A Pipestone Pipe, also called a peace pipe, calumet or medicine pipe is a ceremonial smoking pipe used by many native American tribes, traditionally as a token of peace. The most common and sacred thing smoked was tobacco. A prayer would be said to each of the four directions as well as ‘Mother Earth’ and ‘Father Sky’ as they filled the pipe. Also, some tobacco would be sprinkled on the ground. To show respect, smoke would be blown into one’s face. Captives would, at times, take this the wrong way, but it was actually a sign of kindness or respect.
