Thoas (son of Jason)
In Greek mythology, Thoas (Ancient Greek: Θόας, "fleet, swift") was a son of Jason and Hypsipyle, and a grandson of the Lemnian king Thoas, and the twin brother of Euneus. Thoas and Euneus took part in the funeral games of the Nemean king Lycurgus' infant son Opheltes, after which they succeeded in rescuing their mother Hypsipyle from her servitude.
