The Ripley Scroll of the Royal College of Physicians of Edinburgh
Abstract:
Alchemical scrolls associated with George Ripley are unusual documents which illustrate the pursuit of the Philosophers Stone. Scrolls vary from about 5 feet in length by 5 inches wide to over 20 feet long and about 3 feet wide. There are 16 scrolls in libraries in the UK and 4 in the USA. Ripley whose name is attached to the scrolls was a Canon of Bridlington in Yorkshire and lived from about 1415 to 1495. He is renowned as an alchemist and author of alchemical works in rhyme, and his verses are used on the scrolls. Some of the scrolls were produced in the 16th century, in Lübeck, probably at the request of John Dee the Elizabethan polymath. A Ripley scroll is in the library of the Royal College of Physicians of Edinburgh to which it was presented in 1707. The only published description of this scroll appeared in 1876, and it has not apparently been studied since. Interest in Ripley scrolls has grown in recent years and there have been a number of publications describing them since 1990. The Edinburgh scroll is described and is compared with the other scrolls which have been seen personally or for which detailed descriptions have been published. The origin, significance and use of Ripley Scrolls are discussed in an attempt to define their contemporary role.
