“In the 1st century AD, Pliny the Elder describes use of crystal balls by soothsayers (“crystallum orbis”, later written in Medieval Latin by scribes as orbuculum). By the 5th century AD, scrying was widespread within the Roman Empire and was condemned by the early medieval Christian Church as heretical.Dr. John Dee was a noted British mathematician, astronomer, astrologer, geographer, and consultant to Queen Elizabeth I. He devoted much of his life to alchemy, divination, and Hermetic philosophy, of which the use of crystal balls was often included.”Pasted from <https://en.wikipedia.org/wiki/Crystal_ball>
