It took a long time for many achievements of the ancient world to be duplicated. The first city to reach one million people was Baghdad in 775 CE (or possibly Rome nine hundred years before), a feat that would not be duplicated until London and Beijing grew in the 19th century. The largest building in the world was the Great Pyramid for forty centuries until the 19th, and the world's current longest canal is over two millenia old. Some mysteries still remain, such as the formula of Greek Fire, but it looks like a different ancient weapon's secret has been discovered, that of Damascus steel. The key ingredient -- nanotech!
