Greek and Roman patients under Galen's gaze: a doctor at the crossroads of two cultures.

Born in Pergamum in 129 A.D., Galen received his first medical training in his native city and then continued his studies in Smyrna, Corinth, and Alexandria.

[At the origin of the theriac: the receipt of Andromachus].

The Greek physician Galen of Pergamum (129-c. 210) has preserved in his two tracts De antidotis and De theriaca ad Pisonem the original recipe of the theriac under the name of Andromachus. Galen specifies that Andromachus was the first to add flesh of vipers in this pharmacological preparation.

Art, science and conjecture, from Hippocrates to Plato and Aristotle.

This paper attempts to study the notion of stochazesthai in the Hippocratic Corpus in relation to Hippocratic reflections on the status of the medical art. Considering the passages where the verb stochazesthai is employed, we can see that this word is not yet synonymous with the term "conjecture". The main point of interest are the relations between the Hippocratic writings and the relevant works of Plato and Aristotle.
