One of Dalí's most incredible series of graphic works is an artist's book entitled Alchimie des Philosophes, or Alchemy of the Philosophers. Created in 1976, it contains ten prints encased in a large portfolio box with ancient alchemical texts from the 3rd-17th centuries reproduced in facsimile. The prints are 56 x 76 cm, and were created with a combination of intaglio, lithography, and serigraphy. There are 275 copies of Alchimie des Philosophes, some in French and English, and some in French and Italian. Each of the prints represents a particular alchemical theme and relates to the ancient texts. The iconography combines Dalí's personal motifs with the symbolism of thousands of years of alchemy.
