Tertius Chandler (1915–2000) was an American historian and author known for his extensive work on history, economics, and religion, particularly his intriguing theories about Moses. His most renowned work, "Four Thousand Years of Urban Growth" (1987), gained recognition among scholars for its estimates of ancient city populations. However, it has also faced criticism from urban historians for its superficial and uncritical use of sources, leading to potentially unreliable population estimates.Apart from his mainstream historical research, Chandler delved into alternative ideas about history, which he detailed in his book "Godly Kings and Early Ethics." These ideas included his belief that figures in Greek mythology, such as Zeus, were actual historical figures, and that Moses had significant influence on various cultures and civilizations.Throughout his career, Chandler authored several other notable books, including "Chandler's Half Encyclopedia," "The Tax We Need," "Remote Kingdoms," and "Moses and the Golden Age."His thought-provoking theories and extensive body of work have left a lasting impact on the field of historical research and continue to spark discussions and debates among scholars and enthusiasts.Keywords: Tertius Chandler, historian, author, Four Thousand Years of Urban Growth, Moses, alternative history, Zeus, Greek mythology, historical theories, urban populations, literature.
