⚠️ Disputed: the sources disagree.

What it is

The Santos-born priest petitioned King John V in 1709 for a privilege on a flying machine, the 'passarola', and is credited with a demonstration of a hot-air balloon at the Lisbon court. It is a disputed forerunner of aerostats.

Only the 1709 privilege is documented; the 8 August 1709 demonstration at the Casa da Índia and a manned flight of the 'passarola' lack solid contemporary evidence.

What it led to

  • Founding myth of Brazilian and Portuguese aeronautics
  • Historical memory prior to the Montgolfier balloons
