The earliest remaining writings regarding levers date from the 3rd century BC and were provided by Archimedes. "Give me a place to stand, and I shall move the Earth with it" is a remark of Archimedes who formally stated the correct mathematical principle of levers (quoted by Pappus of Alexandria).
It is assumed that in ancient Egypt, constructors used the lever to move and uplift obelisks weighting more than 100 tons.
