The Sixty-second Spirit is Volac, or Valak, or Valu.
Goetia – S. L. MacGregor Mathers (1904) (quoted)
The Sixty-second Spirit is Volac, or Valak, or Valu. He is a President Mighty and Great, and appeareth like a Child with Angel’s Wings, riding on a Two-headed Dragon. His Office is to give True Answers of Hidden Treasures, and to tell where Serpents may be seen. The which he will bring unto the Exorciser without any Force or Strength being by him employed. He governeth 38 Legions of Spirits, and his Seal is thus.
Pseudomonarchia daemonum – Johann Wier (1583) (quoted)
Valac is a great president, and commeth abroad with angels wings like a boie, riding on a twoheaded dragon, he perfectlie answereth of treasure hidden, and where serpents may be seene, which he delivereth into the conjurors hands, void of anie force or strength, and hath dominion over thirtie legions of divels.
Dictionnaire Infernal – Collin de Plancy (1863) (paraphrased)
Volac is high-president of hell and commands 30 legions. He appears as a child with angel’s wings and riding on a two-headed dragon. He tells of the positions of the planets and where to find serpents.
Even today, he’s often invoked by magical practitioners who are looking to find “true answers of hidden treasures”. He’s also known as being quite strong and not opposed to sharing that strength with those worthy of calling upon him. Not worthy? Well then, I’d hate to be you, because Valak will probably ruin your life.
