Appears under Sagittarius as a lion's head with five legs radiating from it like the spokes of a wheel. His teaching is medical: moral and natural philosophy, the virtues of every herb and plant, and the cure of all distempers.

Answers out of burning ashes or coals rather than speaking directly, which is unusual even among the seventy-two demons of the Ars Goetia. What he gives is comprehension of things that do not speak: the voices of birds, oxen and dogs, and the sound of running water.

One of the most broadly credited entries in the book — herbs and stones, logic and ethics, invisibility, lost property, hidden treasure, and, alone among the seventy-two, long life. He arrives in plain human shape, which is itself unusual here.

Turns every metal into gold and water into wine, and the wine back into water. The Goetia adds, without elaborating, that he also makes men wise; he appears as a winged bull, then as a man.

Builds houses and high towers and gathers the craftsmen to do it, then dismantles an enemy's desires and thoughts before they can be acted on. A president among the seventy-two demons of the Ars Goetia, he is a crow until he becomes a man, and speaks hoarsely either way.

Inflicts disease and cures it — a pairing almost nothing else in the seventy-two is given, and one that makes his entry read less like a demonology than a physician's. A lion until he chooses to be a man, he also teaches the mechanical arts and changes men's shapes.
