Was pizza invented in the United States? Many people seem to think so, given its popularity across the fifty states. America has its own forms of pizza, but pizza’s clearest origins are in Italy, in one city in particular. Like many foods however, its deepest origins lie across many cultures. After all, the idea of baking flour and adding toppings to it is pretty straightforward. Some of the early recorded evidence for this comes from 6th century BCE Persian soldiers in the army of Darius the Great who mixed cheese and dates on baked flat bread. There are traces of Stone Age residents in the Italian peninsula baking bread beneath a fire, and then using it as a plate - something also common in ancient Greece. Certainly the close proximity and cross-conquests of people in the larger Mediterranean region meant that there was ample opportunity for the sharing of food ideas. The word “pizza” is said to have come from the word “pita” which describes a flat bread in many cultures around the Mediterranean.

Every since human beings have been gazing up at the stars, we have wondered whether there are other living creatures out there. Ancient humans often believed that the gods resided above us, and the stars and constellations they formed became part of a living, divine cosmos of which earth was an integral part. Specific beliefs varied from culture to culture. The Mongolians had one of the simplest names - they called it the “Great Blue Sky.” When Genghis Khan needed to win a battle, or the lowliest nomad had to find his herd, it was to the “Great Blue Sky” over the Mongolian countryside that they turned to for help.

The answer lies buried in decisions made more than a hundred years ago, when the typewriter first appeared on the plains of industry.
