Observationes durch dessen verfertigte Microscopia deren unterschiedlichen Insecten, nebst andern unsichtbaren Kleinigkeiten der Natur, welche er nach dem Leben accurat abzeichnen und auf Verlangen hoher Liebhaber in Kupffer stechen lassen
This is a 1734 German book of microscopic studies of insects and other tiny natural things, drawn from life and engraved in copper by Cosmus Conrad Cuno and published by Johann Georg Mertz for curious patrons. Its plates show magnified insect anatomy as plain engraved line drawings with stippled and hatched shading, labelled with letters and numbers for close reading. A designer could take its precise diagrammatic linework, clean plate layouts, and the grey tonal modelling of sculpted forms.
