Epirus or
Epeiros (
Greek: ), in
Greek mythology, is the daughter of
Agave and
Echion. She accompanied
Cadmus and
Harmonia while they were carrying the body of her brother
Pentheus. While in
Epirus, she died and was buried in a thicket; this thicket was later considered sacred to her and the entire country was renamed after her. This same thicket was also considered the place where the king's son Cichyrus accidentally slew a young girl named Anthippe while hunting. In remorse he flung himself into a ravine and was killed. The king's people, the
Chaonians, founded the city of
Cichyrus around the ravine.
