Halesus is described by several Latin poets as a bastard son of Agamemnon, and by others as the son of a seer or the kinsman of Agamemnon, after whose death he fled to Italy, whence he is called Agamemnonius, Atries, or Argolicus. He and his wild Auruncans were allied to Turnus. He killed Demodocus, but was killed by Evander.

The foundation of the town of Falisci (Falerii) or Alesium is ascribed to him.
