![]() It was used to measure time observing steady flow of water from or into a container. ![]() Water clock was known to have existed in Babylon in Egypt around 16th Century. This tool of measurement was considered more accurate than the water clock or a candle clock. It could measure passage of specific time period depending upon the size and width of the glass and the quantity of sand in it. The sand-glass/ hourglass, made up of two conical glass connected vertically by the narrow neck, came into being in the 14th Century. The shadows that move to different marks enabled the Egyptians to calculate time which helped to divide day into two parts. In 1500 B.C simple sundials were used to divide the time interval between sunrise and sunset in 12 different parts. The Ancient Egyptian Obelisks, constructed about 3500 B.C was the oldest shadow clock used to measure time. The shortening of shadow would lead to noon while the lengthening of shadows would depict the night approaching. The first instrument to measure time could have been a stick or a mountain. Initially, it was measured by contemplating the nature around us. 9.Time is present alongside human existence on Earth or maybe even before that. Have you ever wondered how was the time measured before clocks were invented? It is said that humans have measured time in different ways in different ages. Yet you can still get the time blasted in your ears at Signal Hill in Cape Town, South Africa, where a cannon is shot at precisely noon each day, a tradition dating to the early 1800s and in Halifax, Nova Scotia, where a noon gun has fired since 1857. Like the time ball, it’s also now obsolete. Similar to a time ball but a lot more cacophonous, the noon cannon is discharged at a specific time (noon) to herald the hour. This "star clock" is known to date to ancient Egypt, and was designed with a long bar and a plumb line, as well as a sighting tool, with which a user could focus on a particular star and use celestial transit as a time marker. Instead of relying just on the sun, it tracked the alignment and visibility of several stars. The merkhet is another ancient solution to the sundial's failure at night. The time ball at the Royal Observatory Greenwich in London falls each day at 1 p.m., just as it has since 1833. Although the Times Square version is really just a novelty-no one starts their midnight clock by it-there are still time balls that operate as nostalgic attractions. By the 1920s, radio and other advancements made them obsolete. The first time ball is considered to have been erected at Portsmouth, England, in 1829 most that followed were also visible from the sea. Rudolf Stielervia Wikimedia Commons // Public domainĮver watched the Times Square Ball drop on New Year’s Eve? You’re witnessing a rare demonstration of time ball timekeeping, a practice that emerged in the 19th century when large metal or wooden balls would plummet at a certain hour to synchronize navigators’ marine chronometers. Sometimes the clock had various colors of smoke to signal the time, others burned to markers or alarms, while a few even involved different incense smells so the user would be olfactorily aware of the passage of time. Although each version involved the burning of incense to track time, the system was often different. ![]() INCENSE CLOCKĭating to the Song dynasty (960-1279), the incense clock spread from China to Japan and other Asian locales. Water clocks appear throughout antiquity, from Egypt to Greece to the Arabic world, and became quite incredible: One 13th century design by Al-Jazari involved a towering water clock on top of a mechanical elephant. The water clock dates to at least 1500 BCE, the basic principle being a device that uses the reliable flow of water to represent the passing of time.
