Amethystos Callinectes. A species of swimming crabs now believed to be extinct.
The Greek word "amethystos" may be translated as "not drunken": a = “not" and
methustos = "intoxicated". And Callinectes: Calli = "beautiful", nectes = "swimmer".
A reference to the belief that the stone was an antidote against drunkenness. The
ancient Greeks wore amethyst jewelry and carved drinking vessels from it in the belief
that it would prevent intoxication. These mythical crabs would allegedly grow Amethyst crystals on their bodies and were prized during the height of the Ancient Greek civilization. Their shells, claws and legs were harvested in vast numbers and used extensively for the Greek Aristocrats symposia; A convivial meeting for drinking, music, and intellectual discussion. These mythical creatures are now believed to be extinct but there have been a few unconfirmed sightings in the Aegean and Mediterranean Seas, specifically around the sunken city of Pavlopetri.
