Opera quae extant omnia
A 1645 Latin medical compendium by Adriaan van den Spiegel, printed in Amsterdam by Johannes Blaeu for physicians and students of anatomy. Its pictures range from symmetrical scrollwork ornament panels to fine line-engraved anatomical plates of the arm and hand with lettered reference points, offering a designer ornamental flourishes for decorative borders and a clean diagrammatic style for technical drawings.
