BARLEY
Barley is one of the oldest domesticated grain crops. It has been cultivated for over 8000 years. In Athens barley was, according to Pliny, the special food of the gladiators (the hordearii, or 'barley-eaters').
Barley is grown by the Aymara people on the highest cultivated plot of land in the world at 15,420 feet near Lake Titicaca. The lake is the border between Peru and Bolivia at 12,500 feet, and the area was home to one of the oldest civilizations in the Americas. The Aymara people that live there still practice ancient methods of agriculture. Potatoes and quinoa are also grown there at slightly lower elevations.
In about 1305, Edward I of England decreed that one inch should be the measure of three barleycorns, and English shoe sizing began; thus a child's shoe that measured 13 barleycorns became a size 13.
Historians report that up until the 16th century, it was the most important grain on the European continent. It was also used as currency and as a measuring standard.
Almost half the United States crop of barley is used for brewing beer and most of the rest is used for feeding livestock.
