Dissertatio medica inauguralis de haemorrhoidibus caecis
A Latin medical dissertation by Johann Jacob Hering, printed in Leipzig in 1694 by C. Fleischer as an inaugural academic thesis on hidden haemorrhoids. Its pictures are printer's ornaments: a large decorated initial P, a foliated S with a cross-like motif, an ornamented I set beside running Latin text, and a flower-and-fruit tailpiece, all in dense black woodcut style that a designer could draw on for historical initials, borders and decorative headpieces.
