Leonardo da Vinci was a great artist and ahead of his time inventor. Although he is best known for his unique and beautiful paintings, he had made great many inventions that proved to be marvelous basis for the scientists. Leonardo’s fascination with the surroundings helped him the most in his inventions.
The Giant cross bow is one of the most famous and awe-inspiring of his war inventions. He relied more upon the psychological effect of the Giant cross bow, rather than its physical work in the war field. He understood that fear can immobilize the enemy as effectively as the actual damage to the men. However the description provided by Leonardo da Vinci and the drawings tell the effort put by him to make it a realizable dream.
The pictorial representation of the Giant cross bow shows the intimidating specialty of this particular war invention. The crossbow if made into reality would measure around 27 yards across. 3 wheels on each side would have to be provided for mobility. The bow would be made of thin, flexible wooden pieces fitted together using pivoting pins and cords. The bow would be 13 meters wide with a very complex screw mechanism. Winches would be placed at the rear end for controlling the movement without slipping. These would play an additional role to lessen the required force for the tightening of the bow.
The Giant cross bow was designed to fire huge stones and bombs. Its function was dependent on a crank that would have to be spun by a soldier to pull back the bow and load it. A mallet would be used to knock the holding pin out and the weapon would be fired.
The drawing by Leonardo da Vinci makes the Giant cross bow look vividly alive and possible to be made into a terrifying war weapon. The Giant cross bow is a great example of the engineering genius of Leonardo da Vinci and his understanding of the thinking of war men. He knew what exactly was required by the army to win the war.
