A 1527 Paris printed astronomy textbook by Johannes de Sacrobosco, issued by Simon de Colines for students of the University of Paris, with commentary by Jacques Lefèvre d'Étaples. Its two framed woodcut plates show a diagram of the spheres of the universe with a central earth and zodiac ring, and an armillary sphere attended by figures labelled Urania and Ptolemaeus. A designer might draw on their dense ring diagrams, decorative strapwork borders, and the compact ornamental lettering of early Renaissance title pages.
