Real lost high technology of ancient builders
Ancient cranes hold a significant place in the history of human civilization, playing a crucial role in the development of architecture, construction, and engineering.
These early cranes were essential in lifting heavy materials, such as stones and timbers, to great heights, enabling the construction of monumental structures like temples, pyramids, and cathedrals.
A 2nd century CE Roman marble relief from the tomb of the Haterii, a family of builders who were involved in the construction of public monuments. The relief shows a human powered treadwheel crane which could lift 6000 kg when worked only by 2 men.
Archeologists have uncovered evidence that the Ancient Greeks were the first to use cranes to lift heavy objects. These cranes, known as "polyspaston," were operated by a system of pulleys and ropes, allowing for the lifting of heavy loads with relative ease.
They predict that they were first in use in the 6th Century B.C, although I believe there is similar evidence to infer that they were used in all if not most even older megalithic stone constructions.
When observing various archaeological sites, they noticed that there were distinct markings that created grooves and holes in some of the stone structures. They surmised that these grooves and holes were created by some kind of lifting device (see photos). At this time, they were mostly used to lift heavy stone blocks when they were making temples.
