Tribologists use the iconic image of Egyptians lubricating the logs used to move the large stones and stone carvings. To rival that -- archaeologists studying Stonehenge discovered that these ancient people may have used pig lard to lubricate sleds used to move the massive stones. Tribologists may need to think about ancient practices more.

According to the article written by
"Barney Harris, a doctoral student of archaeology at University College London, led a simulation of the greased sled theory. He and his volunteers showed that 10 people can move a 1-ton (0.9 metric tons) stone at nearly 1 mph (1.6 km/h).
The greased sled theory is also supported by examples of workers from other civilizations independently developing similar methods. Depictions from Mesopotamia and ancient Egypt show workers apparently using liquid lubricant to move large stone blocks, and an experimental archeologist working on Easter Island used mashed papaya to assist in moving large stones."
