Abstract

Determination is made of the chronological limits and authorship of the widely known and popular during the Middle Ages treatise "De viribus herbarum", containing extensive medicamentous references. The author of the paper proceeds from the critical analyses of opinions and commentaries made by his predecessors, compares various editions of the translations of the poem, resorts to the linguistical method and determines with greater precision a number of additional indirect evidence and documental data. A discussion is made of the influence of the poem exerted upon the school of Salerno and the "Salernian Health Code".
