This scene takes place in 1553: the Duke is seated in front of a model and map of Siena, as he studies a way to conquer the city. Around him are his Virtues: on the left are Patience (with an urn) and Vigliance (with candle-light), on the right are Prudence (with a mirror and snake), Fortitude (armed and resting against a column) and Silence (with hand on mouth).
