Eteocles is a name that one would expect to find belonging to a
king, since it means 'true glory', from eteos, 'true', 'real' and cleos, 'glory'. And indeed we find that it was the name of a son of Andreus and
Euippe who was an early king of
Orchomenus in Boeotia, and of a more famous king of Thebes who was the son of
Oedipus and
Jocasta, The latter's brother was
Polynices, and their names indicate clearly who was the 'good' brother and who was the 'bad' one.
