Hercules Oetaeus (Hercules on Mount Oeta) is a fabula crepidata (Roman tragedy with Greek subject) of c. 1996 lines of verse which survived as one of Lucius Annaeus Seneca's tragedies. It tells the story of Hercules' betrayal by his jealous wife, Deianira, followed by his death and apotheosis. The general opinion is that the play is not Seneca's, but was written in close imitation.
