When in the year 1503 Pope Julius II came to the papal chair, the architect Bramante had recently settled in Rome. Born in Urbino, he had spent his early manhood in the North of Italy, where he had come under the influence of the Florentine architect Alberti at Mantua, and of the early Renaissance masters at Milan and elsewhere. Under these influences he had acquired a style that was peculiar to the North at that time. But since coming to Rome he had begun to form a new manner under the more direct influence of the Roman antique,[36] and he soon developed a style in which the ancient Roman forms were reproduced with stricter conformity to the ancient usage, and with smaller admixture of mediæval features than had before prevailed. An early work in Rome in which he exhibits this more rigorous classic tendency is the small building known as the Tempietto in the cloister of San Pietro in Montorio. It consists of a circular cella with shallow pilasters, surrounded by a colonnade of the Roman Doric order, and surmounted by a hemispherical dome on a high drum. It is thus in form like a Roman temple of Vesta with its dome raised out of the abutting drum and set upon its top without abutment. A glance at Figures 21 and 22, a part section and part elevation of the temple of Vesta at Tivoli, and an elevation of the Tempietto, respectively,[37] will show how great a change Bramante made in the adjustment of the vault to the supporting drum, while it will show also the essential likeness in other points between the two monuments. In Figure 21 it will be seen that the vault is well abutted by the roof of the portico, and by stepped rings of masonry over the haunch, while in Figure 22 the drum is raised high above the encircling portico, and the vault is sprung from its top, and has no abutting rings. The architect appears to have realized that such a scheme would be unsafe on a large scale, for in the one which he prepared for the dome of St. Peter’s he took care, as we shall see, to provide strong abutment. [Illustration: FIG. 21.--Temple of Vesta, Tivoli, from Serlio.] The Tempietto is but a modified copy of an ancient model, and in no true sense an original design. The changes wrought by the copyist are not of a creative kind consistent with true principles of building. The pilasters, and the balustrade with which the order of the portico is crowned, are superfluous, and the work as a whole shows little of Bramante’s real ability as an architect. Such merit as it has is primarily due to the ancient model which he would have done better to have reproduced more exactly. [Illustration: FIG. 22.--San Pietro in Montorio, from Serlio.]
