The claim says the marble copy "remains in Paris." The official Louvre collections record contradicts that.

According to the Louvre entry for Brutus:

• it is a marble bust;
• it is a copy after the bronze original in the Capitoline Museums;
• it is "On long-term loan : Musée des Beaux-Arts, Tours";
• its current location is "Tours (France), Musée des Beaux-Arts".

That means the marble copy is not currently in Paris.

The same Louvre record also says the marble work is by François Joseph Boiston, dated 1792, and was presented to the National Assembly on 1 September 1792. So the museum’s own documentation identifies it as a specific 1792 marble copy with a documented French collection history, not simply a confiscated object that still "remains in Paris."

This sentence is contradicted by the Vatican Museums’ own catalog entries for major works returned after the Napoleonic seizures.

Examples:

• Raphael’s Transfiguration: the Vatican Museums catalog says it was transferred to Paris in 1797 under the Treaty of Tolentino, returned to Rome in 1816, and is now in "SCV ➔ Edificio della Pinacoteca ➔ Pinacoteca Vaticana ➔ Sala VIII."
• Caravaggio’s Deposizione di Cristo: the Vatican Museums catalog says it was transferred to Paris in 1797, returned to Rome in 1816, and is now in "SCV ➔ Edificio della Pinacoteca ➔ Pinacoteca Vaticana ➔ Sala XII."
• Apollo del Belvedere: the Vatican Museums catalog places it in "SCV ➔ Museo Pio Clementino ➔ Cortile Ottagono del Belvedere ➔ Gabinetto dell'Apollo."
• Laocoön: the Vatican Museums catalog places it in "SCV ➔ Museo Pio Clementino ➔ Cortile Ottagono del Belvedere ➔ Gabinetto del Laocoonte."

Those are museum galleries/courts within the Vatican Museums, not the Vatican Gardens. So describing the main returned works as located in the Vatican Gardens is inaccurate.
