Engineer (1729 – 1781)
A giant of engineering, Marinos Charbouris, also known as Charvouris, was born in Argostoli of Cephallenia which was under the rule of the Venetian Republic. He studied mathematics in Bolognia and engineering in Bonn. In 1761 he joined the army of Maria Theresa , ruler of the Habsburg Monarchy, and subsequently the army of Catherine the Great as an engineer.
However, Charbouris is not known for his studies nor for his services in any army. He is known as the man to have moved the heaviest object in history at the time; a 2.000 ton monolith over a distance of 20 kilometers using a system of advanced engineering and mechanics.
Around 1770, Catherine the Great wanted to erect a statue of Peter the Great at the centre of Saint Petersburg, Russia. Other engineers suggested using smaller rocks to assemble a large one, a plan that would fail because the rocks would not sustain the statue itself. Charvouris was informed of a massive monolith lying in Finland and went to study it himself. After informing the empress of the monolith, fellow engineers mocked Charbouris for believing it was an impossible feat. Charbouris managed to persuade the empress and in 1770 he set out to achieve the impossible.
Around the rock in Finland, Charbouris assembled a workforce of 400 workers and created a small village. He created 12 enormous cranes which were used to lift the boulder and place it unto a mattress of grass. The boulder was passed on a series of grills which would be used to transport it. To achieve the transportation, Charbouris used two large beams adjacent to each other like rails with bronze spheres on top. Over these male grips were placed the female grips – two other beams without spheres. The boulder was placed on top of this contraption so that when the workers pulled, the spheres underneath would slide the massive rock. Carts full of tools were transported along with the boulder while a drummer stood atop of it to give the men the rhythm of movement. Every now and then the boulder would stop moving and more beams would be placed in front so as to continue the transportation.
In order to turn the boulder left or right to he right direction Charbouris came up with another engineering feat. He created two round impellers which one on top of the other with bronze spheres in the middle, similarly to the beams he used. Simultaneously, Charbouris created a dock which functioned as a swimming pool, being able to pump water in and out so that the boulder wouldn’t sink.
The boulder arrived successfully in St. Petersburgh where Charbouris and his men were greeted with applause and cheers from the people. Scrulptor Étienne Maurice Falconet would work on the boulder to erect the statue of Peter the Great. Charbouris greatest feat as he himself claimed was that all of his 400 men returned alive and safe. For his work Catherine the Great appointed him Lieutenant-Colonel of the Russian school of officers. In 1779 he returned to Cefalonia where he drained large areas of land using state-of-the-art engineering to cultivate cotton, sugar canes and indigo to great success. Charbouris’s monumental work remains an astonishing engineering feat to this day.
