Disputatio medica inauguralis de calculo vesicae ...
A Latin medical dissertation of 1674 by Johann Friedrich Gieseler, printed at Leiden by the Elzevier heirs for university-trained physicians and students. The single picture is a woodcut-style ornamental headpiece of a central grotesque mask surrounded by symmetrical scrolls, foliage and curling tendrils, which a designer could adapt as a decorative divider or border motif.
