The Splendor Solis: The 22 Plates of the Alchemical Sun
Among the thousands of alchemical manuscripts that survive, one is famous above all for its beauty. It is the Splendor Solis, "The Splendor of the Sun," a German work of the sixteenth century with twenty-two painted miniatures in rich colors and gold leaf.
People who have seen the pictures often remember them for life: a king emerging from a glass vessel, a bird with a crown, children bathing in a cauldron, a dragon curled on a tomb. The book was made to be looked at, and the images are far clearer than the text. Yet the pictures still keep their secrets.
A Book of Many Copies
The Splendor Solis is not one manuscript, but a family of them. The earliest known copy, now in Berlin, dates from the early 1530s. The best-known and most lavish copy is in the British Library in London, where it is catalogued as Harley MS 3469 and dated to 1582. It was made, according to the usual view, in southern Germany for a wealthy patron. Several other manuscripts and later printings exist, and the pictures differ from one copy to another.
The book is traditionally attributed to Salomon Trismosin, a figure said to have been the teacher of Paracelsus. We do not know whether Trismosin was a real person. Some scholars treat his name as a convenient attribution, similar to the way other alchemical books were put under famous names.
Twenty-Two Treatises
The text is divided into twenty-two parts, called treatises, and each has a picture. The book as a whole takes the Sun, the light that gives life to all things, as a symbol of the Stone and of the perfected substance. The sections present the process of the work in steps, through stages of dissolution, purification and joining, until the final union.
The text itself draws on many earlier alchemical authors and is a compilation. Scholars see it as a compilation of older alchemical sayings, with passages attributed to Hermes and other classic authorities. The text, like those of its kind, is full of riddles. It speaks of "our mercury" and "our fire" and means something that only the author understood.
The Seven Flasks
One of the best-known parts is a sequence of seven flasks, each linked to a planet. In each flask a small figure appears against a backdrop that changes color and mood. The seven stand for a staged transformation, and the order follows the old planetary scheme: Saturn at the beginning, then Jupiter, Mars, the Sun, Venus, Mercury and the Moon, though the text varies.
The flasks are meant to be read as a journey. At the start, the figure is in darkness and black. As the colors change, he is purified, until the last flask shows a radiant figure. It is the same arc as in many alchemical texts: from a dark beginning through a middle of change to a light ending.
Reading the Pictures
Scholars of alchemy emphasize that the pictures were not decorations. They were a second language. A viewer was meant to study each one, noticing the animals, the clothing, the colors and the objects, and to connect them to the text.
Many of the images use traditional symbols: the peacock for the shifting colors that appear in the work, the raven for blackness and decay, the sun and moon for gold and silver, the king and queen for the male and female principles.
Yet no key survives that settles every meaning. Interpretations range from laboratory process to spiritual allegory, and the fairest view is that both were present in the minds of the original readers.
Art for a Patron
A manuscript like this was not cheap. Parchment, gold leaf and the pigments for the miniatures required a skilled workshop, and the cost put the book within reach of princes and wealthy collectors only. In the sixteenth century, alchemy was a respectable interest of courts, and rulers such as Emperor Rudolf II gathered alchemists and their books.
A volume like the Splendor Solis was at once a treatise, a work of art and a sign of its owner's learning.
The quality of the painting explains why the book has outlived most others. Even viewers with no interest in alchemy admire the colors, the landscapes in the background and the care given to small details such as a bird's feathers or the folds of a robe. The images were reproduced in print in modern times, and they have inspired artists, designers and writers.
A Word of Care
The substances named in alchemical books, such as mercury, lead and antimony, are dangerous. The beauty of the pictures should not suggest that the recipes are safe. Nothing in this literature should be tried at home.
Closing
The Splendor Solis is a book that rewards slow looking. Its creators wanted the viewer to feel wonder, and to sense that matter and spirit were not far apart. We may never know exactly what the painters and writers intended, but the images do their work all the same: a golden light, a vessel, and a figure who rises out of dark water into the sun.
