When the Europeans arrived, corn could be found virtually everywhere in the American Continent. This is why the American natives were called "the corn towns", and their cultures were called "corn cultures", as compared to the "wheat cultures" that flourished in the Mediterranean, and to the "rice cultures" that prospered in the vast Asian regions.
Although the diet of the ancient Mexican people included a variety of food, it is worth mentioning that they created a corn god, whose name in náhuatl (ancient Mexican language) was "Centéotl".
Centéotl was a unique god. He didn't control any of the elements, neither did he stand among the greatest gods. He was simply the corn, the highest yielding cereal that endured plagues and freezing temperatures and that could grow under the most adverse conditions.
Centéotl was a god of the most extraordinary creation of mankind, since corn appeared on Earth six or seven thousand years before our era..
