Observationes circa viventia, quae in rebus non viventibus reperiuntur cum micrographia curiosa : sive rerum minutissimarum observationibus, quae ope microscopii recognitae ad vivum experimuntur ...
Filippo Buonanni's 1691 Latin treatise on microscopic observations, printed in Rome by Domenico Antonio Ercole, presents early microscopy of tiny organisms found in non-living matter for a scholarly audience. Its plates are engraved, with numbered specimens of insects, larvae, pupae, and fine hairs and scales drawn in dense hatched line. A designer could take the careful numbered-plate layout and the fine cross-hatching that renders fur, feathers, and segmented bodies.
