 During his lifetime , Leonardo was valued as an engineer . In a letter to Ludovico il Moro , he claimed to be able to create all sorts of machines both for the protection of a city and for siege . When he fled to Venice in 1499 , he found employment as an engineer and devised a system of moveable barricades to protect the city from attack . He also had a scheme for diverting the flow of the Arno river , a project on which Niccolò Machiavelli also worked . Leonardo 's journals include a vast number of inventions , both practical and impractical . They include musical instruments , a mechanical knight , hydraulic pumps , reversible crank mechanisms , finned mortar shells , and a steam cannon .

 Leonardo is revered for his technological ingenuity . He conceptualised flying machines , a type of armoured fighting vehicle , concentrated solar power , an adding machine , and the double hull , also outlining a rudimentary theory of plate tectonics . Relatively few of his designs were constructed or even feasible during his lifetime , as the modern scientific approaches to metallurgy and engineering were only in their infancy during the Renaissance . Some of his smaller inventions , however , such as an automated bobbin winder and a machine for testing the tensile strength of wire , entered the world of manufacturing unheralded . A number of Leonardo 's most practical inventions are nowadays displayed as working models at the Museum of Vinci . He made substantial discoveries in anatomy , civil engineering , optics , and hydrodynamics , but he did not publish his findings and they had no direct influence on later science .

 Leonardo 's The Battle of Anghiara was commissioned in 1505 , but was lost . All that remains is a copy by Rubens , but Maurizio Seracini is convinced it can still be found and has spent a lifetime searching for it . He was allowed to drill some pilot holes in a mural in the Salone dei Cinquecento , Palazzo Vecchio , Florence , and his team did find evidence of an oil painting underneath .

 Leonardo da Vinci ( 1452 – 1519 ) was trained in anatomy by Andrea del Verrocchio . He made use of his anatomical knowledge in his artwork , making many sketches of skeletal structures , muscles and organs of humans and other vertebrates that he dissected .
