M564 Specific manuscript identifier
The bookplate features a reproduction of a technical drawing by Leonardo da Vinci. It depicts an artist utilizing a perspective apparatus—a device consisting of a framed grid and a fixed sighting point—to accurately render a three-dimensional sphere onto a two-dimensional surface.
Faint traces of mirror-image script are visible on the right side of the page, caused by the ink from the facing page "bleeding through" or transferring over centuries of contact.
