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.

Summary The genealogy of observation as a philosophical term goes back to the ancient Greek astronomical and medical traditions, and the revival of the concept in the Renaissance also happened in the astronomical and medical context. This essay focuses primarily on the medical genealogy of the concept of observation. In ancient Greek culture, an elaboration of the concept of observation (tērēsis) first emerged in the Hellenistic age with the medical sect of the Empirics, to be further developed by the ancient (...) Sceptics. Basically unknown in the Middle Ages, the Empirics’ conceptualisation of tērēsis trickled back into Western medicine in the fourteenth century, but its meaning seems to have been fully recovered by European scholars only in the 1560s, concomitantly with the first Latin translation of the works of Sextus Empiricus. As a category originally associated with medical Scepticism, observatio was a new entry in early modern philosophy. Although the term gained wide currency in general scholarly usage in the seventeenth century, its assimilation into standard philosophical language was very slow. In fact, observatio does not even appear as an entry in the philosophical dictionaries until the eighteenth century—with one significant exception, the medical lexica, which featured the lemma, reporting its ancient Empiric definition, as early as 1564.

“Sacra à Deo in corde discenda, natura ex natura.” Johann Christian Senckenberg's Observationes as a Medico-Theological Writing Method. In his early diaries, the pietist physician Johann Christian Senckenberg has taken down large amounts of observation data which mostly concentrated on his own body and soul. Earlier research has mistaken his diligent self-observation for hypochondria and unworldliness, especially since the author had never endeavoured to analyze and publish his work. The article shows that both his writing practice and his reluctance to (...) process and share its results are due to his deeply religious and firmly anti-rationalist conviction. The main purpose of his journal keeping was the attainment of religious self-knowledge and professional self-perfection. Scientific publications he considered to be hypothetical and dogmatic, be it in theology or medicine; moreover, their authors were often enough driven by their self-love and desire for fame. In his eyes, the only godly way of knowledge acquisition was the humble, diligent and minute study of divine creation according to the Hippocratic method. The most immediate and reliable way of achieving true wisdom, however, was the observation of God's work within one's own body and mind, which were subject to the effects of God's grace and punishment as well as to atmospheric, environmental and dietetic circumstances.
