presided over by a paramount chief, known as the Great Sun, who wielded absolute power. Both observers noted the high temple mounds which the Natchez had built so that the Great Sun could commune with God, the sun. His large residence was built atop the highest mound, from "which, every morning, he greeted the rising sun, invoking thanks and blowing tobacco smoke to the four cardinal directions". Archaeological surveys The most complete reference for these earthworks is Ancient Monuments of the Mississippi Valley, written by Ephraim G. Squier and Edwin H. Davis. It was published in 1848 by the Smithsonian Institution, which had commssioned the survey. Since many of the features which the authors documented have since been destroyed or diminished by farming and development, their surveys, sketches, and descriptions are still used by modern archaeologists. All of the sites which they identified as located in Kentucky came from the manuscripts of C. S. Rafinesque. Chronology Archaic era Radiocarbon dating has established the age of the earliest Archaic mound complex in southeastern Louisiana. One of the two Monte Sano Site mounds, excavated in 1967 before being destroyed for new construction at Baton Rouge, was dated at 6220 BP (plus or minus 140 years). Researchers at the time thought that such huter-gatherer societies were not organizationally capable of this type of construction. It has since been dated as about 6500 BP, or 4500 BCE, although not all agree. Watson Brake is located in the floodplain of the Ouachita River near Monroe in northern Louisiana. Securely dated to about 5,400 years ago (around 3500 BCE), in the Middle Archaic period, it consists of a formation of 11 mounds from to tall, connected by ridges to form an oval nearly across. In the Americas, building of complex earthwork mounds started at an early date, well before the pyramids of Egypt were constructed. Watson Brake was being constructed nearly 2,000 years before the better-known Poverty Point, and building continued for 500 years. Middle Archaic mound construction seems to have ceased about 2800 BCE. Scholars have not ascertained the reason, but it may have been because of changes in river patterns or other environmental factors. With the 1990s dating of Watson Brake and similar complexes, scholars established that pre-agricultural, pre-ceramic American societies could organize to accomplish complex construction during extended periods of time, invalidating scholars' traditional ideas of Archaic society. Watson Brake was built by
