Dissertatio inauguralis de propriorum oculorum defectibus ad leges mechanices revocatis ...
A Latin medical dissertation by Johannes Ott, printed in Basel in 1671 by Jacob Werenfels, written as an academic thesis on defects of the eye for university-trained readers. The single picture is a woodcut of a flowering bouquet set in a footed urn, with tulips, a fritillary, and a carnation rendered in dense black-and-white line work that shows how engraved botanical ornament can be built from hatching and contour.
