Ancient Romans believed that if one drank their wine with amethyst goblets, they would not become inebriated. The story of amethyst comes from Greek legends. "The god of wine, Bacchus, was insulted one day by a mere moral. He swore the next mortal that crossed his path, would be attacked by his fierce tigers. Along came a beautiful maiden named Amethyst. Goddess Diana turned Amethyst in a beautiful statue of quartz to save her from the tigers claws. Remorseful Bacchus swept tears of wine over the stone maiden, creating a lively purple stone."
