Abraxas (, variant form romanized: ) is a word of mystic meaning in the system of the Gnostic Basilides, being there applied to the "Great Archon" (), the princeps of the 365 spheres (). The word is found in Gnostic texts such as the Holy Book of the Great Invisible Spirit, and also appears in the Greek Magical Papyri. It was engraved on certain antique gemstones, called on that account Abraxas stones, which were used as amulets or charms. As the initial spelling on stones was (), the spelling of seen today probably originates in the confusion made between the Greek letters sigma (Σ) and xi (Ξ) in the Latin transliteration.
The seven letters spelling its name may represent each of the seven classic planets. The word may be related to Abracadabra, although other explanations exist.
There are similarities and differences between such figures in reports about Basilides's teaching, ancient Gnostic texts, the larger Greco-Roman magical traditions, and modern magical and esoteric writings. Speculations have proliferated on Abraxas in recent centuries, who has been claimed to be both an Egyptian god and a demon.
Etymology
Gaius Julius Hyginus (Fab. 183) gives Abrax Aslo Therbeeo as names of horses of the sun mentioned by 'Homerus'. The passage is miserably corrupt: but it may not be accidental that the first three syllables make Abraxas.
The proper form of the name is evidently Abrasax, as with the Greek writers, Hippolytus, Epiphanius, Didymus (De Trin. iii. 42), and Theodoret; also Augustine and Praedestinatus; and in nearly all the legends on gems. By a probably euphonic inversion the translator of Irenaeus and the other Latin authors have Abraxas, which is found in the magical papyri, and even, though most sparingly, on engraved stones.
The attempts to discover a derivation for the name, Greek, Hebrew, Coptic, or other, have not been entirely successful:
Egyptian
Claudius Salmasius (1588-1653) thought it Egyptian, but never gave the proofs which he promised. J. J. Bellermann thinks it is a compound of the Egyptian words and , meaning "the honorable and hallowed word", or "the word is adorable". Samuel Sharpe finds in it an Egyptian invocation to the Godhead, meaning "hurt me not".
Hebrew
Abraham Geiger sees in it a Grecized form of , "the blessing", a meaning which Charles William King declares philologically untenable. J. B. Passerius derives it from , "father", , "to create", and negative—"the uncreated Father". Giuseppe Barzilai goes back for explanation to the first verse of the prayer attributed to Nehunya ben HaKanah, the literal rendering of which is "O [God], with thy mighty right hand deliver the unhappy [people]", forming from the initial and final letters of the words the word Abrakd (pronounced Abrakad), with the meaning "the host of the winged ones", i.e., angels. While this theory can explain the mystic word Abracadabra, the association of this phrase with Abrasax is uncertain.
Greek
Wendelin discovers a compound of the initial letters, amounting to 365 in numerical value, of four Hebrew and three Greek words, all written with Greek characters: ("Father, Son, Spirit, holy; salvation from the cross"). According to a note of Isaac de Beausobre's, Jean Hardouin accepted the first three of these, taking the four others for the initials of the Greek , "saving mankind by the holy cross". Isaac de Beausobre derives Abraxas from the Greek and , "the beautiful, the glorious Savior".
Perhaps the word may be included among those mysterious expressions discussed by Adolf von Harnack, "which belong to no known speech, and by their singular collocation of vowels and consonants give evidence that they belong to some mystic dialect, or take their origin from some supposed divine inspiration".
The Egyptian author of the book De Mysteriis in reply to Porphyry (vii. 4) admits a preference of 'barbarous' to vernacular names in sacred things, urging a peculiar sanctity in the languages of certain nations, as the Egyptians and Assyrians; and Origen (Contra Cels. i. 24) refers to the 'potent names' used by Egyptian sages, Persian Magi, and Indian Brahmins, signifying deities in the several languages.

It is uncertain what the actual role and function of Abraxas was in the Basilidian system, as our authorities (see below) often show no direct acquaintance with the doctrines of Basilides himself.
