Leonardo da Vinci was a military architect and engineer.
The son of Pope Alexander VI, Cesare Borgia, hired Leonardo da Vinci at the end of his life to produce a map of Imola, a city Cesare had just seized. Cesare Borgia served as the papal army's chief commander and was renowned for his harsh methods of maintaining authority and attempting to subjugate other Italian republics.
For ten months, Leonardo worked as a "senior military architect and general engineer." In order to conduct a study of Borgia's various domains, he journeyed across them. Furthermore, he produced a large number of topographic maps and city layouts that predated contemporary mapping.
It was common practice during the period to overstate the significance of specific structures, such as chapels, in order to make them stand out from the surrounding structures. Leonardo used the technique of paper vedere, his understanding of geometry, and a compass to precisely measure street lengths and building proportions in order to create a more realistic representation of the city. The most typical kind of map is one created in this manner, known as an ichnographic map.
One of the interesting facts about Leonardo is that he was an excellent designer. In addition to developing the double hull and a basic theory of plate tectonics, he also created an armored automobile, a scythed chariot, a pile driver, a revolving crane, a pulley, a lagoon dredge, a flying ship, concentrated solar power, and an adding machine.
