Particular attention should be given to the ceiling, a part of it is divided into four segments with a floral rose window in the centre. A delicious putto appears in each segment, accompanied by an animal closely connected to the pharmaceutical art. The first is a dog, an image of fidelity and related to San Rocco, the patron saint of plague victims. The second is a rooster, which with its crowing awakens and gives life after the torpor of sleep. The third is a snake, traditionally associated with Aesculapius and an image of the drug. The fourth is a turtle, from whose meat therapeutic products were obtained and it is also a symbol of calm and longevity. Each segment is framed by elegant floral decorations that stand out against an intense blue background, creating a chromatic effect.
