Supplement A and Supplement B
Between 1841 and 1844, Count Guglielmo Libri, who had sought refuge in France and become a naturalized French citizen, conducted official inspections of various French libraries, due to the aftermath of Napoleon’s transfer of works of art. Accused of stealing manuscripts, he fled to England with a substantial haul, including parts of the notebooks A, B, and E from the Institut de France. Some of this material was lost.
Using the last 34 pages of Notebook A, obtained by cutting 17 bifolios in half, Libri created a volume where each page was placed inside a paper bracket and then sewn into the binding. The title page reads “Notes & Dessins de Leonard de Vinci,” featuring his signature and the date 1875. To conceal their origins, he erased Leonardo’s original numbering. He treated the remains of Notebook B similarly.
Both volumes were sold and became part of Lord Ashburnham’s library, cataloged as 1875/2 for A and 1875/1 for B. After lengthy negotiations, the volumes were returned to France and placed in the National Library with the shelfmarks Italien 2038 (A) and 2037 (B). They were eventually returned to the Institut de France, receiving the shelfmarks 2185 and 2184.
Manuscript C
(cc. 11 + 30, mm. 310 x 222) Manuscript C is in folio format and bound in leather, containing sixteen bifolios folded into thirty-two pages. The cover plates are decorated in gold, with ornamental designs at the corners and inscriptions at the center of the first plate.
