Iao or IAO may refer to:
IAO (subtitled Music in Sacred Light) is an album by John Zorn released in 2002 on the Tzadik label. The album was inspired by Aleister Crowley and his follower, filmmaker Kenneth Anger and draws its title from the Kabbalistic identity of IAO, the initials of Isis, Apophis and Osiris, used as a magical formula in the Hermetic Order of the Golden Dawn.
Usage examples of "iao".
I still remember, with a sense of indolent luxury, a picnicing excursion up a romantic gorge there, called the Iao Valley.
Also engraved in minute detail were an invocation in Greek and the names of Oroiouth, Iao, and Yahweh.
