Pope Innocent XIII is depicted in a camauro cap, mozzetta, and wide stole with tendril motifs and the symmetrically repeated coats of arms of the Conti family, with tiara and keys. The sculpture was attributed to Pietro Bracci based on stylistic traits. The sculptor may have made the Pope’s posthumous portrait based on a known likeness of Innocent XIII painted by Agostino Masucci. The bust may have been commissioned by his nephew, Stefano dei Conti. The sculpture was formerly in the Palazzo Albani in Rome, then the Palazzo del Drago, Rome; identified by Andrzej Ciechanowiecki in a private collection in the UK in the 1970s. 1980 – gift of the Federal Republic of Germany to the Royal Castle in Warsaw.
