Tradition has it that the raw material for the Greek alphabet was brought to Boeotia by a Phoenician named Kadmos (Cadmus). Kadmos was said to have been the son of the Phoenician king Agenor, and the brother of Europa - whom Zeus set out to seduce, appearing to her in the form of a bull, and whom he eventually carried off. Agenor sent Kadmos off in search of Europa. Having had no luck in finding his sister, Kadmos went to consult the Delphic oracle who told him that he should follow a wandering cow and establish a city wherever she might stop to graze, which he did, and there the Boeotian city of Thebes was established.
