Joannis Schefferi Argentoratensis De militia navali veterum libri quatuor: ad historiam Graecam Latinamque utiles
Johannes Scheffer's 1654 Latin treatise on ancient naval warfare, printed at Frankfurt for scholars of Greek and Latin history, is a scholarly reference rather than a picture book. Its woodcut ships are small and schematic, with oars, rams, sails and decks drawn in flat outline, some set inside coin-like roundels bearing inscriptions, which suggests simple diagrammatic ship forms for a designer to adapt.
