Abstract
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 . 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
