Read the passage from Indian Heroes and Great Chieftains, by Charles A. Eastman.

He [Crazy Horse] was an uncommonly handsome man. While not the equal of Gall in magnificence and imposing stature, he was physically perfect, an Apollo in symmetry. Furthermore he was a true type of Indian refinement and grace. He was modest and courteous as Chief Joseph; the difference is that he was a born warrior, while Joseph was not. However, he was a gentle warrior, a true brave, who stood for the highest ideal of the Sioux. Notwithstanding all that biased historians have said of him, it is only fair to judge a man by the estimate of his own people rather than that of his enemies.
