Uncolored etching of "The Flying Ship" proposed by the Jesuit Bartolomeu de Gusmão (1685-1724). On August 8, 1709, Gusmão is said to have flown a small balloon before the court in the Casa da Índia in Lisbon. The image in question may be a representation of a heavier-than-air machine proposed by Gusmão, or more likely, a representation of a proposed large balloon drawn by someone unfamiliar with the actual appearance of Gusmão's design. The craft is shown aloft with clouds and sun in the background. It features a bird-like shape and decorations. The operator sits in the open body of the bird with a telescope and globes. Oars are provided for propulsion.
