In demonology, Orias (also spelled Oriax) is a Great Marquis of Hell, and has thirty legions of demons under his command. He knows and teaches the virtues of the stars and the mansions of the planets (the influence of each planet depending on the astrological sign in which it is in a specific moment and the influence of that sign on an individual depending on how the zodiac was configured at the moment of his/her birth or at the moment of asking a question to the astrologist); he also gives dignities, prelacies, and the favour of friends and foes, and can metamorphose a man into any shape.
