Nestled in the southern section of modern-day Nigeria are the remnants of a civilization so vast that one of its crowning achievements has never been matched by any civilization that has ever existed on the planet--including all modern societies. Archeologically known as the Ancient Linear Earthworks of Benin and Ishan, the Great Wall of Africa, also known as the Great Wall of Benin is almost 10,000 miles long and at some points reaches more than 60 feet in height. Even though it holds a place in the 1982 Guinness Book of World Records as the most massive structure that has ever been constructed, almost no one outside of a select few archeologists and specialists has heard of its enormous breadth. This book attempts to change that forever.The Great Wall of Africa or Great Wall of Benin actually consists of a series of linear earthworks, many of them circular, some straight, some which stand on their own, and others that interconnect across a large area of Southern Nigeria. The Great Wall of Africa, like the Great Wall of China, is not a single wall, but a series of separate walls. Until the writing of this book, and another that I authored called: From Man To Superman: Dr. John Henrik Clarke vs. Herman Cain, the Great Wall of Africa, which stretches 9,941 miles long, was known popularly among African scholars as the Walls of Benin. However, as I shall show, like the Great Wall of China, they were created by a single civilization, and therefore, constitute one major wall system. Surprisingly, Benin is an area that cultural anthropologists, known as ethnographers have taken time to study and have written about extensively. However, as Dr. Ivan Van Sertima pointed out in one of his lectures, one of the great flaws of scholarship on Africa is that: "Anthropology has for a long time had a love affair with the primitive... man living on the edge of the world... The Great Wall of Africa consists of the Great Walls of Benin which are called Iya by the Beni people. To understand the enormity of The Great Wall of Africa, one must consider the magnitude of earth displaced to construct it. The Great Wall of Benin contains more than 100 times the material of the Great Pyramid of Egypt (Pharaoh Khufu's Pyramid). This is no minor feat because the Great Pyramid is a massive structure, containing more stone than 30 Empire State buildings. In all, more than 9.1 billion cubic feet of earth was used to build the Great Wall of Benin over an 800-year time period. The average height of each wall is 3 meters or just under 10 feet high, however, some of the Iya tower almost 60 feet in height (18 meters). The Iya cover more than 2,500 square miles of land area. This massive effort took more than 150 million man-hours to construct. Simply put, if all of the material was taken from all of the buildings on New York City's borough of Manhattan, there would not be enough substance to build the Great Wall of Africa. The Great Wall of Africa contains more material than all of the financial district's buildings, all of midtown Manhattan's buildings and all of uptown Manhattan's buildings (Harlem) combined.The ancient Bini and Ishan people, the people of the Benin Empire, who built their wall, had no bulldozers, cranes or other equipment from the Caterpillar Corporation. They had no backhoe loaders, articulated trucks, or asphalt pavers... What they had was in many ways more impressive than all of these things. They were standing on the history of a continent that built 4,500 year-old pyramids that were 48 stories high, smelted carbon steel 2,000 years before the present, sent 2,400 ships to America 181 years before Christopher Columbus, produced the first universities in the world, understood how to perform surgery on the eye to remove cataracts 700 years ago, and that had charted star systems that were not discovered by Europeans and Americans until the Einstein Orbiting Satellite observed them in 1996.
