Disputationes de recta ratione purgandi, docentes quos, quibus pharmacis, et quo tempore, purgare deceat ...
A Latin medical dissertation by Melchior Sebisch, printed in Strasbourg in 1621 by Johann Repp, on the proper use of purgatives and laxatives in medicine. Its pictures are decorative woodcut initial letters, an ornate A and S repeated, with interlaced scrollwork, hatched shading and foliate fills that a designer could borrow for drop caps, monogram frames or early-modern typographic ornament.
