Attached to the cathedral is a separate campanile, erected by Giotto and Taddeo Gaddi, A.D., 1334, which consists of five stories, ornamented on the exterior with pilasters, like the cathedral. The three lowermost stories have narrow rectangular windows, the fourth two tiers of pointed win dows, of two lights each, divided by a twisted pillar, and hav ing trefoil heads, and the uppermost one wide pointed win dow of three lights. At the summit is a gallery supported on brackets.
The Pitti palace was designed and partially erected by Brunellcschi, at the close of the fourteenth century. The main body or central portion of the building, is in plan a parallelogram, with a wing projecting at right angles at each extremity ; behind the centre is a small cortile. In eleva tion, the edifice consists of three stories of equal height, each story being somewhat less in frontage than the one below it, so as to give to the whole the appearance of a pyramid, which appearance would have been increased, had the origi nal design been carried out, in which a fourth story was con templated. Each of the stories is of rustic masonry, and crowned by a cornice supporting a gallery with balustrade in front. The windows are placed one above another, and number alike, except in the lower story, where there is only one window under each alternate one above. They are se micircular-headed apertures, and have the voussuirs grooved at the joints. The elevations of the cortile consist of three orders, one to each story ; the lowermost of which is Tuscan, with shafts fluted horizontally. The second order is Ionic, with square blocks ranged at intervals up the and between time columns are semicircular-headed recesses, con taining windows, which have architraves and pilasters on the jambs, and are crowned by pediments; underneath each window is a projecting table, supported by two corbels placed under the architrave. The uppermost order is Corin thian, also with square blocks on the shafts, and between the columns are recesses with horizontal lintels, formed by voussoirs ; within which again is another semicircular headed recess, and windows crowned by a curvilinear pediment.
The Palazzo Strozzi is of rusticated masonry through out the entire facade, in horizontal and vertical channels.
The building consists of three stories ; in the centre of the lowest is a doorway, with semicircular head flanked on each side by three windows having square heads. The windows in the upper story consist of two lights sepa rated by a column. and having half-colutans in the jambs. Both the lights have semicircular heads, and are included undor a coininon semicircular arch. the spandrils of which are filled up with paterte. Each story is separated from the adjoining one by a frieze of (lentils, the entire building being crowned with a plain frieze and boldly pro. jecting cornice, in which both (lentils and modilions are employed.
The nichardi palace consists of three stories, as does the Strozzi palace, which it resembles also in many other fea tures. The lowest story, however, is somewhat peculiar, being formed of uncoursed masonry, with some blocks pro jecting torward beyond the others ; as in the previous exam ple, the doorway is semicircular in the head. The second story is rusticated, and contains seventeen windows in close proximity to each other ; they are of two lights, with a column in the centre, and have semicircula• heads, which enclose the heads of the two light-4, also semicircular. Above these windows is a large surfli.ce of naked wall. above which is a (lentil band, separating this story from that above. The third story is of plain ashlar, and contains windows the same in number and description as those of the second story ; the whole is crowned by a bold cornice.
The church of San Lorenzo, by Brunellesehi, is in plan a Latin cross, the length of which is considerable when com pared with the width ; the height of the building tidlows the same I roportion.4. The body of the church is divided into a central nave with two aisles, by means of an arcade ; the arches of which rest upon Corinthian columns, carrying isolated entablatures, from which the arches spring. At the intersection of the nave and transept, the building is covered by a spherical dome, which stops short ere it meets at the summit, the void so formed being covered by a hemisphere of smaller diameter ; this answers to the lantern more usually applied in such positions.
