De l'avthorite royale.
A 1615 French treatise on royal authority, attributed to Étienne Pasquier and printed in France, aimed at readers interested in monarchy and political argument. The single picture is a bookplate-style ornament: an oval frame of interlaced knotwork and scrolls enclosing the Latin word LIBRO and LIBER, with the initials G and H below, which a designer could borrow for an ex libris or label.
