William Jones’s Icones is one of the most scientifically important and visually stunning works on butterflies and moths ever created. Icones contains finely delineated paintings of more than 760 species of Lepidoptera, many of which it described for the first time, marking a critical moment in the study of natural history. Yet until now, it has never been published—the only existing manuscript copy is housed in the archives of the Oxford University Museum of Natural History. With Iconotypes, Jones’s work is published for the first time, accompanied by expert commentary and contextual essays, and featuring annotated maps showing where each specimen was discovered.
