T. Roger Smith, Architecture: Gothic and Renaissance
“ At the crossing of the nave and transepts a low dome rises, covered by a conical roof, and surmounted by an elegant marble spire.The structure is vaulted throughout, and each of the great piers which carry the nave arcade is surmounted by a mass of niches and tabernacle work, occupied by statues—a splendid substitute for ordinary capitals. The interior effect of Milan Cathedral is grand and full of beauty. The exterior, though much of its power is destroyed by the weakly-designed ornament with which all the surfaces of the walls are covered, is endowed with a wonderful charm. ”
