In 1999 Egyptologists discovered a series of carving on a piece of rock about 18 by 20 inches. The tableau scene has symbol that may refer to a king named scorpion. The rock shows a figure carrying a staff. Near the head of the figure is a scorpion. Another artifact, a macehead, also shows a king with the scorpion symbol. Both artifacts suggest that Egyptian history may go back to around 3250 B.C. Some scholars believe the scorpion is the earliest king to begin unification of Egypt, represented by the double crown shown.
