The Apollo Belvedere or Apollo of the Belvedere, also called the Pythian Apollo, is a celebrated marble sculpture from Classical Antiquity. It was rediscovered in the late 15th century, during the Renaissance. From the mid-18th Century, it was considered the greatest ancient sculpture by ardent neoclassicists and for centuries epitomized ideals of aesthetic perfection for Europeans and westernized parts of the world.
The lower part of the right arm and the left hand were missing when discovered and were restored by Giovanni Angelo Montorsoli (1506-63), a sculptor and pupil of Michaelangelo.
Once it was installed in the Cortile, however, it immediately became renowned and a demand for copies of it arose. The Mantuan sculptor Pier Jacopo Alari Bonacolsi, called "L'Antico", made a careful wax model of it, which he cast in bronze, finely finished and partly gilded, to figure in the Gonzaga collection, and in further copies in a handful of others. Albrecht Dürer reversed the Apollo's pose for his Adam in a 1504 engraving of Adam and Eve, suggesting that he saw it in Rome. When L'Antico and Dürer saw it, the Apollo was probably still in the personal collection of Giuliano della Rovere, who, once he was pope as Julius II, transferred the prize in 1511 to the small sculpture court of the Belvedere, the palazzetto or summerhouse that was linked to the Vatican Palace by Bramante's large Cortile del Belvedere. It became the Apollo of the Cortile del Belvedere and the name has remained with it, though the sculpture has long been indoors, in the Museo Pio-Clementino at the Vatican Museums, Rome.
In the 1530s it was engraved by Marcantonio Raimondi, whose printed image transmitted the famous pose throughout Europe.
...For four hundred years after it was discovered the Apollo was the most admired piece of sculpture in the world. It was Napoleon's greatest boast to have looted it from the Vatican. Now it is completely forgotten except by the guides of coach parties, who have become the only surviving transmitters of traditional culture.
