1714 sketch by the Swedish scientist Emanuel Swedenborg
Swedenborg's Flying Machine was first sketched by the Swedish scientist Emanuel Swedenborg in 1714, when he was 26 years old.[4][5][6][7] It was later published in his periodical, Daedalus Hyperboreus, in 1716. While Leonardo da Vinci’s designs predate those of Swedenborg, da Vinci’s manuscripts remained unknown due to a variety of circumstances until the late 19th century.[8][9] So, in terms of influence, Swedenborg predated da Vinci.
