For Germany in 1641, the court of King Ladislaus IV invited him to the Polish–Lithuanian Commonwealth. In Warsaw, Burattini built a model aircraft with four fixed glider wings in 1647.[2] Described as "four pairs of wings attached to an elaborate 'dragon'", it was said to have successfully lifted a cat in 1648 but not Burattini himself.[5] According to Clive Hart's The Prehistory of Flight, he promised that "only the most minor injuries" would result from landing the craft.[6]
Along with two others he met at Kraków, Burattini "performed optical experiments and contributed to the discovery of irregularities on the surface of Venus, comparable to those on the Moon".[15] He made lenses for microscopes and telescopes, and gave some of them to Cardinal Leopoldo de' Medici.[15] He is also credited with building a calculating machine, which he donated to Grand Duke Ferdinando II, that borrows from both a Blaise Pascal machine and Napier's rods.[16] He died in Kraków, aged 64.
