First Latin Egenolff edition of a Medieval collection of medicinal recipes intended, as the title "Treasury for the Poor" suggests, to provide readily available and inexpensive remedies to common ailments, probably for medical practitioners of modest means, students and (when they were at least able to read Latin) common people who might need to take care of their own ailments. One of the most important sources for Medieval pharmacology, it makes much use of animal parts and common plants and gives a very intimate picture of medical practices among the common people from medieval times until far into the Renaissance. Many recipes are said to derive from Hippocrates, Galen and Avicenna, and an appendix presents the Hippocratic oath. It is widely believed that the oath was written by Hippocrates, himself, or by one of his students, to establish certain ethical standards. It was first printed in Salamanca ca. 1485, when it was attached to Juan de Pastranas Compendium grammaticae, so that it was sometimes incorrectly attributed to him. From at least ca. 1492, it was attributed to "Piero Spano" or "Petrus Hispanicus" (Peter of Spain), which received various interpretations but is now generally believed to refer to the Portuguese Peter Juliani (ca. 1215-1277), better known from his 1276 election as Pope John XXI, as the present edition suggests. It went through dozens of editions in numerous languages before 1600, but declined in popularity in the course of the 17th century. Beginning with a German edition of 1537, Christian Egenolff and his heirs were the leading publishers.
