De duobus amantibus
A Latin incunable printed in Paris by Antoine Caillaut, a text by Pope Pius II (Aeneas Silvius Piccolomini) in the belles-lettres tradition. The page shows a large woodcut border framed by a fleur-de-lis crown, with two upright figures flanking a central shield and interlaced vines, and the lettering around it is printed upside down in places. A designer might take the symmetrical framing, the dense black-and-white ornament and the mirrored text blocks as a model for early print borders.
