Fresco cycles were numerous in Cortona's Rome; many represented "quadri riportati" or painted framed episodes imitating canvases as found in the Sistine Chapel ceiling or in Carracci's "The Loves of the Gods" in the Farnese gallery (completed 1601). In 1633, Pope Urban VIII (Maffeo Barberini) commissioned from Cortona a large fresco painting for the main salon ceiling of the Barberini family palace; the Palazzo Barberini. It was completed six years later, following Cortona's influential visit to northern Italy where he would have seen at first hand perspectival works by Paolo Veronese and the colour palette of Titian.
