In alchemy, the term chrysopoeia (Ancient Greek: ?, khrusopoiia) means transmutation into gold (from the Greek , khrusos, "gold", and , poiein, "to make"). It symbolically indicates the creation of the philosopher's stone and the completion of the Great Work.
The word was used in the title of a brief alchemical work, the Chrysopoeia of Cleopatra attributed to Cleopatra the Alchemist, which was probably written in the first centuries of the Christian era, but which is first found on a single leaf in a tenth-to-eleventh century manuscript in the Biblioteca Marciana, Venice, MS Marciana gr. Z. 299. The document features an ouroboros containing the words "the all is one" ( , hen to p?n), a concept that is related to Hermeticism. Stephen of Alexandria wrote a De Chrysopoeia.Chrysopoeia is also the title of a 1515 poem by Giovanni Augurello.
