The Trachiniae

Women of Trachis or The Trachiniae c. 450–425 BC, is an Athenian tragedy by Sophocles. Women of Trachis is generally considered to be less developed than Sophocles' other works, and its dating has been a subject of disagreement among critics and scholars.
Sophocles is one of three ancient Greek tragedians whose plays have survived. His first plays were written later than or contemporary with those of Aeschylus, and earlier than or contemporary with those of Euripides.
