Kometes was one of Meleagros uncles on his mother's side. He took part in the Kalydonian Boar Hunt as well. The hunt ended with Meleagros finally dealing the death blow, but he gave the head to Atlanta for she had drawn first blood. Kometes and his brothers Plexippus and Toxeus were enraged that a woman got the trophy for a hunt which was originally supposed to be all men. Kometes, Plexippus and Toxeus got into a fight and Meleanger. Meleanger killed Kometes as well as Plexippus and Toxeus.
King Thestius and Eurythemis
"On the front gable [of the temple of Athene at Tegea] is the hunting of the Kalydonian Boar. The boar stands right in the center. On one side are Atalanta, Meleagros (Meleager), Theseus, Telamon, Peleus, Polydeukes, Iolaos, the partner in most of the labours of Herakles, and also the sons of Thestios, the brothers of Althaia, Prothous and Kometes. On the other side of the boar is Epokhos supporting Ankaios who is now wounded and has dropped his axe; by his side is Kastor, with Amphiaraus, the son of Oikles, next to whom is Hippothous, the son of Kerkyon, son of Agamedes, son of Stymphalos. The last figure is Peirithoos."
