As he approached his thirtieth birthday, Leonardo had established his genius but had remarkably little to show for it publicly. His only known artistic accomplishments were some brilliant but peripheral contributions to two Verrocchio paintings, a couple of devotional Madonnas that were hard to distinguish from others being produced in the workshop, a portrait of a young woman that he had not delivered, and two unfinished would-be masterpieces.

Leonardo cast himself as an engineer because he was going through one of his regular bouts of being bored or blocked by the prospect of picking up a brush. As his mood swung between melancholy and exultation, he fantasized and boasted about being an accomplished weapons designer.
These boasts were aspirational. He had never been to a battle nor actually built any of the weapons he described. All he had produced thus far were some elegant sketches of concepts for weapons, many of them more fanciful than practical.

Some genuine, non-sarcastic questions:

- Why is this called art?
