I wore them all night long and not one angel or demon appeared to serve or threaten me. Even stuck them in a holy book and they never moved. What gives? Actually they were very nice, fit well, and the engraving was most interesting. I'll have to consult my library and find the comparable markings in some eldritch tome gathering dust in there. They do look familiar, and probably Dr. John Dee himself had similar rings. I'm sure you will enjoy them.
