Guiliel Amesii Medulla theologica
A 1656 Latin theology treatise by William Ames, printed in Amsterdam by Johannes Janssonius and held by Princeton University Library. Its pictures are decorative printers' ornaments: a symmetrical flourish with scrolls and a pendant, a large initial A, and a historiated-style initial T framed by foliage and scrollwork, all in woodcut-like black on cream paper. A designer could draw on these for ornamental initials, symmetrical flourishes, and printed-page vignettes with a seventeenth-century feel.
