Splendor Solis (English: "The Splendour of the Sun") is a version of the illuminated alchemical text attributed to Salomon Trismosin.
It is illuminated on vellum, with decorative borders like a book of hours, meticulously painted and highlighted with gold.
The author of the manuscript was considered to be the legendary Salomon Trismosin, allegedly the teacher of Paracelsus, though the name is believed to be a pseudonym.
The symbolic process shows the classical alchemical death and rebirth of the king, and incorporates a series of seven flasks, each associated with one of the then-known planets.
Within the flasks a process is shown involving the transformation of bird and animal symbols into the Queen and King, the white and the red tincture.
