Eteocles

However, because of a curse from their father, the two brothers did not share the rule peacefully and died as a result, ultimately killing each other in battle for control of the city.

The name translates as "truly glorious", from Ancient Greek: ἐτεός eteós “true” and κλέος kleos “glory”.

[2] The name appears in earlier form *Etewoklewes (Ἐτεϝοκλέϝης), attested in Mycenaean Greek tablets as E-te-wo-ke-le-we.

His sons argued over the throne, but Eteocles gained the support of the Thebans and expelled Polynices, who went to Oedipus to ask for his blessing to retake the city, but instead was cursed to die by his brother's hand.

In Hellanicus's account, Eteocles offers his brother his choice of either the rule of the city or a share of the property.
