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.

The altar was executed by stonemason Gabriele Renzi around 1658. The altarpiece for the left side altar was entrusted to Bernardino Mei, a painter from Siena, who was called to Rome by Pope Alexander VII in 1657 and there he made friends with Bernini. He got 200 scudi for the commission on 11 August 1659. The painting is perfectly adapted to the Berninian ideal of «bel composto». The angel on the right is gracefully aligned with the marble angel supporting the altar. The iconography of the painting is rather complex and departs from the usual representation of the Rest on the Flight into Egypt.
