Cassiel

Cassiel ( "Qafṣiʼel"; , ""), (also known as Cafziel, Cafzyel, Caphziel, Casiel, Cassael, Casziel, Kafziel, Kassiel, Kasiel, Qafsiel, Qaphsiel, Qaspiel, Qephetzial, or Quaphsiel), meaning "God is my cover", "Cover of God", "Speed of God" or "God is my anger" 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.
In Jewish mystical literature.
Qaphsiel is invoked in an ancient Hebrew charm to tell if an enemy is running away. Gustav Davidson writes that Qafsiel is described as the ruler of the seventh heaven in 3 Enoch, citing Odeberg's edition. However, Odeberg's edition only states in a footnote that Qafsiel is "(one of) the guardian(s) of the door of the seventh Hall" in "Hekhalot Rabbati". In turn, Qaspiel is described in "Hekhalot Rabbati" as a guardian of the "sixth" palace, armed with a lightning-dripping sword (which shouts "Ruin!") as well as a bow, tempests, light, and powerful winds—weapons which he uses against anyone not fit to see God. Qaspiel is later described in the same work as one of three "guardians of the entrance of the seventh palace," alongside Dumiel and Gabriel. Qaspiel is also listed in "Ma'aseh Merkavah" as a guardian of the "second" palace. "Sefer Raziel" lists Qephetzial as the prince of Saturn. The Zohar describes Kafziel as one of the two chief aides (alongside Hizikiel) to Gabriel.
In western occult literature.
Cassiel is listed in the related works "The Sworn Book of Honorius" and in (pseudo)-Peter de Abano's "Heptameron" (the latter also influenced by "Sefer Raziel"). Cassiel's presence in "Honorius" may also be a result of Greek influence, as he is likewise listed in a Byzantine exorcism manual (as Kasiel). 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 the Sigillum Dei. Following Honorius and the Heptameron, Cassiel appears in the "Liber de Angelis" as Cassael (again the angel over Saturn), then in various editions of the Key of Solomon as Cassiel or Cassael, angel (sometimes archangel) over Saturn or Saturday, and once again in the Sigillum Dei. Cassiel is depicted in Francis Barrett's "The Magus" as a dragon-riding jinn with a beard, again as the angel over Saturn.
Other works.
Cassiel is sometimes described as the angel of tears, the angel of temperance, or the angel who presides over the deaths of kings. As Qafsiel, he is sometimes regarded as the ruler of the moon instead of Saturn.
Averroes and Ibn Arabi likewise listed Saturn as the planetary counterpart of the archangel Kafziel.
Ahmad al-Buni listed Kasfiyail as one of eight angels, among whom each has its own hierarchy of spirits under command.
