The relationship with the classical ideal is fundamental in the painting of Andrea Mantegna, che often depicted portions of ancient buildings, creating a direct link with the precepts of Humanism. This occurs also in the decorations next to the arched doors that give onto the inner courtyard of the House. The marble of the Greek model is transformed into red earth, used for instance by Luca Fancelli to adorn buildings in Mantua. The ideal harmony remains visible to this day, despite the precariousness imposed by the passing of time.
