Hecuba.

Hecuba (Ancient Greek: Ἑκάβη, Hekabē) is a tragedy by Euripides, written c. 424 BC. It takes place after the Trojan War but before the Greeks have departed Troy (roughly the same time as The Trojan Women, another play by Euripides). The central figure is Hecuba, wife of King Priam, formerly queen of the now-fallen city. It depicts Hecuba's grief over the death of her daughter Polyxena and the revenge she takes for the murder of her youngest son, Polydorus.
