Theses medicae de mensium suppressione,
A Latin medical dissertation on suppressed menstruation, defended under Johann Rudolph Saltzmann as presiding professor and printed at Strasbourg in 1633 by the heirs of Paul Ledertz for academic readers. The single picture is a large decorative woodcut initial D, its letter body filled with interlaced foliage, scrolls and leafy tendrils framed by a dense border of stylised vines, a useful model for historic ornamental capitals and pen-flourish borders.
