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

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

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,

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

While exploring the strait, one of the remaining four ships, the San Antonio , deserted

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."

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

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 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 ");

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

Sand timers are sometimes included with boardgames such as Pictionary and Boggle that place time constraints on rounds of play.

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

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 .

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

While some early hourglasses actually did use silica sand as the granular material to measure time, many did not use sand at all.

Over time, different textures of granule matter were tested to see which gave the most constant flow within

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.

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,

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.
