Book excerpt: This study reexamines the invention of the emblem book and discusses the novel textual and pictorial means that applied to the task of transmitting knowledge. It offers a fresh analysis of Alciato’s Emblematum liber, focusing on his poetics of the emblem, and on how he actually construed emblems. It demonstrates that the “father of emblematics” had vernacular forebears, most importantly Johann von Schwarzenberg who composed two illustrated emblem books between 1510 and 1520. The study sheds light on the early development of the Latin emblem book 1531–1610, with special emphasis on the invention of the emblematic commentary, on natural history, and on advanced methods of conveying emblematic knowledge, from Junius to Vaenius.
