Baldi Angeli Abbatii ... De admirabili viperae natura, & de mirificis ejusdem facultatibus liber
A 1603 Latin treatise on vipers, printed in Nuremberg by Sebastian Heusler and written by the 16th-century abbot Baldus Angelus Abbatius, aimed at naturalists and physicians. Its pictures are decorative woodcut initials, ornamented letters with dense hatched shading, scrolls, and leafy filigree, which a designer could draw on for letterforms and border patterns.
