INTRODUCTION

Galen’s De temperamentis (On Krasias, Temperaments, Mixtures) is unquestionably among his most important and influential works, providing as it does an account of one of the foundational concepts in his theory of medical practice.

Certainly, since the force of these is covered in the work on hygiene, in which the differences of the constitution of our body...”3
