Superstitions and Their Sources: Thomas

A most interesting medieval treatise on the virtues of precious stones forms part of the De rerum natura of Thomas de Cantimpre (1201-1270), who was a pupil of Albertus Magnus and composed his work between 1230 and 1244. The Latin text has never been printed, but the book was translated into German by Konrad von Megenberg about 1350. Strange to say, the translator did not know the name of the writer and supposed when he began to translate the book that it was by Albertus Magnus. In many cases Thomas de Cantimpre merely copies the statements of older authors, but occasionally he gives us new material, or at least a new version of his originals.

The renowned medieval philosopher and theologian, Albertus Magnus (1193-1280), for a short time Bishop of Ratisbon, and who later taught theology in the University of Paris and had the great St. Thomas Aquinas for a pupil, was not altogether free from the superstitions notions of his time, traces of whch appear in certain of his numerous writings. Many years after his death some of this material was extracted from his works and, amplified by additions from other sources, was published under the title "Secrets des vertus des Herbes, Pierres et Bestes." Of this there are two versions, one being an epitome of the other and termed respectively "Le Grand Albert" and "Le Petit Albert." These little books were often reprinted and widely circulated, and eventually enjoyed great popularity among the French peasants. Indeed, even to the present day they may still be met with in out-of-the-way parts of rural France.
