Here's an amusing collection of Dakota-Sioux fables, often featuring the vain and mischievous imp Iktomi. Fables such as these were told to Dakota-Sioux children for entertainment but also to teach through negative example the importance of honor, modesty, manners, and other aspects of a noble Indian lifestyle.
