Another feature is, the constant use at all dates of shafts in place of moulded window monials; and another, the very frequent insertion of a transome of tracery, across the middle of the height of the window. The use of the shaft instead of the moulded monial does not seem to be so admirable in ecclesiastical as in domestic work. It generally accompanied the system already mentioned of fixing the glazing in wooden frames, behind the stonework, and hence seldom looks well in church-windows except on the outside. The deep transomes pierced with tracery are of common occurrence. They are seen in almost all the Venetian Gothic churches, but their utility and beauty are alike doubtful. No country affords more frequent examples of circular windows than Italy. They occur in almost every church, and are of stone, marble, and brick. The best example I know, of very early pointed character, and one which is unsurpassed anywhere, is in the west front of the church of Sta. Maria, Toscanella. Here there is an inner wheel, and the space between the two wheels is divided by shafts, between each of which is pierced a quatrefoil. The little window in the gable of the oratory of San Zenone, Verona, is a favourable example of a smaller window. It is of eight lights divided by shafts, and well moulded and proportioned in all its parts. Other circular windows as at S. Mark’s, Venice, and in the church of Sant’Antonio, Padua, are of the class already described, where the tracery seems to have been inserted, without reference to, or connection with, the inclosing circular line.
