Since the thirteenth century, the Oratory was the seat of the Compagnia dei Disciplinati or dei Bianchi.
On the back wall is the fresco by Perugino depicting the Adoration of the Magi. The work, created in 1504, is among the richest and more ‘crowded’ of the works of this Pievesi Master: history is depicted as a long knightly procession that is lost in the distance in one of the most vast landscapes created by Vannucci.
It is just in this scene that you can recognise that it is a view from Città della Pieve towards Trasimeno and the Val di Chiana and Vannucci inserted characters with the postures and very elegant costumes that echo, in their returning to the ancient statuary, a neo-hellenistic and Virgilian world.
For the colours, the design structure and softness of the depicted landscapes, this work is considered an absolute masterpiece to admire quietly so as not to miss the thousand exquisite details that give harmony to the whole.
