Ars Philtron: Edition Codex Vasculum by Daniel Schulke. 2nd Edition, Revised & Expanded. Xoanon, 2008. Limited to 720 numbered copies, this being #667.
Ars Philtron was the incepting grimoire of the Verdelet of the Cultus Sabbati. Its primary foci are Sabbatic-alchemical gnosis as manifest through the medium of the Potion, and the applications of the principle formulae of Furnace, Vessel, and Water. Its method and praxis concern the principal Sabbatic philtre types, their arcana, pharmacoepia, formulation, and ritual use. As a grammar of the Art Magical, the work instaurates the Philtre as an emanation of the Vinum Sabbati, the manifest elixir of witch-power.
