Allegory of Divine Providence and Barberini Power (Cortona) Allegory of Divine Providence and Barberini Power (Cortona) The Allegory of Divine Providence and Barberini Power is a fresco by Italian painter Pietro da Cortona, filling the large ceiling of the grand salon of the Palazzo Barberini in Rome, Italy. Begun in 1633, it was nearly finished in three years; upon Cortona's return from Venice, it was extensively reworked to completion in 1639. The Palazzo, since the 1620s, had been the palatial home of the Barberini family headed by Maffeo Barberini, by then Urban VIII, who had launched an extensive program of refurbishment of the city with art and architecture.
Fontana di Piazza Colonna to the foot of the column of Marcus Aurelius. The source of the water for the fountain of Piazza Colonna was only 67 feet above sea level; like the Trevi Fountain, the Fontana della Barcaccia, and the fountains of Piazza Navona, all connected to the Acqua Vergine, the fountain of Piazza Colonna was unable to jet water high into the air. The original project of Della Porta was to place an antique Roman statue of a sea god, called Marforio, in the fountain, against a background of a rocky grotto, behind which the column of Marcus Aurelius would be seen.
