In "The Wealth Of Nations", Adam Smith discusses the price of corn in ancient times. Apparently, books such as "Chronicon Preciosum: or An Account of English Money, the Price of Corn and Other Commodities, for the Last 600 Years" (written in 1707) document the price of corn. This would seem to indicate that Europeans were eating corn since at least 1107.
However, I "learned" in school that it was Columbus who brought corn to Europe after 1492.
When Adam Smith discusses "corn", is he referring to some other vegetable food which differs from "corn on the cob"? Or, did the Europeans in fact have corn before the time of Columbus?
