Borghese was a maternal nephew of Pope Paul V. He wielded enormous power as the Pope's secretary and effective head of the Vatican government, and became very wealthy.[1] In 1607, he began construction of a villa on the Pincian Hill just north of the Pincian Gate in Rome.
The Casino Nobile was less a residence than a retreat for Borghese and his uncle to escape the summer heat of the city and to host receptions for dignitaries. It was also a semi-public museum to house his art collection, including sculptures commissioned from Gian Lorenzo Bernini. Borghese entertained guests in the open loggia on the second floor, where Giovanni Lanfranco painted a large ceiling fresco in quadraturaThe Gods of Olympus also called Council of the Gods.
The Borghese Balustrade was crafted by G di Gincome and P. Massoni in 1618 for the south forecourt of the Casino Nobile. At the center opening there were two stone statues on top and fountains with shell-shaped basins below. The statues were a later addition from 1715 by Claude-Augustin Cayot. In 1896, William Waldorf Astor, former U.S. Minister to Italy, purchased the balustrade and had it installed at his English estate Cliveden. It is a Grade II Listed Building.[5]
Around 1770, Marcantonio Borghese, 5th Prince of Sulmona began recreating the villa as a museum. Old tapestry and leather hangings were removed, new ceiling decorations commissioned and the Casina renovated, according to designs by Antonio Asprucci and his son Mario.[2] Much of the sculpted decorations were done by Vincenzo Pacetti.[6]
