They lived in “beehive” style houses made of a framework of poles covered with thatched grass. These were generally grouped about an open space where social and ceremonial gatherings would be held. Food was cooked in vessels of pottery, and baskets of varying sizes which were skillfully made. Plant fibers were woven, and the cloth was made into garments. Other clothes were made from animal skins, including the buffalo, for winter use. Besides having the usual ornaments for the arms, neck, and ears, the Caddo often wore nose rings and practiced tattooing. Descent was traced through the mother and chieftainship was hereditary, as was the custody of certain sacred articles used in religious ceremonies.
