Pomponii Læti De Romanis magistratibus, sacerdotiis, iurisperitis, et legibus, ad M. Pantagathum libellus
A Latin treatise on Roman magistrates, priesthoods, jurists and laws by Giulio Pomponio Leto, printed in Paris in 1550 by Vascosan for scholars of Roman antiquity. The picture is not a text page but the marbled endpaper and bookplate of the John Carter Brown Library, showing a heraldic shield in a cartouche above its name, over swirled green, ochre and red marbling a designer could borrow for textured backgrounds.
