The Magician's Glass

This glass, into which a person looked when he wished to solve the future, or to ascertain whom he or she was to marry, was used by Welsh, as well as other magicians. The glass gave back the features of the person sought after, and reflected the future career of the seeker after the hidden future. It was required that the spectator should concentrate all his attention on the glass, and, on the principle that they who gazed long should not gaze in vain, he obtained the desired glimpse. _Cwrt Cadno_, already referred to, professed to have such a glass.

But, the magician's glass is an instrument so often mentioned in connection with necromancy in all parts of the world, that more need not be said of it.
