The Richelieu library of the Louvre, connected to the Tuileries, was also set on fire and entirely destroyed. The rest of the Louvre was saved by the efforts of the museum curators and fire brigades. Prosper-Olivier Lissagaray, later a lover of Eleanor Marx, asserted that many of the fires were caused by artillery from the French army, and that women in the Commune were wrongly blamed for arson. The consensus of later historians is that most of the major fires were started by the National Guard and several organised Communard groups; but that few if any fires were started by the Army or by local women. In addition to public buildings, the National Guard also started fires at the homes of a number of residents associated with the regime of Napoleon III, such as that of historian and playwright Prosper Merimee, author of "Carmen".
