Desiderii Heraldi aduersariorum libri duo. : Quibus adiunctus est animaduersionum eiusdem in librum Iamblichi de vita Pythagoræ nuper primùm editum liber vnus
A scholarly Latin commentary by Didier Hérauld, printed in Paris in 1599 by Jérémie Périer for classical scholars, correcting Iamblichus's life of Pythagoras. The single picture is a printer's ornament: a symmetrical black fleuron of scrolling acanthus-like foliage with a central pointed leaf and a small knot at the base, set into the page as a decorative break. A designer might take from it the compact, mirrored scroll structure that works well as a divider or header motif.
