W. W. Collins, Cathedral Cities of Italy
“ Elegant turrets with crocketed pinnacles surmounted by saints are on either side of this gable. The two other gables are flanked by towers, each with a solid turret. The purest piece of architecture is the gallery which is between the centre and these two side gables. Below runs a classic frieze separating the upper from the lower part of the façade. The columns and pilasters of the three portals are of white and red marble; they are so heavily laden with elaborate sculpture of beasts, birds, and foliage that they seem to lose their raison d'être and no longer support anything. ”
