Enchiridion musices Nicolai Wollici Barroducensis de gregoriana et figurativa atque contrapuncto simplici percommode tractans, omnibus cantu oblectantibus, perutile et necessarium.
This 1512 Paris music treatise by Nicole Volcyr de Sérouville, printed by Jean Petit for singers and students of plainchant, counterpoint and figured music. The four pages show dense black square-note plainchant staves on red-ruled lines, with Latin text and Evouae endings set between the notation, and a designer might take their rhythmic grid, stacked staff bands and tight typographic texture as a model for structured layout.
