Graphiel
Graphiel is a martian Planetary Intelligence which rules over the daemon Barzabel and is in turn ruled by either the Archangel Gabriel or Kamael, depending on the source. His name equals 325 when using Gematria, allowing it to fit on a martian magic square.
Textual History
Graphiel is listed as the Planetary Intelligence of Mars in the second of the Three Books of Occult Philosophy by Agrippa (1533). The same information is copied into MS Harley 6482, published more recently as A Treatise of Angel Magic, from an older document by Thomas Rudd (1583-1656) from around 1699. In Aleister Crowley's Equinox Volume 1, Issue 9 (1913) includes Graphiel in the Evocation of Bartzabel, naming the Archangel Kamael as his ruler. His Magick in Theory and In Practice (1929) also mentions Graphiel, describing him as knowing all there is to know in martial matters, and helpful in little else when performing divination.
