In alchemy, the term chrysopoeia (Ancient Greek: χρυσοποιία, khrusopoiia) means transmutation into gold (from the Greek χρυσός, khrusos, "gold", and ποιεῖν, 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 an alchemical papyrus, the Chrysopoeia of Cleopatra, which was written in the first centuries of the Christian era. The papyrus features the idea of "one the all" (ἕν τὸ πᾶν, hen to pān), a concept that is related to ouroboros and to hermetic wisdom. Stephen of Alexandria wrote a De Chrysopoeia. Chrysopoeia is also a 1515 poem by Giovanni Augurello.
