A second Pelagon is given in the Iliad as the father of the Paeonian warrior Asteropaeus, son of the river-god Axius and Periboea. Presumably this Pelagon was the eponymous founder of Pelagonia.
A different Pelagon in the Iliad is an "illustrious" companion of Sarpedon, who removes Tlepolemus' spear from Sarpedon's thigh.Homer. Iliad. V:695.
