A 1674 Latin anatomy compilation printed in Amsterdam, gathering William Harvey's observations on animal generation with later embryology notes by Justus Schrader and others for physicians and naturalists. The pictures are copperplate engravings of hen's eggs opened at successive days of incubation, showing the developing embryo and its blood vessels spreading across the yolk. A designer might draw on their fine parallel hatching and radiating vein patterns for organic, diagrammatic linework.
