Abstract. Alchemists—driven by greed and curiosity—did not manage to produce gold from cheap materials, but they certainly initiated and advanced chemical knowledge. The discovery of aqua regia by the Arab alchemist Jabir Ibn Hayyan in the sixth century introduced a chemical technology for the extraction of gold from its ores.
