When used between antæ or square piers, as seems usually to have been the case in Assyria, the two-fronted form of the Ionic capital was appropriate and elegant; but when it was employed, as in the Erechtheium, as an angle column, it presented a difficulty which even Grecian skill and ingenuity could not quite conquer. When the Persians wanted the capital to face four ways they turned the side outwards, as at Persepolis (Woodcut No. 96), and put the volutes in the angles—which was at best but an awkward mode of getting over the difficulty. The instance in which these difficulties have been most successfully met is in the internal order at Bassæ. There the three sides are equal, and are equally seen—the fourth is attached to the wall—and the junction of the faces is formed with an elegance that has never been surpassed. It has not the richness of the order of the Erechtheium, but it excels it in elegance. Its widely spreading base still retains traces of the wooden origin of the order, and carries us back towards the times when a shoe was necessary to support wooden posts on the floor of an Assyrian hall. Notwithstanding the amount of carving which the Ionic order displays, there can be little doubt of its having been also ornamented with colour to a considerable extent, but probably in a different manner from the Doric. My own impression is, that the carved parts were gilt, or picked out with gold, relieved by coloured grounds, varied according to the situation in which they were found. The existing remains prove that colours were used in juxtaposition, to relieve and heighten the architectural effect of the carved ornaments of this order. In the Ionic temples at Athens the same exquisite masonry was used as in the Doric; the same mathematical precision and care is bestowed on the entasis of the columns, the drawing of the volutes, and the execution of even the minutest details; and much of its beauty and effect are no doubt owing to this circumstance, which we miss so painfully in nearly all modern examples. CORINTHIAN ORDER. As before mentioned, the Corinthian order was only introduced into Greece on the decline of art, and never rose during the purely Grecian age to the dignity of a temple order. It most probably, however, was used in the more ornate specimens of domestic architecture, and in smaller works of art, long before any of those examples of it were executed which we now find in Greece.
