In Greek mythology, Ialmenus or Ialmenos (/aɪˈælmɪnəs/; Ancient Greek: Ἰάλμενος) was a son of Ares and Astyoche, and twin brother of Ascalaphus.[1] Together with his brother he sailed with the Argonauts, was among the suitors of Helen,[2] and led the Orchomenian contingent in the Trojan War.[3]
Unlike Ascalaphus, Ialmenus survived the war. He was said to have ended up in Colchis, where he founded a colony, the inhabitants of which were later referred to as the "Achaeans of Pontus".[4]
