Of the many properties of Amethyst, a unique one you'll see often is that is 'prevents drunkenness' or keeps you from becoming intoxicated. This unusual property is often associated with a myth involving Bacchus, the Roman God of the grape-harvest, winemaking and wine. However, there is an earlier association between Amethyst and Wine - and goats. This story starts with the Ancient Egyptians who were trying to plant some grapes to make wine. Apparently, goats have always been notorious for running amok in Vineyards and the Egyptians often had their vineyards picked clean by hungry goats.
The Egyptians, Goats, Wine and Amethyst - a flow chart
Amethyst is the birthstone for the month of February, and is the stone for the Zodiac sign Capricorn, the sign of the goat. Goats have a reputation for destroying vineyards by trampling and eating the fruits from the vines. Even the Egyptians knew goats ruined vineyards and so it became legend that goats thwarted off drunkenness. Because Amethyst was the stone of the Goat, the ability to ward of drunkenness became a property of the crystal by association. Amethyst became a stone that helped one stay focused and helped keep a clear conscience. The crystal was also believed to protect against diseases, evil sorcery, and witchcraft.
These beliefs were carried on by other many ancient cultures such as the Greeks, Romans, Incas, and Peruvians. Amethyst became an everyday object in peoples lives. Soldiers would wear the crystals into battle. Drinking vessels and bowls were inlayed with or carved out of the crystal. Amethyst would be carried as a Talisman, and used in architectural details.
