According to Roman legend, Bacchus, the god of wine, had been insulted by a mortal, and vowed that he would unleash his sacred tigers on the next mortal he passed. That mortal was a maiden named Amethysta. In order to protect her from Bacchus’ tigers, the goddess Diana turned her into a quartz statue. Upon seeing this, Bacchus was so remorseful that he wept tears of wine over the maiden. The grapes from the wine turned the statue of Amethysta purple. And thus was amethyst born.
