The aim of project D-2-3 was to investigate Stoic and Pneumatist conceptions of mental processes and illnesses and of the psychology of mental events (place, bodily factors involved, exact mechanisms), and to assess their relation to relevant philosophical and medical contexts. The study focused on the Pneumatist physician Athenaeus of Attalia (1st c. BC), whose works have only survived in fragments. Athenaeus was frequently quoted, especially for his doctrine of elementary physics, his theory of reproduction and his conceptual distinction between various types of causes. A collection of fragments with translation and commentary was a longstanding desideratum fulfilled by this project.
The aim of Project D-2-2 was to reconstruct the medical doctrines of the influential Pneumatist physician Archigenes of Apamea (early 2nd c. AD) by preparing a collection of the fragments with translation and commentary, thus laying the foundations for a detailed analysis of the interaction between the Stoics and the Pneumatists. Archigenes was famous particularly for his elaborate classification of various kinds of pain as diagnostic indicators of diseased places within the body; he was also quoted by later authors for his pulse theory.
