Tripus Aureus

Tripus Aureus or The Golden Tripod is an alchemical book by Michael Maier published in 1618 by Lucas Jennis.

It contains three alchemical texts: The "twelve keys" of Basil Valentine, Thomas Norton's Ordinal of Alchemy (1477), and The Testament of Cremer.

It's presented as a sequence of alchemical operations encoded allegorically, in words to which images have been added.

Maier's Latin edition in Tripus aureus contains woodcut illustrations for all twelve keys for the first time.

[2]Cremer's text was also published in Musaeum Hermeticum (1625) and later in Arthur Edward Waite's Hermetic Museum.
