Transmission of Arabic Astrology to Latin Europe and Its Marginal Demonological Reception
Aben-Ragel (Arabic: أبو الحسن علي بن أبي الرجال, Abū al-Ḥasan ʿAlī ibn Abī al-Rijāl) was an 11th-century Arab astrologer born in Córdoba, in the region of al-Andalus. His full name is frequently Latinized as Abenragel, Avenragel, or Albohazen Haly, reflecting multiple transliteration forms used in European manuscripts and early printed books. He is primarily known for his treatise on astrology, originally composed in Arabic and later translated into Latin under the title De judiciis astrorum or De judiciis seu fatis stellarum.
Absence from Canonical Demonological Texts
Aben-Ragel does not appear in major Western demonological sources such as the Lemegeton Clavicula Salomonis, Pseudomonarchia Daemonum, Dictionnaire Infernal, or the Book of Abramelin. He is likewise not included in earlier Christian demonological catalogues such as those compiled by Honorius of Thebes or Johann Weyer. There is no evidence suggesting he was ever classified as a demonic entity, spirit, or magical being in any historical occult system.
Confusion with Magical or Occult Sources
Despite his absence from demonological literature, Aben-Ragel’s astrological work entered the European esoteric tradition, particularly through translations commissioned by Alfonso X of Castile and printed editions such as the Venice 1485 version of De judiciis. Due to the close ties between astrology, natural philosophy, and occult practices during the late Middle Ages and Renaissance, his name occasionally appears in bibliographies of occult literature or on the periphery of texts dealing with ritual magic or celestial influences.
However, there is no documentation suggesting that Aben-Ragel’s identity was ever conflated with any supernatural figure, nor is there any attested iconography, sigil, invocation, or role within ritual practices of demon summoning attributed to him. Mentions of Aben-Ragel in magical grimoires—when present—are limited to astrological tables or theoretical knowledge borrowed from his treatise, not references to him as an operative spirit.
Possible Causes of Misclassification
References to “Abenragel” in modern occult bibliographies may result from:
- Misinterpretation of authorial names in magical texts.
- Copyist or printer errors in Renaissance compilations where names were abbreviated or misunderstood.
- Thematic association of astrology with forbidden arts, leading to a generalized categorization of astrological authors under occult or magical classifications by later Christian critics.
These misreadings may have contributed to occasional listings of Aben-Ragel in 19th- or 20th-century occult encyclopedias, despite the absence of any doctrinal or ritual role as a demon.
Legacy and Transmission
Aben-Ragel’s original Arabic treatise, titled Kitāb al-bāriʿ fī aḥkām an-nujūm, was a foundational work in the Islamic science of judgments (ahkam). The Latin translation, often attributed to Johannes Hispalensis or Judah ben Moses ha-Cohen, was widely disseminated during the 13th to 15th centuries and became influential in medieval European astrology. His work reflects the rational and observational focus of Islamic astrology, rather than any mystical or demonological content.
