Cadmus

"In Greek mythology, Cadmus (/ˈkædməs/; Greek: Κάδμος Kadmos), was the founder and first king of Thebes. Cadmus was the first Greek hero and, alongside Perseus and Bellerophon, the greatest hero and slayer of monsters before the days of Heracles. A Phoenician prince, son of king Agenor and queen Telephassa of Tyre and the brother of Phoenix, Cilix and Europa, he was originally sent by his royal parents to seek out and escort his sister Europa back to Tyre after she was abducted from the shores of Phoenicia by Zeus. In early accounts, Cadmus and Europa were instead the children of Phoenix. Cadmus founded the Greek city of Thebes, the acropolis of which was originally named Cadmeia in his honour." - (en.wikipedia.org 30.01.2020)
