伊露維塔
The supreme deity of Tolkien's universe is Eru Ilúvatar. Ilúvatar created spirits named the Ainur from his thoughts, and some were considered brothers or sisters. Ilúvatar made divine music with them. Melkor, then the most powerful of the Ainur, broke the harmony of the music, until Ilúvatar began first a second theme, and then a third theme, which the Ainur could not comprehend since they were not the source of it. The essence of their song symbolized the history of the whole universe and the Children of Ilúvatar that were to dwell in it—Men and Elves.
