Before precision machine parts could be made for clocks, people generally relied on the passage of the Sun through the sky to tell time. Among the most important early devices for telling time were the Egyptian shadow clock, the Greek hemispherium, and the Islamic (modern) sundial. Click on these devices in the illustration to see animations of how the Sun's orientation in the sky was used to mark the daylight hours.

After the Sumerian culture was lost without passing on its knowledge, the Egyptians were the next to formally divide their day into parts something like our hours. Obelisks (slender, tapering, four-sided monuments) were built as early as 3500 B.C. Their moving shadows formed a kind of sundial, enabling citizens to partition the day into two parts by indicating noon. They also showed the year's longest and shortest days when the shadow at noon was the shortest or longest of the year. Later, markers added around the base of the monument would indicate further time subdivisions.
