Decertatio fidei et heresis
A 1505 Paris book of theological debate on faith and heresy by Valerand de la Varanne, printed and sold by the bookseller-printer Robert de Gourmont for scholars and clergy. The one picture is a bookplate-style ex libris: a framed woodcut with a tree, a shield, two winged griffin-like beasts flanking it, and the printed name Robert Gourmont, offering a designer a model for symmetrical heraldic framing with ornamental scrollwork borders.
