Halirrhothius

Halirrhothius /ˌhælɨˈroʊθiəs/ (Greek: Ἁλιρρόθιος) was the son of Poseidon and Euryte (or Bathycleia^[1]) in Greek mythology. When Halirrhothius raped Alcippe, Ares's daughter by Aglaulus, Ares murdered him; Ares was tried in a court made up of his fellow gods. The trial was held atop the Acropolis of Athens, on what is now known as the Areopagus. Ares was acquitted.^[2]

In another version of the myth, Halirrhothius was sent by his father to cut down the olive that had grown out of the spear of Athena. As he raised his axe, it fell out of his hand and mortally wounded him. The olive was called "fatal" from that circumstance.^[3]
