Praxis Barbettiana
Praxis Barbettiana is a 1665 medical treatise by Paul Barbette, printed in Amsterdam by Jacobus Lescaille for a clinical and pharmaceutical readership. Its two pictures are printer's ornaments: a symmetrical scrolled flourish with looping curls and a small finial, and a decorated woodcut initial P with foliate filling beside lines of Latin text. A designer could take from them the balanced arrangement of seventeenth-century scrollwork and the contrast between a heavy initial and a light text block.
