The fascinating St. Jerome in the Wilderness by Leonardo dates back to the second half of the 1400s, and is one of the Pinacoteca's greatest symbols. This work is a middle ground between a painting and a drawing. The figure of the saint being whipped for penance is defined with an accuracy that brings out both the physical and spiritual tension. In the lower left, you can see the outline of the lion that always accompanies the saint in his depictions.
