 Other sources make him a son of Cephalus.Aristotle in his lost work "The State of the Ithacians" cited a myth according to which Cephalus was instructed by an oracle to mate with the first female being he should encounter if he wanted to have offspring; Cephalus mated with a she-bear, who then transformed into a human woman and bore him a son, Arcesius.Hyginus makes Arcesius a son of Cephalus and Procris, while Eustathius and the exegetical scholia to the "Iliad" report a version according to which Arcesius was a grandson of Cephalus through Cillus or Celeus.
