Previously I had talked about an amazing piece of computational engineering from the ancient world, the Antikythera mechanism, which was also posted up at A Tippling Philosopher. In the comments there, a discussion came up about another wonder of antiquity which has attracted all sorts of speculations among alternative thinkers. This is the construction of the temple complex at the city of Baalbek, also known as Heliopolis, in modern-day Lebanon, about 70 kilometers* north of Damascus. The site has considerable antiquity, but it is the large stones at the temple, especially the three known as the Trilithon, that have garnered the greatest attention, each weighing in around 800 tons.* And deservedly so, as they are some of the largest single objects ever moved in the pre-modern era.
