Euhemerus (juːˈhiːmərəs,_-hɛm-; also spelled Euemeros or Evemerus; Εὐήμερος Euhēmeros, "happy; prosperous"; late fourth century BC) was a Greek mythographer at the court of Cassander, the king of Macedon. Euhemerus' birthplace is disputed, with Messina in Sicily as the most probable location, while others suggest Chios or Tegea. The philosophy attributed to and named for Euhemerus, euhemerism, holds that many mythological tales can be attributed to historical persons and events, the accounts of which have become altered and exaggerated over time. Euhemerus's work combined elements of fiction and political utopianism. Early Christian writers, such as Lactantius, used Euhemerus's belief that the ancient gods were originally human to confirm their inferiority regarding the Christian God. Little is known about Euhemerus's life, and his birthplace is disputed. Classical writers such as Diodorus Siculus, Plutarch, and Polybius, maintained that Euhemerus was a Messenian, but did not specify whether he came from the Peloponnesian or the Sicilian Messene, which was an ancient Greek colony. Other ancient testimonies placed his birth at Chios, Tegea (Pseudo-Plutarch, Plac. Phil.), or Agrigentum (Clement of Alexandria, Protrept.; Arnobius, Adv. Gent.). Most modern scholars, however, generally agree that Euhemerus came from the Sicilian Messene (Messina). Diodorus Siculus is one of the very few sources who provide other details about Euhemerus' life. According to Diodorus, Euhemerus was a personal friend of Cassander, king of Macedonia (c. 305 – 297 BC) and the most prominent mythographer for the Macedonian court. Sometime in the early third century BC Euhemerus wrote his main work "Sacred History" ("Hiera Anagraphê"). Only quoted fragments remain from Euhemerus' main work, Sacred History. Diodorus Siculus included fragments from Euhemerus’ writings in the Arabian geography of his fifth book and in the mythology of his sixth book. The sixth book of Diodorus’ Bibliotheca is lost, but Eusebius cites a fragment from it at length in his Praeparatio evangelica.
