Euhemerus (Ancient Greek: Ευήμερος, "happy; prosperous", also transliterated Euemeros or Evemerus; pronounced Evimeros in Modern Greek; late 4th 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 champion Chios or Tegea.
