In Greek mythology, Cleitus (Ancient Greek Κλεῖτος / Κλειτός, "renowned") son of Mantius is a Melampodid whom golden-throned Eos snatched for his beauty before he could grow old. Homer sets him beside his brother Polypheides in Theoclymenus' genealogy for Telemachus; later tradition makes him father of Coeranus and grandfather of Polyeidos.

I.Snatched by Dawn
Homer (Odyssey 15.249–252) pauses on Mantius' two sons: Apollo made Polypheides the greatest seer after Amphiaraus, but Cleitus did not follow into prophecy — Eos the Dawn snatched him for his beauty. Athenaeus and Pherecydes (via scholia) place him among immortals after death; Pherecydes makes him father of Coeranus and grandfather of Polyeidos.
The atlas node is this Melampodid alone.
II.Homonym care
Wikipedia's Cleitus page lists an Aegyptiad bridegroom, a Trojan friend of Polydamas (cleitus-trojan), Thracian kings, and others. Do not merge them with cleitus-melampid.
