We think this week's post counts for manuscript Monday and maybe even miniature Monday too! This is a bifolium – a sheet folded to make two leaves, or four pages of text – from a very small prayer book in Dutch. It was produced in the Low Countries sometime during the fourteenth century. The dimensions of each page are 72 x 76 mm, or about 2.8 x 3 inches.
You can find more about this bifolium in the Digital Scriptorium. It's fragment number 128 in the Fragmenta Manuscripta Collection: a group of leaves, binding waste, and other manuscript fragments assembled by John Bagford in the seventeenth century.
