Simon Nunn

was an Egyptian born Greek alchemist who believed that all substances are composed of the four elements of nature - Fire, Water, Air and Earth. He collected together all the knowledge on khemia, as it was then known, and compiled a 28 volume encylopedia. It is thanks to Zosimus that we know what we do about Egyptian/Greek alchemy. Much of the knowledge was destroyed by the Roman emperor Diocletian and Christians who burned the library in Alexandria in 391. 021 1644 075
