A photograph of a thick, closed manuscript volume viewed from the edge. The pages are light tan with irregular, hand-cut edges typical of historical paper or parchment. The cover is made of a pale, thick material, likely vellum or parchment, which appears slightly worn and warped at the edges. Below the image of the book is a black rectangular area containing modern white text providing copyright and institutional provenance.
