According to the website Gizmodo, recent research shows that ancient Greeks used primitive types of hoists to move heavy stones before they started using cranes 2,500 years ago.

The most important discovery of the ancient Greeks Building technology It was a crane. Nevertheless, it was known that a huge stone structure was built in Greece at least 150 years before the crane itself was used.

According to a survey Athens British School AnnualThe crane first appeared in the second half of the 6th century BC, but its mechanical pioneers were Temple With Ismia Corinth At least 150 years ago, around the middle of the 7th century BC.

Researchers say that the ancient Greeks most likely first used a ramp made of soil or mudbrick to lift the heavy stone blocks used in the main construction. The lifting device is believed to have been similar to that used by the ancient Egyptians and Assyrians centuries ago.

The predecessor of the crane lifter

Written by Alessandro Pieratini, an assistant professor of architecture at the University of Notre Dame, this paper is the next pioneer of cranes in which a type of lifter used by the ancient Greeks can lift heavy cut stone blocks. Claimed to have been 200-400 kilograms (440-880 pounds).

The lifter was originally invented by the Corinthians. The Corinthians used it to build ships and drop heavy sarcophagus into a narrow, deep burial pit. It wasn’t a crane because it didn’t use a winch or hoist. Instead, the builder used a rope that passed over the frame to redirect the force of the weight.

“This type of masonry represents an important step in the development of Greek monumental stone architecture, both the construction of mudbrick, which was the standard for most Greek buildings, and previous stone experiments. It shows a deviation from, “writes Pieratini.

The first documented use of liver in the Greek temple

Evidence of this device is believed to be a ditch carved into the bottom of the stone used to build the Corinthian and Ismia temples. These ditches are well known to historians, but until now it was unclear whether the ditches were the result of lifting the blocks during the construction process or the result of moving the blocks in the quarry. ..

For research, Pieratini studied the stone blocks used in the early Greek temples, and at the same time was involved in several experimental archeologies. He studied the blocks of the mid-7th century temples in Corinth and Ismia and their unique markings. Two parallel rope grooves are cut down and one end is up.

Using real stones and ropes, Pierattini discovered that the ditch doubles as a function, allowing the builder to lift the block and place it firmly against its neighbors along the walls of the building.

“Due to the high friction between the heavy stone block and the surface of the stone, this is a very problematic construction stage and will require a set of dedicated holes for later use of the metal lever,” Pierattini said. Says.

“This paper shows that the builders of the early temples of Corinth and Ismia had already used the liver for the final setting of the block. This is the first documented use of the liver in Greek architecture. It represents the law, “the professor explained to Gizmode.
