Dissertatio medica publica de vena portae, ...
A Latin medical dissertation by Johannes Guilielmus Ayrer, printed at Altdorf in 1687 with Schönnerstædt type and held by the Wellcome Library. Its two pictures are small black woodcut ornaments, symmetrical floral and fruit scrollwork set as headpieces, showing how early modern printers framed text with dense, balanced decoration a designer could adapt for borders or dividers.
