The oldest tank design was created by the Italian artist and inventor, Leonardo da Vinci (1452-1519), who draughted and tested some innovative inventions, amongst which were early concepts for a tank. There was provision for outward facing guns, and the whole machine was covered in wood for protection. It was designed for locomotion with wheels rather than tracks such as those fitted to modern tanks, hence it would have been very difficult and cumbersome to manoeuvre. Although the tank was never actually built, however a model of it was constructed for display in early 2007 at Sofia City Art Gallery, Bulgaria.
