The Madonna della Pietà (Italian: [pjeˈta]; 1498–1499) informally known as La Pietà is a Roman Catholic dolorous image of Jesus and Mary at Mount Golgotha representing the “Sixth Sorrow” of the Blessed Virgin Mary and a key work of Italian Renaissance sculpture carved by Michelangelo Buonarroti, now enshrined within Saint Peter's Basilica, Vatican City. It is the first of a number of works of the same subject by the Florentine artist. The statue was originally commissioned for a Cardinal of France, Jean Bilhères de Lagraulas, a serving French ambassador in Rome. The Carrara marble sculpture was made for the cardinal's funeral monument, but was moved to its current location, the first chapel on the north side after the entrance of the basilica, in the 18th century. It is the only piece Michelangelo ever signed. This interpretation of the Pietà is unprecedented in Italian sculpture because it balances the Renaissance ideals of classical beauty with naturalism. Pope Urban VIII granted the venerated Marian image a Pontifical decree of canonical coronation via his Papal bull “Domina Coronatum Est” signed and notarized on 14 August 1637 and granted to its patronal donor, Lord Ascanio Sforza y Pallavicini and Canon priest of the Vatican Chapter, Monsignor Ugo Ubaldini. The levitating diadem was manufactured by the Italian artisan, Fantino Taglietti, who charged 564 Italian scudo coins at the time. The official rite of coronation was executed on 31 August 1637. The cherubic angels were added in 1713 by his descendant, later relocated to the “Chapel of the Holy Choir” within the basilica in 1749. The image was significantly vandalized on Pentecost Sunday of 1972 by a rebel fanatic who infiltrated the unsecured altar at the time.
