One of the most famous pieces taken under this program was the Horses of Saint Mark. The four antique bronze horses, which had adorned the basilica of San Marco in Venice after the sack of Constantinople in 1204, were brought to Paris to reside atop Napoleon's Arc du Carrousel in Paris in 1797. Several churches and palaces, including Saint Mark's Basilica, were looted by the French, which outraged the Italians and their artistic and cultural sensibilities. In 1797, the Treaty of Tolentino was signed by Napoleon, and two statues, the Nile and Tiber, were taken to Paris. These statues had previously been in the Vatican, and both were housed in the Louvre until 1815. After the defeat of Napoleon, the Nile was returned to Italy. However, the Tiber remained in the Louvre Museum and can be seen in the collections today.
