- the Hermetic Order of the Golden Dawn- a magical order active in Great Britain during the late 19th and early 20th centuries, which practiced theurgy and spiritual development. It has been one of the largest single influences on 20th-century Western occultism.
Concepts of magic and ritual at the center of contemporary traditions, such as Wicca and Thelema, were inspired by the Golden Dawn.
Thelema is a spiritual philosophy (referred to by some as a religion that was developed by the early 20th century British writer and ceremonial magician, Aleister Crowley. He came to believe himself to be the prophet of a new age, the Aeon of Horus, based upon a spiritual experience that he and his wife, Rose Edith, had in Egypt in 1904. By his account, a possibly non-corporeal or "praeterhuman" being that called itself Aiwass contacted him and dictated a text known as The Book of the Law or Liber AL vel Legis, which outlined the principles of Thelema.
The Thelemic pantheon includes a number of deities, focusing primarily on a trinity of deities adapted from ancient Egyptian religion, who are the three speakers of The Book of the Law: Nuit, Hadit and Ra-Hoor-Khuit. The religion is founded upon the idea that the 20th century marked the beginning of the Aeon of Horus, in which a new ethical code would be followed; "Do what thou wilt shall be the whole of the Law". This statement indicates that adherents, who are known as Thelemites, should seek out and follow their own true path in life, known as their True Will rather than their egoic desires. The philosophy also emphasizes the ritual practice of Magick.
