In Greek mythology, Eurystheus was king of Tiryns, one of three Mycenaean strongholds in the Argolid, although other authors including Homer and Euripides cast him as ruler of Argos.

The Nemean lion was a monster in Greek mythology that lived at Nemea. Eventually, it was killed by Heracles (Hercules). Because its golden fur was impervious to attack, it could not be killed with mortals' weapons. Its claws were sharper than mortals' swords and could cut through any strong armour. In Bibliotheca, Photius wrote that the dragon Ladon, who guarded the golden apples, was his brother.
