Considering that there are more than 40,000 cultivated varieties, it’s no surprise that rice has fed people so successfully for so long. Many believe the wonder crop was first cultivated in China as early as 2500 B.C. before spreading to Tibet, India and beyond. It was in India that one of Alexander the Great’s military campaigns came across rice in the 4th century B.C. In his work Geographica (“Geography”), Greek geographer Strabo (c. 62 B.C.-24 A.D.) quotes a source from the campaign: “The rice, according to Aristobolus, stands in water in an enclosure. It is sowed in beds. The plant is four cubits in height, with many ears, and yields a large produce.”
