| Reverse description | Representation of the first invention of aerostation by Bartolomeu Lourenço de Gusmão (Santos, 1685 - Toledo, 1724), a religious and inventor born in Brazil. He was pejoratively called `the Glider` because of the disclosure in Europe of his inventions through fanciful drawings, which usually presented it as a bird-shaped boat. This invention became known as the Passarola (`Big Bird`). |
