Textual history
Zuriel is mentioned in many grimoires from the 1500s onward. His name first appears in print in Three Books of Occult Philosophy (1531), but must have come from an older, unidentified source. The Magical Calendar (1619) marks the earliest publication of his summoning seal. Arsenal Manuscript 2495 (1600s) contains the earliest known explanation of the angel's abilities, although this text likely utilized an older source. Additionally, MS Harley 6482, published more recently as A Treatise of Angel Magic, from an older document by Thomas Rudd (1583-1656) around 1699 also features the spirit. This was in turn copied by John Heydon in his book Theomagia (1663). Here he is placed under the rulership of Kedemel.
