Abstract
A reconstruction of the medical instruction of the iatrosophists in Alexandria (5th–7th century) faces serious problems, because the sources provide us with no information on either their organisation or the biographies of their teachers. Nonetheless, some key points can be established that were characteristic of the teaching of the iatrosophists. These include the medical curriculum, the textbooks used, the type of lectures, the practical training, and the teaching units on philosophical themes. Further, it seems that Gessius initiated this type of teaching, and in the process made numerous borrowings especially from his philosophy teacher Ammonius. Ultimately, the rise in the teaching of the iatrosophists can be explained by different innovations in educational politics that can also be detected in other parts of the Roman Empire at the same time.
