Hesperides the place or ‘garden in which the ‘philosopher’s stone is found. The mythological Hesperian gardens were a favourite symbol in alchemy, because they contained a tree that grew golden apples.
Abraham establishes the Hesperides as the primary alchemical symbol for the locus of the philosopher’s stone, equating the golden apples with the goal of transmutation.
