Tempietto was not intended to stand in a square courtyard; it was to have been surrounded by a circular cloister of 16 columns corresponding to those of the colonnade. When approached through the cloister, the lucidity of the whole radial composition would have been vividly apparent. Moreover, by a subtle ocular effect, the Tempietto world have been made to look higher and wider and more monumental and the surrounding area more spacious. As a result, the sense of harmonious unity created by the concentric composition would have been increased, and with it that elevating and purifying effect required for an Sdeal Christian church.
