According to a Greek legend, Byzas was a Greek colonist (reported by some to be a leader or even a king) from the Doric colony of Megara in Ancient Greece, consulted the oracle of Apollo at Delphi. The oracle instructed Byzas to settle opposite from the "Land of the Blind". Leading a group of Megarian colonists, Byzas found a superb location opposite Chalcedon on the mouth of the Bosphorus Strait. He determined the Chalcedonians must have been blind not to recognize the advantages the land on the European side of the Bosphorus had over the Asiatic side. Byzas founded Byzantium on the European side in 667 BC, thus completing the oracle's quest.

The name Byzas (Buzas) itself was a Thracian name, and was common among Thracians.
