In Greek mythology, Hippocoon was a son of King Oebalus and Queen Gorgophone of Sparta. When their father died, Hippocoon's brother, Tyndareus, became king. Hippocoon overthrew him and took the throne, only to be killed by Heracles, who also killed his son, Lycon and reinstated Tyndareus.
In the Aeneid, Hippocoon participates in the archery contest at Anchises' funeral games. His arrow misses, striking the mast to which the target dove is tied.
Virgil V, 492-545
