If in fact medieval churches were based on the principles of man's immensely small position in the face of the infinite magnificence of the divine and to this end favored in the construction of the vertical pattern and size, the Renaissance buildings were transformed on the contrary to represent a space on a human scale, practicable and rational in which harmony triumphs. Indeed, in the buildings designed and constructed by Filippo Brunelleschi it is always possible to trace the architectural application of geometric principles such as symmetry and balance of composition, obtained through the rhythmic repetition of constructive or decorative modules. Among the architectural elements derived from Roman buildings, were introduced in the central plan (in the temple of S.Pietro in Montorio de Bramante), in the barrel (in the Cappella Pazzi d'Alberti), in the coffered dome as in the Pantheon ( inside S.Andrea de Mantua by Alberti), the columns of different styles (in San Lorenzo by Brunelleschi and the Venetian churches made by Colucci).
