other. Thus, in the junction of the circles of the window of the Palazzo Foscari, Plate VIII, given accurately in fig. 8, Plate IV, the section across the line s, is exactly the same as that across any break of the separated moulding above, as s. It sometimes, however, happens, that two different mouldings meet each other. This was seldom permitted in the great periods, and, when it took place, was most awkwardly managed. Fig. 1, Plate IV, gives the junction of the mouldings of the gable and vertical, in the window of the spire of Salisbury. That of the gable is composed of a single, and that of the vertical of a double cavetto, decorated with ball flowers; and the larger single moulding swallows up one of the double ones, and pushes forward among the smaller balls with the most blundering and clumsy simplicity. In comparing the sections it is to be observed that, in the upper one, the line a b represents an actual vertical in the plane of the window; while, in the lower one, the line e d represents the horizontal, in the plane of the window, indicated by the perspective line d e.
XXVII. The very awkwardness with which such occurrences of difficulty are met by the earlier builder, marks his dislike of the system, and unwillingness to attract the eye to such arrangements. There is another very clumsy one, in the junction of the upper- and sub-arches of the triforium of Salisbury; but it is kept in the shade, and all the prominent junctions are of mouldings like each other, and managed with perfect simplicity. But so soon as the attention of the builders became, as we have just seen, fixed upon the lines of mouldings instead of the enclosed spaces, those lines began to preserve an independent existence wherever they met; and different mouldings were studiously associated, in order to obtain variety of intersectional line. We must, however, do the late builders the justice to note that, in one case, the habit grew out of a feeling of proportion, more refined than that of earlier work-
