Cassiel
Cassiel (Hebrew: קַצְפִּיאֵל, "God is my wrath") is an angel appearing in extracanonical Jewish, Christian, and Islamic mystical and magical works, often as one of the Seven Archangels, the angel of Saturn, and in other roles.
Cassiel is sometimes described as the angel of tears and the angel of temperance. He is sometimes conflated with Archangel Zaphkiel.
Abilities
Cassiel is invoked in an ancient Hebrew charm to tell if an enemy is running away.
He is called the ruler of the seventh heaven in The Book of Enoch, but is only one of three guardians of the door of the seventh Hall.
The Sefer Raziel HaMalakh lists Cassiel as the prince of Saturn. The Zohar describes him as one of the two chief aides (alongside Hizqiel) to Archangel Gabriel. He is one of the angels of death in Judaism; specifically the angel who presides over the deaths of young men.
Cassiel is listed in the related works The Sworn Book of Honorius and in Peter de Abano's Heptameron. Cassiel's presence in Honorius may also be a result of Greek influence, as he is likewise listed in a Byzantine exorcism manual. In these works, he is, as usual, listed as the angel of Saturn but also as the angel of the North and as one of the angels named in John Dee's Sigillum Dei.
In various editions of the Key of Solomon as Cassiel or Cassael, he is the angel (sometimes archangel) over Saturn or Saturday.
Cassiel is depicted in Francis Barrett's The Magus as a dragon-riding Djinn with a beard as the angel over Saturn.
