Petrus Comestor; Alexander de Villa Dei; Petrus Pictaviensis
This is a 1350 manuscript compendium of scholarly texts by Petrus Comestor, Alexander de Villa Dei and Petrus Pictaviensis, held by a Swiss library and likely made for clerical or university readers. The pages are dense with hand-lettered columns of Latin text set beside colored diagrams: branching family trees with roundels, arched frames, and a winged cherub figure with rubrics, all in red, blue and gold ink. A designer might take the tree and roundel structures as a model for organizing hierarchical information.
