In divination, an anachitis, or anancitis,[1] meaning "stone of necessity"[2] is a stone used to call up spirits from water.[3] It was described as a type of diamond by Martin Ruland the Elder.[1]
The stone was used in classical antiquity by the Magi, being described by Pliny the Elder as one of their "dreadful lies".[4] Its use had fallen out of favour by the Middle Ages.[5]
