Tractatvs de potestate svmmi pontificis in rebvs temporalibvs : adversus Gulielmvm Barclaivm
A 1610 Latin treatise by the Jesuit cardinal Robert Bellarmine, printed in Cologne at the expense of Bernhard Gualtherus, defending papal authority in temporal affairs against William Barclay. The pictures are small woodcut and engraved ornaments: a diamond-shaped scrolled panel, a framed square motif, a decorated initial letter, and a cardinal's coat of arms with a galero and tassels, which a designer could draw on for dense, classical, scholarly page furniture.
