Polydori Vergilii Vrbinatis de inuentoribus rerum libri tres
A Latin humanist treatise by Polydore Vergil, printed in 1503 by Tacuino and aimed at scholars, on the origins of human inventions. The single picture is a reproduction of a medieval wax seal, shown as a red almond-shaped impression with a standing crowned figure and lettering around its rim. A designer might take its dark, glossy red wax against a warm cream ground, and the framed figure inside a pointed oval as a motif for emblems or heraldic stamps.
