lostprofile:EARLY ROMAN TEMPLES Temple of Vesta or of the Sibyl, Tivoli, c. 70 BC Temple of Portunus, Rome, c. 75 BC Four Republican Temples, Rome, Area Sacra del Largo di Torre ArgentinaTemple of Hercules, Cori, c. 80 BCThe surviving temples of the republican period feature some of the early uses of opus caementicium (concrete) for the construction of walls (it had previously been confined to use in foundations and podia) and opus incertum, small, irregularly-shaped stones set into the liquid concrete. The latter functioned as a veneer that sealed the wall from the elements, reinforced the integrity of the wall, and enlived the surface with decorative patterning. -- source link
