Important Innovations and Inventions, Past and Present. An Introduction to Sumerian Art and Culture. The Beginning Researchers agreed that BC is the year when the wheel was invented, which is more of a ballpark than an exact year. The place is Mesopotamia, the area now occupied by war-ravaged Iraq. The first wheel for transportation purposes is approximated to BC, its purpose being to move the Mesopotamian chariots.
To be completely historic, as noted here , the very beginning of the wheel goes back to the Paleolithic era 15, to , years ago. Back then, humans used logs to move large loads around. Archaeology is not the proper science for pinpointing the location of viral inventions.
There are, however, linguistic reasons to suspect the Yamnayan man buried with his wagon may have lived close to where the invention occurred. When the Spanish brought the tobacco plant back from the Caribbean, for example, they kept the local Taino word tabako. Kay was a farmer and a herder. He had dogs, horses, and sheep, and perhaps wore some of the earliest wool clothing.
He enjoyed mead, an alcoholic honey drink, and he raised cattle and drank their milk. He lived in a long house in a small farming community likely clustered near rivers.
Linguistic evidence suggests Kay worshipped a male sky god, sacrificed cows and horses in his honor, and lived in a village with respected chiefs and warriors. The average height for Yamnayan men was approximately 5-foot-9, and he likely had a heavily muscled frame from years spent toiling in his field. There is no other explanation. They believe the precise craftsmanship needed to construct a functional wheel and axle may have been impossible with stone tools. The first and most critical component of the wheel, writes Steven Vogel, author of Why the Wheel Is Round , is the fit with the axle.
Too tight and the wagon is hopelessly inefficient, too loose and the wheel wobbles and breaks apart. Too thick and the axle creates too much friction; too thin and it breaks under strain of the load. Then there would have been the matter of the wheel itself, which is a deceivingly complex device. Under strain, it would quickly deform. Kay would have had to carefully dowel these cuts together, and then shape them into a perfectly round wheel.
Too small and the wagon cannot surmount any potholes, too large and the already heavy vehicle becomes immobile. The wagon, as Anthony notes, could not have been put together in stages. Cattle began as wild aurochs before the late Natufians of Turkey domesticated them some 10, years ago. At first the Natufians used them exclusively for their meat and milk, but by the early fourth millennium BCE, the Maykop culture living in what is now Ukraine began to castrate the males and use them as work animals.
