Cadmus
Κάδμος
The Phoenician prince said to have founded Thebes and brought Greece its letters.
Searching for his sister Europa, he followed an oracle and founded a city where a cow lay down to rest.
He killed the dragon guarding a spring and sowed its teeth in the earth — armed warriors sprang up, fought each other, and the five survivors became the founding fathers of Thebes.
Herodotus wrote that the Greek alphabet came from Phoenicia through him — and the Greek script really does descend from the Phoenician one.
