Splendor Solis

Definition

Splendor Solis is an illuminated alchemical treatise in German whose 22 paintings picture the stages of the Great Work and end with a rising sun. The best-known copy, Harley MS 3469 in the British Library, is dated 1582; the oldest, in Berlin, dates from the 1530s. Its text is credited to Salomon Trismosin, most likely a pseudonym.

Primary source

This book is named Splendor Solis or Splendour of the Sun and is divided into seven parts. In which is described the hidden mystery of the old Philosophers, as well as all that Nature requires to clearly accomplish the whole Work

Deep Understanding

The treatise announces itself on its own title page: seven parts that set out the hidden mystery of the old philosophers and everything Nature needs to accomplish the Work. The text is a patchwork of authorities. Its preface cites Alphidius, Rhazes, Rosinus and Aristotle's Meteorology, and argues from Aristotle that quicksilver is the matter common to all metals, which is why the philosophers called their matter Mercurius. From there it teaches how the Philosopher's Stone is made, in treatises and parables that quote older alchemical authorities at every turn.

The paintings are what made the book famous. One parable describes a black man stuck fast in foul mud until a crowned woman with peacock-feathered wings dresses him in a purple robe and lifts him to heaven; the painting shows the scene. The centre of the book is a run of seven sealed flasks, each under a planetary god riding in a chariot. Inside the glass a dragon comes first, then birds, a three-headed dragon and a peacock, then a queen, and last a young king dressed in red. The order is usually read as the stages of the work, from nigredo to rubedo. The final painting shows the sun just risen over a city still wrapped in night.

The Trismosin legend grew up around the book. The 1920 English edition calls him the adept and teacher of Paracelsus on its title page, a claim resting on legend alone. Its editor, who signs only as J. K., also proposed that the 22 paintings match the 22 keys of the tarot, and that the text teaches physical alchemy while the pictures teach spiritual alchemy. Those are the editor's readings of 1920, not statements the sixteenth-century manuscript makes about itself. The same introduction repeats the doctrine that metals resolve into salt, mercury and sulphur, the tria prima.

Often confused with

Great Work: the whole alchemical process, which Splendor Solis illustrates as one book among many. Peacock's Tail: a single stage of the work, which appears in one of the flask paintings, where Splendor Solis is the entire sequence.
