All the mouldings are very simple; they are generally composed of three-quarter beads, small fillets, and large flat hollows, constantly arranged in the same order. The label of the main arcade is a plain bead. In the string-courses boldly-carved flowers are repeated with a slight interval between each, and the upper string-course has a row of nail-heads in one of its members. The cusping of the tracery is quite square in its section, and the cusps finish with a square end, to which is attached--and with good effect--a small circular ball of red marble. The parapet is of the somewhat peculiar kind I have already mentioned, and I confess I have never been long enough in Venice to accustom myself to, or to admire, its extreme peculiarity of both outline and design. And now before we leave this subject let me offer a remark, as every one who writes on it must, on the admirable story of these sculptures. I have never sat in front of one of them for any space of time without seeing some wayfarer stop to study the story of some one of the capitals. They are a book at which more thousands have looked with pleasure for some five hundred years than at any other single book in the world, with the one exception of the Bible. And the lesson to architects is obvious. Concentrate your labour and your story on some one part of your building where all men may read it; tell some simple story and you will interest your readers, if you will but tell it so simply that by good chance they may be able to read it. Lay out a scheme so well that if you die your successor may carry it on. Here, as I believe, the architect completed his two stages of arcades, whilst the sculptor was changed, but kept generally to the scheme of subjects first of all laid down. At the three exposed angles are the three archangels, below them the moral lesson--as much wanted now as then--of the Drunkenness of Noah, and the Story of Tobit (with S. Raphael); at another angle The Fall (under S. Michael); and at the last the Judgment of Solomon (under S. Gabriel). In the lower range of capitals the stories and catalogues of virtues and vices; the illustrations of fruits, animals, every-day life; the labours of the months, trades, sciences, and arts--are all illustrated, and complete a cycle of subjects which, ill-treated, would always have a certain value, and which, well treated as most of them are here, have the very highest charm.
