The alchemical treatise The Golden Age Restored was written in Tannenberg in 1622 by an unknow German physician, initiate and alchemist under the pseudonym Henry Madathanas. 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 with the title Musaeum Hermeticum. 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.
