The Epigoni (, Epigonoi, "progeny") is an ancient Greek tragedy written by the Greek playwright Sophocles in the 5th century BC and based on Greek mythology. According to myth, Polynices and the Seven against Thebes attacked Thebes because Polynices' brother, Eteocles, refused to give up the throne as promised. All but one (Adrastus) of the seven would-be conquerors were killed. Their children swore vengeance and attacked Thebes. This was called the war of the Epigonoi ("the offspring, the next generation"); the story had been told, before Sophocles, in the lost epic Epigonoi. These Epigonoi defeated and killed (or drove out) Laodamas, son of Eteocles, and conquered Thebes, installing Thersander on the throne. All of the Epigonoi but Aegialeus, the son of Adrastus, or else Alcmaeon, son of Amphiaraus, survived this battle. Amphiaraus had known that the attack against Thebes was doomed to fail and had not wanted to partake, but was coerced to do so by his wife Eriphyle, who had been bribed by Polynices. Amphiaraus had instructed his son Alcmaeon to avenge him against his mother, and Alcmaeon killed her, either before or after the war of the Epigonoi, depending on the version of the myth. Alcmaeon was then pursued by the Erinyes, similar to the fate of Orestes after killing his mother Clytemnestra. The play was lost for centuries, except for a few fragments, but in April 2005, classicists at Oxford University, employing infrared technology previously used for satellite imaging, discovered additional fragments of it. The fragment translates to the following: Speaker A: … gobbling the whole, sharpening the flashing iron. Speaker B: And the helmets are shaking their purple-dyed crests, and for the wearers of breast-plates the weavers are striking up the wise shuttle's songs, that wakes up those who are asleep. Speaker A: And he is gluing together the chariot's rail. Several fragments had been definitively assigned to Epigoni prior to this find. One was translated by Hugh Lloyd-Jones as "Most calamitous of sons, what a word have you uttered." This was apparently stated by Eriphyle to Alcmaeon shortly before he killed her. Another fragment has a similar theme: "O woman whose shamelessness has stopped at nothing and has gone yet further, no other evil is or ever will be worse than a woman who was born to give pain to mortals." Another fragment presents an exchange between Alcmaeon and Adrastus, Eriphyle's brother and thus Alcmaeon's
