Ithiel (Hebrew אִיתִיאֵל) is an enigmatic name mentioned in the Biblical verse of Proverbs 30:1. The name is angelic in origin, having the Hebrew -suffix Yodh, Aleph, Lamed, and can have a number of meanings. The name, Ithiel, has as its root a variation of the word “ot” meaning sign and can be rendered as “the words of God,” “he who understood the signs,” or “he who understood the alphabet of God,” relating to the letters of the Hebrew alphabet, the root word “ot” also signifying “letters.”
The Irish abbot and missionary Saint Columba mentions Ithiel, along with Uriel, as one of seven angels charged with taking care of a monastery in his ode Farewell.
Arthur Cleveland Coxe, in his book Advent: a Mystery, treats Ithiel as an angel in conversation with the counterpart Adiel and writes into them dialogue as in the form of a play.
Charles Morgridge has described the angel Ithiel as “prince of the seventh or lowest order of the hierarchy of heaven” and of being the weight of judgment for the men of God.
In Hebrew Gematria Ithiel is 452 which has an exact correspondence to the Greek words meizonos and krithete , which, when placed together mean “great judge.”
The occultist Arimanius Théletos, who created the Magic Square of Ithiel, has used it to derive an evocation of Ithiel that can be used in magic ritual. The words of the evocation are Hebrew renderings of phrases drawn from the Magic Square of Ithiel. It begins with the palindrome “le-Ithiel” , meaning “to Ithiel” which can be read along each side of the magic square. Other phrases such as “Abba” (father) and “yomar” (he will say) are also encoded within the cryptic message of the cipher. Each other palindrome inside the magic square form barbarous names, which are corrupted names of deities particularly used in magical evocations. According to Rosemary Guiley barbarous names are used “to command all spirits of the firmament, ether, and the elements.”
Due to the nature of the magic square each phrase can be read in four different directions. The evocation attributed to Arimanius Théletos has been rendered from Hebrew to English thus:
L'BAMAOMABAL L'ITIEL,
ABATzABA YOMARAMOY,
TATzARO'ORATzATA, TATzARO'ORATzATA
L'BAMAOMABAL, L'BAMAOMABAL
TATzARO'ORATzATA, TATzARO'ORATzATA
YOMARAMOY ABATzABA,
L'ITIEL L'BAMAOMABAL.
