The Mutus Liber, or Mute Book (from Latin: Silent Book), is a Hermetic philosophical work published in La Rochelle in 1677. It ranks amongst the major books on alchemy in Early Modern literature, just as much as Atalanta Fugiens by Michael Maier. Nothing further is known about the author.
[Isaac Baulot] Mutus liber in quo tamen tota philosophia hermetica figuris hieroglyphicis depingitur, ter optimo maximo Deo misericordi consecratus, solisque filiis artis dedicatus, authore cuius nomen est Altus. [Geneva, 1702] ➤
