Input (grade 10): This feature was maintained in the ultimate design. Bramante's dome was to be surmounted by a lantern with its own small dome but otherwise very similar in form to the Early Renaissance lantern of Florence Cathedral designed for Brunelleschi's dome by Michelozzo.
Output (grade 11): Another idea that Bramante got from Florence Cathedral was the design for the little stone tower which sits on top of the dome and is called the lantern.
