglasses could be fixed in a common frame, each with a different operating time, e.g. as in a four-way Italian sandglass likely from the 17th century, in the collections of the Science Museum, in South Kensington, London, which could measure intervals of quarter, half, three-quarters, and one hour (and which were used in churches, for priests and ministers to measure lengths of sermons).
