Algorab is counted among the fifteen Behenian fixed stars, a set of prominent stars singled out in medieval and Renaissance astrological magic as carrying particularly concentrated occult influence, useful for the specific kind of talismanic work that tradition described. The list was compiled in the Arabic and Latin magical literature of the medieval period, most influentially transmitted through the Picatrix, and was repeated with additional detail in the sixteenth century by Heinrich Cornelius Agrippa in his Three Books of Occult Philosophy, whose tables paired each of the fifteen stars with a planetary nature, a sigil, and, in fuller versions of the tradition, a corresponding plant and stone thought to draw on the same influence.
Compilations of this material, including Vivian Robson's widely cited twentieth century survey The Fixed Stars and Constellations in Astrology, gather the scattered classical and medieval attributions given to each of the fifteen stars into a single reference, though the specific correspondences recorded for any one star can vary somewhat between sources depending on which manuscript tradition a given compiler worked from.
Algorab's place on the list reflects Corvus's long standing prominence in the older astrological literature generally, well beyond the fixed star tradition specifically, since the constellation's mythic association with false speech and broken oaths made it a frequently cited figure in judicial and predictive astrology dealing with deception and testimony.
