other, though often abused, permits full exercise to the imagination: the mind of the sculptor, unshackled by the niceties of chiselling, wanders over its orbed field in endless fantasy; and, when generous as well as powerful, repays the liberty which has been granted to it with interest, by developing through the utmost wildness and fulness of its thoughts, an order as much more noble than the mechanical symmetry of the opponent school, as the domain which it regulates is vaster. [Illustration: Plate XVIII. CAPITALS CONVEX GROUP.] § XL. And now the reader shall judge whether I had not reason to cast aside the so-called Five orders of the Renaissance architects, with their volutes and fillets, and to tell him that there were only two real orders, and that there could never be more.[90] For we now find that these two great and real orders are representative of the two great influences which must for ever divide the heart of man: the one of Lawful Discipline, with its perfection and order, but its danger of degeneracy into Formalism; the other of Lawful Freedom, with its vigor and variety, but its danger of degeneracy into Licentiousness. § XLI. I shall not attempt to give any illustrations here of the most elaborate developments of either order; they will be better given on a larger scale: but the examples in Plate XVII. and XVIII. represent the two methods of ornament in their earliest appliance. The two lower capitals in Plate XVII. are a pure type of the concave school; the two in the centre of Plate XVIII., of the convex. At the top of Plate XVIII. are two Lombardic capitals; that on the left from Sta. Sofia at Padua, that on the right from the cortile of St. Ambrogio at Milan. They both have the concave angle truncation; but being of date prior to the time when the idea of the concave bell was developed, they are otherwise left square, and decorated with the surface ornament characteristic of the convex school. The relation of the designs to each other is interesting; the cross being prominent in the centre of each, but more richly relieved in that from St. Ambrogio. The two beneath are from the southern portico of St. Mark's; the shafts having been of different lengths, and neither, in all probability, originally intended for their present place, they have double abaci, of which the uppermost is the cornice running round the whole façade. The zigzagged capital is highly curious, and in its place very effective and beautiful, although one of the exceptions which it was above noticed that we should sometimes find to the law stated in § XV. above. [Illustration: Fig. LXVI.] § XLII. The lower capital, which is also of the true convex school, exhibits one of the conditions of the spurred type, _e_ of Fig. XXII., respecting which one or two points must be noticed.
