Evelyn-White, The Ionic School of Epic poetry

What links bound the “Titanomachy” to the Theben Cycle is not clear. This latter group was formed of three poems, the “Story of Oedipus”, the “Thebais”, and the “Epigoni”. Of the “Oedipodea” practically nothing is known, though on the assurance of Athenaeus (vii. 277 E) that Sophocles followed the Epic Cycle closely in the plots of his plays, we may suppose that in outline the story corresponded closely to the history of Oedipus as it is found in the “Oedipus Tyrannus”. The “Thebais” seems to have begun with the origin of the fatal quarrel between Eteocles and Polyneices in the curse called down upon them by their father in his misery. The story was thence carried down to the end of the expedition under Polyneices, Adrastus and Amphiarus against Thebes. The “Epigoni” (ascribed to Antimachus of Teos) recounted the expedition of the ‘After-Born’ against Thebes, and the sack of the city.
