Santa Maria del Popolo
The architect or architects of this innovative project remain unknown due to a lack of contemporary sources. Giorgio Vasari in his "Lives" attributed all the important papal projects in Rome during Sixtus IV to a Florentine, Baccio Pontelli including the basilica and monastery of Santa Maria del Popolo. Modern researchers deemed this claim highly dubious and proposed other names among them Andrea Bregno, a Lombard sculptor and architect whose workshop certainly received important commissions in the basilica. The fundamental differences between the façade and the interior suggest that maybe more than one architect was working on the building.
Art patronage of Julius II
The Tomb of Julius II was originally commissioned in 1505, yet was not completed until 1545 on a much reduced scale:One of Pope Julius II’s largest and most well known commissions was the reconstruction of St. Peter’s Basilica, beginning in 1506. When Julius took the papal office, the condition of the Church was extremely poor, and he took the opportunity to expand it, modernize it, and leave his impression forever on the Vatican. Julius hired Donato Bramante to design the Basilica, a prominent architect and artist of the day. This was seen as a surprise move at the time, many thought Giuliano da Sangallo was the front runner for the commission. Della Rovere wanted the splendor of the new basilica to inspire awe in the masses, produce support for Catholicism and prove to his enemies he was a pious and devoted man. Bramante not only would fulfill these expectations with his design, but also with his character, which may explain why della Rovere chose him over Sangallo. “Bramante wanted to build a Basilica that would ‘surpass in beauty, invention, art and design, as well as in grandeur, richness and adornment all the buildings that had been erected in that city’" (Scotti, 47).
