The origins of Byzantium are not clear. There is only a legend. It tells that a certain Byzas from Megara (a town near Athens), founded Byzantium, when he sailed northeast across the Aegean Sea. He had asked the Oracle at Delphi where he should found his new city. The Oracle told him to find it "opposite the blind." At the time, he did not know what this meant. But when he came upon the Bosporus he realized what it meant: on the Asiatic shore was a Greek city, Chalcedon. It was they who must have been blind because they had not seen that obviously superior land was just a half mile away on the other side of the Bosporus. Byzas founded his city here in this "superior" land and named it Byzantion after himself.
