Sardinia

Sardinia was a large island west of Italy and south of the island of Corisca.

According Apollodorus, Iolaus, nephew of Heracles, aided the Heraclids in migrating to Sardinia. These Heraclids were the sons of Thespius' 49 daughters. Thespius was a king of Thespiae, a Boeotian city.

Before Heracles began his labours for Eurystheus, when he was age 18, he was looking after his father's flock (Amphitryon's) at Mount Cithaeron, when he killed a lion (known as the Cithaeron Lion) without a weapon. This deed so impressed the king that he wanted grandchildren from the young hero, and sent his 50 daughters to mate with the young Heracles. One daughter refused to do so, but two of Thespius' daughters had twins, so Heracles had 51 sons. It was these sons who went to Sardinia with Iolaus' help.
