The Nemean lion was killed by the son of which Greek gods?
Heracles Heracles ( ; Ancient Greek: Ἡρακλῆς , "Hēraklēs", from "Hēra", "Hera"), born Alcaeus (Ἀλκαῖος , "Alkaios") or Alcides (Ἀλκείδης , "Alkeidēs"), was a divine hero in Greek mythology, the son of Zeus and Alcmene, foster son of Amphitryon and great-grandson and half-brother (as they are both sired by the god Zeus) of Perseus. He was the greatest of the Greek heroes, a paragon of masculinity, the ancestor of royal clans who claimed to be Heracleidae (Ἡρακλεῖδαι ), and a champion of the Olympian order against chthonic monsters. In Rome and the modern West, he is known as Hercules, with whom the later Roman emperors, in particular Commodus and Maximian, often identified themselves. The Romans adopted the Greek version of his life and works essentially unchanged, but added anecdotal detail of their own, some of it linking the hero with the geography of the Central Mediterranean. Details of his cult were adapted to Rome as well.
Peneus In Greek mythology, Peneus ( ; Greek: Πηνειός ) was a Thessalian river god, one of the three thousand Rivers (Potamoi), a child of Oceanus and Tethys. The nymph Creusa bore him one son, Hypseus, who was King of the Lapiths, and three daughters, Menippe (mother of Phrastor by Pelasgus), Daphne and Stilbe. He also had a son Atrax with Bura, and Andreus with an unknown consort. Tricce, eponym of the city Tricca, was mentioned as his daughter. Some sources state that he was the father of Cyrene, alternately known as his granddaughter through Hypseus. Daphne, in an Arcadian version of the myth, was, instead, the daughter of the river god Ladon.
