Editing Iolaus (section)

===Adventures===
Iolaus provided essential help to Heracles in his battle against the [[Lernaean Hydra|Hydra]], his second [[The Twelve Labours|labor]]. Seeing that Heracles was being overwhelmed by the multi-headed monster (the Lernaean Hydra), who grew two heads in place of each one cut off, Iolaus helped by [[Cauterization|cauterizing]] each neck as Heracles beheaded it.

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.<ref>[[Diodorus Siculus]], book IV, 29–30.</ref>

Iolaus and the Thespians were buried in Sardinia.{{Citation needed|date=March 2025}}

[[Aristotle]] said that Sardinia had practiced the rite of [[Incubation (ritual)|incubation]], which is the liberation ritual of the people who were affected by [[nightmares]] and obsessions. These rituals included that the persons suffering from nightmares should sleep next to the tombs of heroes.<ref>[[Aristotle]], ''[[Physics (Aristotle)|Physics]]'', IV.</ref>

[[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."<ref>Simplicius, book IV.</ref>

[[Gaius Julius Solinus|Solinus]] says: "The [[Iolei|Iolians]], so named by him (Iolaus), added a temple to his tomb, because he had freed Sardinia from many ills".<ref>[[Gaius Julius Solinus|Solinus]], I-16:'' Iolenses ab eo dicti sepulcro eius templum addiderunt quod ... Malis plurimis Sardiniam liberasset''.</ref>
