Through this daughter, Iolaus was considered to have fathered the mythic and historic line of the kings of Corinth, ending with Telestes.

Heracles gave his wife, Megara, age thirty three, to Iolaus, then only sixteen years old[3] – ostensibly because the sight of her reminded him of his murder of their three children.

[5] According to Diodorus Siculus, Iolaus was sent by Heracles to Sardinia, together with nine of the sons that he had with the fifty daughters of Thespius (the Thespiades), to colonize the island, giving rise to the Iolei people.

[7] Simplicius of Cilicia adds, in the eight books of the Commentaries Aristotle, that "the places where they were deposited and preserved corpses of the nine heroes that Heracles got from the Thespians and who came to Sardinia with the colony of Iolaus, became the famous oracles.

[9] The Theban gymnasium was named after Iolaus and the Iolaia or Iolaea (Greek: Ιολάεια), an athletic festival consisting of gymnastic and equestrian events, was held yearly in Thebes in his honor.
