Oko iyawapi. In the Lakota language, oko iyawapi means "week count." In Lakota, Monday is Anpetu Tokahe (First Day) and Friday is Anpetu Zaptan (Day Five). The concepts of weeks and days of a week were unknown before nonLakotas arrived in Lakota country. The naming convention for the days of a week appear to follow the Christian system wherein the world was created in six days and the seventh day God rested; and followers ever since are to set aside their work and attend church that day. In Lakota, Sunday is Anpetu Wakan (Sacred Day). The Lakota week is seven days, begins on Monday and ends on Sunday. This is the convention that is used for this oko iyawapi.
This oko iyawapi is organized around a photo taken each week at Wingsprings, beginning the week of February 23 to March 1, 2009. It is based on a traditional waniyetu iyawapi, or "winter count," like the detail of one drawn by High Hawk shown above. But whereas Lakota winter counts were added to annually, this oko iyawapi is added to weekly. Soon you may click the image of the windsock to go to the weekly posts.
