1904 April 8, 9, 10, Egypt, AN4 433

    On April 8, 9, 10, 1904, Aleister Crowley and his wife Rose listened to the voice of a disembodied entity speak for one hour each day between 12pm and 1pm. The resulting manuscript was Liber AL vel Legis, or The Book of the Law.

    For more information on the experience, you can read his account in The Equinox of the Gods. 

    An interesting thing to note is how his wife was able to hear certain words that Crowley was unable to hear, or didn’t recognize.
