A Latin treatise on optics, telescopes and optical instruments by Johann Zahn, published at Würzburg in 1685 with copperplates by Bartholomäus Kilian, addressed to scholars, astronomers and lens-makers. The engravings combine lettered ray diagrams and telescope cross-sections with lens-grinding lathes, quadrants and graduated arcs, plus plates that frame landscape and camera-obscura vignettes in scrollwork cartouches.
