Giant crossbow

Inv. 6677
1952 - 1965

This the method for how the instrument looks that goes with the cord. And its releasecomes from the blow of that maul over the nut." "This makes the the same effect as the instrument above, except that its release is triggered with the lever, and its noiseless"

This crossbow was suggested as a major weapon of war and, in Leonardo's mind, it was to be employed for shooting large arrows against the enemy ranks and create havoc among them. In order to increase its flexibility and power, the gigantic bow, 24 metres wide, was to be manufactured in several lamellar sections. The shooting rope was stretched with a mechanical device and was then released by percussion or through the action of a lever. The six carriage wheels could be inclined, so as to ensure greater firing stability.

The model is based on the drawing:
