The silver ring bears the seven traditional Archangels, or Planetary Angels; Michael, Gabriel, Camael, Raphael, Sachiel, Anael and Cassiel. Inside is engraved DUCITUR PER ANGELOS, ‘Guided by Angels’. The black ring holds the signatures of seven Medieval spirits or angels, variously acclaimed ‘demon’ status by past mystics; Dagon, Azervial, Adatiel, Cassiel, Camriel, Adnachiel and Anael. Inside this is engraved TENTATUS A DAEMONIBUS, ‘TEMPTED BY DEMONS’.
