Featured on PDR in the collection Martin Frobenius Ledermüller’s Microscopic Delights (1759–63)

Novel and astonishing as they may have been for Enlightenment readers, it is difficult for us to comprehend how the magnifications of lice, fleas, houseflies, and other vermin might have been conceived as amusements for the mind and eyes. In full hand-colored clarity, stingers, pincers, biting mouthparts, and other irksome insect organs become menacing monsters thanks to the powers of the microscope in Martin Frobenius Ledermüller’s three-volume Mikroskopische Gemüths- und Augen-Ergötzung (Microscopic Delights of the Mind and Eyes).
