Dactylomancy

Dactylomancy is a form of divination practised with rings in ancient times. There are various methods used.

One method involved placing gold or silver rings on the fingernails in certain conjunctions of the planets.

In another way a round table is inscribed with the letters of the alphabet and a ring suspended above. The ring will then spell out the message.

Another method involves suspending a ring within a glass. If the glass is struck once it will indicate yes, and twice will be no
