[A look at the Hippocratic treatise On Hemorrhoids in the Byzantine Era]

In two manuscripts of Galen's De compositione medicamentorum secundum locos, the Marcianus gr. V 7 and the Vaticanus Reginensis gr. 172, Galen's text is interrupted by a brief anthology about aetiology and therapy of prolapses, haemorrhoids and anal inflammations. Both manuscripts present a chapter, titled (see text), which consists of chapters 1-2 (p. 146, 2-12 July) of the Hippocratic On Haemorrhoids. My contribution presents this new document about the knowledge of this Hippocratic work, neglected by modern scholars, but well known by Byzantine medical writers.
