Life
Giovanni Fontana (ca. 1395 to ca. 1455) was fifteenth-century Venetian physician and engineer who portrayed himself as a magus. He was born in Venice in the 1390s and attended the University of Pauda, where he received a his degree in arts in 1418 and his degree in medicine in 1421. University records list him as "Master John, son of Michael de la Fontana." . His most famous promoter at the University was the famous scholastic Paul of Venice. He tells us that the Doge of Venice sent him to Brescia to deliver a message to the condottiere Francesco Carmagnola. He was also employed as the municipal physician by the city of Udine.

Works
Fontana composed treatises on a diverse array of topics. We have early works of his on water-clocks, sand-clocks and measurement. Fontana composed one of the earliest Renaissance technological treatises, Bellicorum instrumentorum liber. His machine book contains siege engines and fantastic inventions such as a magic lantern and a rocket-propelled bird, fish, and rabbit.
