420 ST. MARK’S, VENICE

been, first, those caused by the insertion of the lamps themselves, and then the breaking away of the marble network of the main capital by the habitual clattering of the said gaslighter’s ladder against it. A piece of it which I saw so broken off, and made an oration over to the passers-by in no less broken Italian, is in my mineral cabinet at Brantwood.

10. Before leaving this subject of the inclined angle, let me note-usefully, though not to my present purpose- that the entire beauty of St. Mark’s Campanile depends on this structure, there definitely seen to be one of real safety. This grace and apparent strength of the whole mass would be destroyed if the sides of it were made vertical. In Gothic towers, the same effect is obtained by the retiring of the angle buttresses, without actual inclination of any but the coping lines.
