The Nemean lion (/nɪˈmiːən/; Greek: Νεμέος λέων[1] Neméos léōn; Latin: Leo Nemeaeus) was a vicious monster in Greek mythology that lived at Nemea. It was eventually killed by Heracles. It could not be killed with mortals' weapons because its golden fur was impervious to attack. Its claws were sharper than mortals' swords and could cut through any armor. In Bibliotheca, Photius wrote that the dragon Ladon, who guarded the golden apples, was his brother.[2] Today, lions are not part of the Greek fauna. The Asiatic lion subspecies formerly ranged in southeastern Europe. According to Herodotus, lion populations were extant in Ancient Greece. George Schaller asserts that they may have been present in the area until circa 100 BC.[3]
