All work, no rest
The Architect for the Great Pyramid of Giza was Pharaoh Khufu’s vizier, but he didn’t lift a finger in any of the work. When the Pyramid was first constructed, it measured at 146.5 meters, in comparison to today’s remains at 138.8 meters.
After extensive research by historians, it was found that in order for the Pyramid to be built within the 20 year time frame, it would have worked out that slaves placed 12 blocks per-hour. Truly back breaking work.
