What did Leonardo da Vinci put on his resume?

Before he was famous, Leonardo da Vinci was a guy who needed a patron. And while we know him best as an artist, when he was 30, da Vinci thought his most marketable skills were those of weapons maker:

7. 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.

That said, in times of peace, da Vinci made it clear that he had some other talents, writing, “I can do in painting whatever may be done, as well as any other, be he who he may.”

Indeed.
