Airship

In 1709, he presented a petition to King João V of Portugal, seeking royal favour for his invention of an airship, in which he expressed the greatest confidence. The contents of this petition have been preserved, together with a picture and description of his

, S.J., Gusmão wanted to spread a huge sail over a boat-like body like the cover of a transport wagon; the boat itself was to contain tubes through which, when there was no wind, air would be blown into the sail by means of bellows. The vessel was to be propelled by the agency of magnets which were to be encased in two hollow metal balls. The public test of the machine, which was set for 24 June 1709, did not take place. It is known that Gusmão was working on this principle at the public exhibition he gave before the Court on 8 August 1709, in the hall of the

. He was also one of the fifty selected as members of the ''Academia Real de História'', founded in 1720; and in 1722 he was made chaplain to the Court. Gusmão also busied himself with other inventions, but in the meantime continued his work on his airship schemes, the idea for which he is said to have conceived while a novice at Bahia. His designs included a ''ship to sail in the air'' consisting of a triangular gas-filled pyramid, but he died without making progress.


Persecution

It dates, however, from at least the end of the 18th century, as the following article in the London ''Daily Universal Register'' (later ''The Times'') of 20 October 1786, makes clear: Contemporary documents do attest that information was laid before the Inquisition against Gusmão, but on quite another charge.

He wrote: ''Manifesto summário para os que ignoram poderse navegar pelo elemento do ar'' (''Short Manifesto for those who are unaware that is possible to sail through the element air'', 1709); and ''Vários modos de esgotar sem gente as naus que fazem água'' (''Several ways of draining, without people, ships that leak water'', 1710); some of his sermons also have been printed.
