Many people in the 1700s had private libraries in their homes. For instance, the French socialite, Madame Récamier maintained her own library, as did the Princesse de Lamballe, who was fluent in several languages. Among the books that the Princesse de Lamballe read were those written by popular writers, such as Dante Alighieri and Nicolo Macchivell. However, she read a lot of other authors even when her situation was not necessarily pleasing. This fact was stated by Madame de Tourzel, who was imprisoned at her with at La Force:
“We tried … to make our situation less painful during this period by portioning out our time in different occupations, such as the care of our room, needlework, and reading.”
The Princess’ favorite thing to read was Italian poetry, and some of these kinds of books that Princesse de Lamballe read could be found in her private library. In March 2015 many books from the Princesse de Lamballe’s library were auctioned off through Olivier Coutau-Bégarie. Here is that list:
