Some ancient authors seem to have considered it a part of the Thebaid and not a separate poem.
[2] It told the story of the last battle for Thebes by the Epigoni, the children of the heroes who had previously fought for the city.
Only the first line is now known: Additional references, without verbal quotations, suggest that the myth of the death of Procris[4] and the story of Teiresias's daughter Manto[5] formed part of the Epigoni.
"[7] This presumably means Antimachus of Teos (8th century BC), and for this reason another verse line attributed without title to Antimachus of Teos is conjecturally thought to belong to the Epigoni.
[8] An alternative explanation for the naming of Antimachus here would be that the later epic poet Antimachus of Colophon (4th century BC) had been accused of stealing the traditional Epigoni by incorporating its plot in his literary epic Thebais.
