This particular Pete Green is an Historic Trader who lives and works in a small mediaeval market town in the heart of Norfolk, U.K.
He is also a Mediaeval Bookbinder, and specialises in trading in rare Incense Resins. As well as this he is a professional astrologer, and is probably one of the few mediaeval apothecaries whom you are likely to meet.
