Aqvatilium animalivm historiæ, liber primvs : cum eorvmdem formis, ære excvsis
Ippolito Salviani's 1554 Roman treatise on aquatic animals, printed in Latin for naturalists and scholars, is a early zoological survey with engraved fish plates. Its pictures show single fish set vertically on bare pages, rendered in fine hatched engraving with plain shading, a clear model for designers wanting precise line-based specimen studies.
