Hellenism, or Hellenistic Polytheism, consists of a modern pluralistic, polytheistic religion and a related subculture which exists in Greece and in certain communities around the world. It is derived from the beliefs, myths, and rituals of Ancient Greece during the period of classical antiquity. It is a system of thought and spirituality with a shared culture and values, and has a common ritualistic, linguistic, and literary tradition. More broadly, Hellenic Paganism centers itself on the worship of Hellenic deities, namely the twelve Olympians.
