Lombard columns the Renaissance designer has substituted pilasters, for the plain lintel an entablature, and for the mediæval gable a classic pediment with an entablature.
A curious instance of a somewhat similar composition of lines in a Lombard Romanesque portal without an overhanging porch occurs in the façade of the San Pietro in Cielo d' Oro in Pavia (Fig. 84). Here the arched opening is flanked by tall engaged shafts which carry a narrow string course surmounted by a gable over the crown of the arch, while another string course, on short colonnettes resting on the capitals of the larger shafts, passes over the apex of the gable. But in this case it is only the childish association of members without structural meaning that offends the eye. There is no introduction of forms, like the classic pilasters and entablatures of the portal of Como, that are foreign to the architectural system.

This scheme, with various modifications, became a characteristic one in the Lombard and Venetian Renaissance, and was extensively applied to windows, as in the nave of the same cathedral of Como. The windows of this nave are splayed, and are flanked with pilasters from the capitals of which their archivolts spring, while in some of them diminutive pilasters rise from the same capitals and carry an entablature and pediment over the crown of the arch (Fig. 85).
A variety of forms occur in these openings of the cathedral of Como, like so many experiments in fanciful composition without any basis of reason. The window, for instance, of the bay adjoining that here represented, seems to show that the designer felt dissatisfied with the small pilaster set upon the larger one, and accordingly omitted it, a moulding on the edge of the spandrel, profiled like the lower member of the crowning entablature, taking its place. But again, as if he now felt that the entablature required a more architectural support, he has in another
