Ancient Egyptian Sun Dial Found
"During archaeological excavations in the Kings' Valley in Upper Egypt a team of researchers from the University of Basel found one of the world's oldest ancient Egyptian sun dials. The team of the Egyptological Seminar under the direction of Prof. Susanne Bickel made the significant discovery while clearing the entrance to one of the tombs. During this
year's excavations the researchers found a flattened piece of limestone (so-called Ostracon) on which a semicircle in black color had been drawn. The semicircle is divided into twelve sections of about 15 degrees each. A dent in the middle of the approximately 16 centimeter
long horizontal baseline served to insert a wooden or metal bolt that would cast a shadow to show the hours of the day. Small dots in the middle of each section were used for even more detailed time measuring. The sun dial was found in an area of stone huts that were used in the 13th century BC to house the men working at the construction of the graves.
