Antoine-Chrysostome Quatremère de Quincy (21 October 1755 – 28 December 1849) was a French armchair archaeologist and architectural theorist, a Freemason, and an effective arts administrator and influential writer on art.
Born in Paris, he trained for the law, then followed courses in art and history at the Collège Louis-le-Grand and apprenticed for a time in the atelier of Guillaume Coustou the Younger and Pierre Julien, getting some practical experience in the art of sculpture. A trip to Naples in the company of Jacques-Louis David sparked his interest in Greek and Roman architecture.
He was involved in the troubles of the French Revolution. He was a royalist in the Legislative Assembly of 1791-2, and his politics were monarchist and Catholic. As a member of the Revolutionary Committee of Public Instruction his set of three Considerations on the arts of design in France was offered before the Assemblée Nationale at a time (1791) when the continuation of the former academies was under question; he offered a program for their reform. in part by opening up the Paris salons. In 1791-92 he orchestrated the conversion of the Church of Ste-Geneviève in Paris (under the direction of Jean-Baptiste Rondelet) into the Panthéon, infilling the windows to give it the character of a mausoleum. In 1795 he was accused of taking part in the preparations for the royalist insurrection of 13 vendémiaire and condemned to death, but acquitted in time.
In July 1796, Quatremere wrote a pseudo-epistolary treatise against the French plans to seize works of art from Rome, arguing that European powers should instead contribute a sum to the papacy for protecting art and knowledge. Shortly afterward, he was behind a petition signed by forty-seven Parisian artists including Jacques-Louis David which questioned the benefits of displacing art from Rome; although prudently worded, there was a vituperative official response.
