Leaf from a French Psalterium written on a very thin piece of vellum. The fascinating method of production is evident with small holes pricked in the margin to ensure the perfect alignment of all lines of text. The text is written in a Gothic book hand in black ink with red rubics and several large initials decorated in delicate pen work in red and blue. One of these initials on the recto includes a human face. The text is for the most part from the book of Exodus.
