Image, text and Observatio: the Codex Kentmanus.

This paper examines the inter-relationship between image, text and object in the Codex Kentmanus, which is one of the earliest records of the plants in the botanical garden at Padua, studied by Johannes Kentmann (1518-77). The manuscript shows that "observation" for Kentmann involved a gradual process of assimilating knowledge from other physicians, apothecaries, and books in order to make the plants which were originally encountered at a specific time and place into a more generalised object of study for learned physicians.
