So begins the last part of 10a 215. The Wyse Boke of Maystyr Peers of Salerne is a 14th-century English medical text, and includes sections on the four humors, signs of deaths, herbs, and recipes. According to a 1993 article by Carol F. Heffernan, the book is attributed to a Peter de Barulo, who lived England in and around 1387. By all accounts, it seems to have been a popular and well-known book, so it’s not surprising that a copy of it ended up in 10a 215.
