Cadmus, or Kadmos, in Greek mythology, was the son of the king of Phoenicia (Currently Lebanon)and brother of Europa. His father is either Agenor, or Phoenix, son of Agenor. Cadmus founded the city of Thebes, and its acropolis was originally named "Cadmeia" in his honor. Cadmus was credited by the Hellenes with the introduction of the Phoenician alphabet, "phoinikeia grammata" (Herodotus, "Histories" V. 58). Wikipedia
