Panteón de Agripa
The wall between the Corinthian columns is pierced with rectangular aedicule windows, topped by alternating [[curvilinear]] and triangular [[Tympanum (architecture)|tympanum]]s. The solution of the alternating tympanums had been employed by both [[Bramante]] and [[Raphael]] for residential architecture and by Palladio for [[Palazzo Porto, Vicenza|Palazzo Porto]] and [[Palazzo Chiericati]]. Palladio also proposed the combination in his design for the rebuilding of the Doge's Palace after the fire of 1577, which may have been the immediate source for Scamozzi. The ancient prototype is the [[Pantheon, Rome|Pantheon]] where the altars alternate around the perimeter, in pairs, with curvilinear and triangular pediments. Scamozzi's design for the upper floor included elaborate carvings and reclining figures atop the tympanums. But these were eliminated from the design by Smeraldi and exist only above the first ten windows, completed during Scamozzi's superintendence.
