The anonymous alchemical treatise A Tract of Great Price concerning the Philosophical Stone was published by an unknow German sage and initiate in the year 1423, under the title The True Teaching of Philosophy concerning the Generation of Metals and their True Origin. It was included in 1893 by Arthur Edward Waite – a British poet, writer, Freemason, esotericist and one of the greatest scholars of the Western Mystery Tradition – in the first volume of the English edition of The Hermetic Museum, a collection of the most celebrated ancient alchemical texts, originally published in 1678 in Latin. It is undoubtedly one of the most interesting alchemical texts that have come down to us from the mists of an archaic past of wisdom and knowledge of the elements of nature and their transmutation.
