Twins in mythology upon. However, other cultures attribute the outcome of twins to superior virility of the father. In various mythologies, twins often represent the dualistic nature of the universe. In Greek mythology, twins Apollo and Artemis, are the sun god and moon goddess, respectively. Similar forms of higher beings are reflected throughout different mythologies, as twin brothers Kuat and Iae represent the sun and moon in the Xingu mythology of Brazil. Egyptian God, Geb, and his twin sister, Nut, represented the binary nature of the world, with Geb being the God of the Earth, and Nut being the Goddess of the sky.
Apollo god, and his elevation to an intellectual sphere, may be considered an achievement of the Greek people. The function of Apollo as a "healer" is connected with Paean (), the physician of the Gods in the "Iliad", who seems to come from a more primitive religion. Paeοn is probably connected with the Mycenean "pa-ja-wo-ne" (Linear B: ), but this is not certain. He did not have a separate cult, but he was the personification of the holy magic-song sung by the magicians that was supposed to cure disease. Later the Greeks knew the original meaning of the relevant song "paean"
