the arched type, in which a column divides the opening vertically and sup ports the ends of two smaller arches under a main rusticated arch, as in the upper stories of the Riccardi Palace; the arcltitrave type; where the sections of the openings are molded and a pediment, or cornice, supported on consoles covers the top, as in the lower story of the Riccardi Palace; and the columnar type, where a column, or pilaster, flanks each side of the opening and supports an entablature, or pediment, as in the Panclolfini Palace (International Textbook, 1922)
