Board game
Board games have been played in most cultures and societies throughout history. A number of important historical sites, artifacts, and documents shed light on early board games such as Jiroft civilization gameboards in Iran. Senet, found in Predynastic and First Dynasty burials of Egypt, c. 3500 BC and 3100 BC respectively, is the oldest board game known to have existed. Senet was pictured in a fresco found in Merknera's tomb (3300–2700 BC). Also from predynastic Egypt is Mehen.
Counting board
The oldest known counting board, the Salamis Tablet ("c." 300 BC) was discovered on the Greek island of Salamis in 1899. It is thought to have been used by the Babylonians in about 300 BC and is more of a gaming board than a calculating device. It is marble, about 150 x 75 x 4.5 cm, and is in the Greek National museum in Athens. It has carved Greek letters and parallel grooves.
