I did some reading on teh Osage Indians. Here is just a little bit of what I learned.
The Osage Indians are a people with a rich history. They refer to themselves as the Wazhazhe. When Europeans first met the Wazhazhe, using rough French phonetics, they translated the name of one division of the tribe, the Wazhazhe, into the word "Osage." Osage has been the name that the European-Americans have used to identify the tribe.
The Osage also called themselves by their ancient name, NiuKonska, which may be translated as "Little Ones of the Middle Waters." The traditional history of the Osage puts them in the Mississippian culture situated in central and eastern North America, existing for thousands of years before the Europeans arrived. The Osage lived in permanent villages along the Missouri and Osage Rivers in Missouri, building hunting camps on the Great Plains. The tribe grew corn, squash, and pumpkins to supplement the buffalo and venison, the mainstay of their diet. The Osage developed a highly complex culture that reflected an intellectual tradition equally sophisticated and imaginative as any in Europe.
That's for sharing your coin and for the history lesson.
