Doctor John Dee had a medallion similar to this, I believe; an Archangel at each cardinal point of the compass, and was utilised when making protective magic circles. The symbols look like Dee and Kelley's Enochian writings. Doctor Dee is a sort of hero of mine - he was the last example of a Royal Magician, at the call of Queen Elizabeth I. Doctor Dee's life and works are utterly fascinating. His 'Scrying Glass' and some of his other accoutrements are kept in the British Museum.
