Renaissance age master-of-all-trades Leonardo da Vinci at one point appeared intent on pursuing a career well outside of the arts, if a letter he wrote to Ludovico il Moro, the Duke of Milan in 1482, while seeking employment, is anything to go by:
I will make covered chariots, safe and unattackable, which, entering among the enemy with their artillery, there is no body of men so great but they would break them. And behind these, infantry could follow quite unhurt and without any hindrance.
The letter is just one of many documents contained in the “Codex Atlanticus”, a 12 volume collection of da Vinci’s drawings and writings.
