The Latin word templum originally referred not to the temple building itself, but to a sacred space surveyed and plotted ritually through augury: "The architecture of the ancient Romans was, from first to last, an art of shaping space around ritual." The Roman architect Vitruvius always uses the word templum to refer to this sacred precinct, and the more common Latin words aedes, delubrum, or fanum for a temple or shrine as a building. The ruins of temples are among the most visible monuments of ancient Roman culture.
