Gusmao's Passarola airship,1709
Gusmao's Passarola airship. Historical artwork of the Passarola airship design that was proposed in 1709 by the Portuguese priest and naturalist Bartolomeu de Gusmao (1685-1724). Gusmao presented this design to King John V of Portugal,and was awarded a professorship of mathematics at the University of Coimbra,and a lifetime's pension to support his work on the design. The design was similar to that of a kite,with the upper canopy intended to provide lift from either the wind,or a set of bellows. A scheduled public test never took place,but Gusmao is reported to have tried descending from hilltops with similar designs. Artwork from Astra Castra (Hatton Turner,London,1865)
