Fergusson's "History on the Modern Styles of Architecture," p. 243. The Pantheon at Rome as restored A.D. 202 was, or rather is, a rotunda with a portico. The rotunda, according to Fergusson ("Handbook," p. 311), is about 125 feet in internal diameter, and an external elevation of about 150 feet. The Basilica of Maxentius, or Temple of Peace, may have been finished in the reign of Constantine (Maxentius, A.D. 311-312; Constantine the Great, 325-337). The ruins show an oblong of 265 feet by 195 feet in internal measurement, including aisles. The whole length is divided into only three bays ("Handbook," p. 319). Fergusson should have added St. Peter's at Rome, which exercised such an influence over Wren. This immense building has, in the exterior, only one Order and an Attic. All three have the round arch.
