The first Olympic festival was organized in Elean land, Olympia, Greece by the authorities of Elis in the 8th century BCE, withtradition dating the first games at 776 BCE. The Hellanodikai, the judges of the Games, were of Elean origin.
The local form of the name was Valis, orValeia, and its meaning, in all probability, “the lowland” (compare with the word "valley"). In its physical constitution Elis is similar to Achaea andArcadia; its mountains are mere offshoots of the Arcadian highlands, and its principal rivers are fed by Arcadian springs.
According to Strabo, the firstsettlement was created by Oxylus the Aetolian who invaded there and subjugated the residents. The city of Elis underwent synoikism—as Strabo notes—in 471 BC. Elis heldauthority over the site of Olympia and the Olympic games.
The spirit of the games had influenced the formation of the market: apart from the bouleuterion, which was housed inone of the gymnasia, most of the other buildings were related to the games, including two gymnasia, a palaestrum, and the House of the Hellanodikai.
