Attempts at Flying from Encyc. Brit. I, p. 186.
1617 Fleyder, rector of grammar school at Tubingen, delivered a lecture on flying, which he published eleven years afterwards. A poor monk, ambitious to reduce this theory to practice, provided himself with wings; but machine broke down — and falling to ground he broke his legs and perished.
Elmerus (A monk about Confessor's time) flew by means of wings from a town a distance of more than a furlong.
Another person — flew from St. St. Mark's steeple at Venice
And another — at Nuremburg
A Turk — at Constantinople
Possible to make a long list of such narrations.
1680–81 Borelli's posthumous work De Motu Animalium points out impossibility of man being able by his muscular strength to give motion to wings of sufficient extent to keep him suspended in the air.
From Encyc. Brit. I, 186.
Albert of Saxony , Monk of order of St. Augustine, and commentator on works of Aristotle.
“As fire is more attenuated, and floats above our atmosphere, therefore a small portion of this etherial substance, enclosed in a light balloon globe, would raise it to a certain height, and keep globe, would raise it to a certain height, and keep it suspended in the air; and that, if more air were introduced, the globe would sink like a ship when water enters by a leak”.
