Ancient Egyptian Sundial Discovered

A sundial discovered outside a tomb in Egypt's Valley of the Kings may be the world's oldest ancient Egyptian sundials, say scientists.
Dating to the 19th dynasty, or the 13th century B.C., the sundial was found on the floor of a workman's hut, in the Valley of the Kings, the burial place of rulers from Egypt's New Kingdom period (around 1550 B.C. to 1070 B.C.).

"The significance of this piece is that it is roughly one thousand years older than what was generally accepted as time when this type of time measuring device was used," said researcher Susanne Bickel, of the University of Basel in Switzerland. Past sundial discoveries date to the Greco-Roman period, which lasted from about 332 B.C. to A.D. 395.
