HISTORY II 

THE PORTUGUESE PRIEST - 1709

Father Bartolomeu de Gusmão Bartolomeu de Gusmão, a Jesuit priest, was a major figure in aerostatics and is renowned for the bird-shaped balloon he built and which was named "Passarola". Gusmão was born in 1685 in Santos, Brazil, then property of the Portuguese crown. He attended the Jesuit seminary of Bahia and soon showed an interest and a talent for Physics; he invented and patented a machine to elevate water up to 100 m high. Having completed his studies in Brazil, he embarked to Portugal in 1705, and joined Coimbra University in 1708 where he studied Physics and Mathematics. Soon he started working on a "lighter than air" device, and in 1709 King João V granted him a patent for his "air-walking object". The crown also decided to help him out with the expenses to build the machine and the king graciously granted him an allowance for life. Free from financial worries, Bartolomeu was then able to dedicate himself completely to his endeavours with the technology available at the time, and there is evidence that wire-braced paper balloons were used in his experiments.

Experimental Paper BalloonOn 8 August 1709, in “Casa da India”, Gusmão made a hot-air filled paper balloon ascent 4 meters in the presence of the court, the Ambassadors, and religious dignitaries, among whom was Cardinal Conti (later Pope Innocent XIII). The hot air was produced by “fire burning in a clay bowl nested in a wooden tray at the bottom of the balloon.” Fearing that the curtains would catch fire, the servants destroyed the balloon, but the experiment was a success.

PassarolaBartolomeu de Gusmão proceeded with his experiments with larger balloons and the legend has it that eventually he himself flew a balloon which was launched from St. Jorge Castle, on top of one of Lisbon’s seven hills, covered 1 km, and crashed in Terreiro do Paço. This bird-shaped balloon was to become known as the “Passarola”, but following this feat, Gusmão’s fortunes seemed to have waned. Intrigue and jealousy made him fall from grace and, when he was black-listed by the Inquisition, he found sanctuary with the Jesuits who sent him to Spain in 1724, where he eventually died in total destitution.
