Folklore tells us of a chief of the Caddoan nation, a giant of a man, standing one day astride the Sabine River, with one foot each in the future states of Texas and Louisiana. He was studying the terrain southward; he had made his decision; he summoned his twin sons.
They had come of age; it was time for them to establish their own families. He instructed them to collect provisions, to canoe downriver for the time of one sun. Then to separate, one to proceed west, the other east, for the time of three suns, and there to claim the land for their pending tribes.
