Arte de cãto llano y cõtrapunto y canto de organo cõ proportiones y modos breuemte cõpuesta & nueuamte añadida y glosado por Gõçalo Martinez de Bizcargui
A 1538 Spanish treatise on plainchant, counterpoint and organ song by Gonçalo Martínez de Bizcargui, printed in Zaragoza for students of church music. Its pictures are woodcut diagrams of the musical staff with clef and solmization syllables, a diagram of octave and interval ratios, and a decorated initial and a printer's mark with lions and a bordered roundel. A designer might take the staff-and-note diagrams as clean linear notation models and the ornate initial and lion roundel as dense, hand-cut border and emblem work.
