00:00if ancient egypt is known for one thing it's the pyramids and the pyramid of joser constructed 4500
00:09years ago at the necropolis of sakara is particularly amazing that's because no one
00:14knew how the ancient builders would have been able to construct such an achievement but
00:17researchers believe they may have just figured it out archaeologists have recently uncovered
00:21what they believe is a former dam one they say could have helped the egyptians move giant stones
00:26experts detail that the dam likely powered a lift and another find at the site corroborates this
00:31theory they say that device may have used hydraulics featuring a central shaft which could have been
00:36filled with water to lift large objects with the researchers writing based on a transdisciplinary
00:41analysis this study provides for the first time an explanation of the function and building process
00:46of several colossal structures found at the sakara site the period in which the pyramid of joser was
00:52built was a turning point for the egyptian civilization as a whole this is when they
00:56first began constructing massive tombs for their dead royalty experts add that while this hydraulic lift
01:01hypothesis is sound they will need to collect more evidence to be sure the theory holds water
