Thomae Willis ... Opera omnia, nitidius quàm vnquam hactenus edita, plurimùm emendata, indice rerum copiosissimo, ac distinctione characterum exornata
Thomas Willis's collected works, a Latin medical and anatomical compendium published in Cologne in 1694 and edited by Gerardus Blasius for physicians and students. The pictures are black-and-white engraved and woodcut plates: two diagrams of a branching structure resembling a tree or leaf, labelled with letters and figure numbers, plus decorative woodcut initial letters with interlaced foliage and scrollwork that a designer could borrow for ornamental capitals and vintage frames.
