In the catalogue tradition preserved in classical sources summarized by modern references, Ialmenus is presented as a son of the war-god Ares and Astyoche and the twin brother of Ascalaphus. He belongs to the generation of heroes associated with pan-Hellenic narratives: he is listed among those who sailed with Jason (the Argonauts), among the suitors of Helen, and as leader of the Orchomenian contingent in the Trojan War. Unlike his twin Ascalaphus, who is recorded as slain at Troy, Ialmenus is said in later tradition to have survived and to have journeyed to Colchis, where he founded a colony whose inhabitants were called the 'Achaeans of Pontus.' (Sources: Apollodorus catalogues as reproduced in the Legendary Passages archives; summarized in modern reference entries including Wikipedia and Citizendium.)
Ancient sources and the catalogic passages that mention Ialmenus provide no specific physical description or distinctive iconography. He is characterized in the sources by patronymic identifiers (son of Ares, brother of Ascalaphus) and by his roles in epic lists rather than by bodily or costume details; the surviving evidence is silent on stature, armor, or other visual markers.
The primary sources treat Ialmenus as a heroic warrior-leader rather than as a supernatural agent. His capacities implied by the tradition are those of an epic-age noble: membership among the Argonauts (a cohort of peer heroes), qualification as one of the suitors of Helen (a high-status noble), and command of the Orchomenian contingent at Troy. No specific magical powers or supernatural faculties are ascribed to him in the supplied materials; his notability rests on genealogy, martial leadership, and his role in foundation-myth narratives (founding a colony in Colchis).

Ares
Ares (Ancient Greek: Ἄρης) is the ancient Greek Olympian god of war who personifies the physical violence, valor, and bloodlust of combat. Worshiped irregularly across Greece and Asia Minor, he was both honored and ritually restrained by communities that sought to direct his martial power toward protection rather than wanton destruction.

Argonauts
A band of human heroes in Greek myth who sailed aboard the ship Argo under Jason to Colchis to retrieve the Golden Fleece. Their identity is defined by membership in the celebrated voyage and by shared heroic lineages; membership lists and details vary by source.
