Vol. 1: First published edition of two 13th century Anglo-Norman medical treatises translated from Latin. Matthaeus Platearius and his brother Johannes were the sons of a female physician from the Salerno school who was married to Johannes Platearius I; it is possible that she was Trotula. The second volume includes all vernacular medical texts contained in Trinity College, Cambridge, MS 0.1.20, presenting a treatise on visiting the sick and a verse translation of the first part of the celebrated gynaecological compilation known as `Trotula', with their Latin originals. To these are added  the Euperiston and the Trinity `Practica'. Hunt's Introduction illustrated characteristic features of the medieval medical compendium through the example of the Speculum medicorum, which was previously unstudied.
