George Ripley was a 15th-century English alchemist and a canon of the Augustinian priory at Bridlington in Yorkshire. He is said to have studied in Italy and elsewhere in his youth.
He dedicated to King Edward IV The Compound of Alchemy, a poem explaining the secrets of alchemy through the metaphor of twelve gates, and won fame as England’s foremost alchemist. Because of that fame, an alchemical picture scroll made after his death also came to be called the Ripley Scroll.
