goddess depicted in the delusional scenes. Most of the paintings were sharing the images of sea as background. Borghini insisted to place Venus, who was holding pearls in her hand standing on a shell. He also set Amphitrite as a marine nymph with coral and amber in the “joyful sea”, which well correspondent to the theme of water. According to Borghini, fire is an “active” element. He decided to bring two muscular figures on the wall. There would also be some scenes that communicate with high temperature. For example, on the upper rectangular canvases of the Studiolo there is a painting named The Woolmaking Factory by Mirabello Cavalori. It vividly depicted the process of wool in cauldrons boiling over high flames. It is no hard to guess that treasures at that time like alum, which is a chemical used treatment of wool would have been kept in the cupboard under this painting. There are two paintings that could most fetch the viewers’ attention. One is that Francesco himself was presented as an alchemist, the prince was depicted at the low right corner following the laboratory procedures in Giovanni Stardano’s painting Il laboratorio dell' Alchimista (The Alchemist’s Studio) (Figure 2), which represents the alchemy within the chamber is fully persistent with a dedicated program expressing the bonds and conjunctions within a living and animate universe, a macrocosm whose affinitive parts can be understood, controlled, and transformed through the intervention of humans. Natural magic and alchemy play unmistakable roles in the Studiolo, and Francesco’s participation is part of a Medici pattern. This painting reasonably tells us the relationship of the Medici and art. They commissioned art by money; meanwhile they were developed from those masterpieces of great artists. This became a powerful statement of the Medici to announce their power and authority in Florence at that time. For the wall of air, there was a young male figure with wings represents the cold wind named Boreas holding a crystal congealed and a female figure Juno, who was regarded as Mrs. Air, the governor of marriage. “Under her jurisdiction came rings, jewels, and precious stones such as diamonds, carbuncles, etc., which were then set into rings.” The other cabinet painting, which Francesco appeared on, is Giovanni Maria Butteri’s La Vetreria (Figure 3).
Francesco shows up in the works merely as a participant in this quest for knowledge. Francesco appears at the painting’s left, examining a goblet produced in the Medici glassworks. Francesco is virtually unnoticed by all but a few of the workers, suggesting the prince as merely an observer of the process of technological creation rather than director or creator of such
innovation. When we move our sight onto the ceiling, we will see exquisite painted frescos about the story of Prometheus receives precious stones from nature in the central panel (Figure 4). It neatly wraps the critical idea of the Studiolo – the interactions between human beings and the dynamic nature. Personifications had been applied in the ceiling frescos in the chamber. The theme of vault frescos communicates that Francesco’s interplay of mythology, nature and humanity, which also echoes to his interest both on art and science. Comparing to the studiolo from the Ducal Palace in Gubbio designed by Francesco di Giorgio Martini for Duke Federico, Duke Federico expressed his wide-ranging interests by putting celebrities from different domains. There were mythological figures, classical philosophers, as well as religious characters. Both of these two studiolos conveyed the idea that the owners of them are well educated and knowledgeable.
