Il monopteros in Circo Flaminio. Analisi architettonica, tipologica e topografica
During the excavations of the 1930s, a series of fragments of a monument were found in the area of the Teatro Marcello, then recovered in the municipal warehouses and reassembled in the Centrale Montemartini (Capitoline Museums). It is a building with a circular plan and without a cell (monopteros), whose dimensions are well adapted to a circular foundation found in axis with the front of the Temple of Apollo Sosiano.
