Isidorus Hispalensis · Register of Books of the Monastery of Fulda · Recipes · Blessings · Astronomic Tables · Jerome
A ninth-century manuscript compilation of Isidore of Seville's writings, a register of Fulda monastery books, recipes, blessings, astronomical tables and Jerome, made in a Carolingian scriptorium for monastic readers and now held by a Swiss library. The pictures are hand-drawn diagrams in brown ink and red and green lines: concentric circles, wheels divided into sectors, and crossing bands of lines with Latin labels, which a designer could take as a source of radial geometry, diagram layouts and early medieval calligraphic marginalia.
