of levers, which rested on the shoulders of the man who guided it, and who could move them alternately by means of his hands and feet. The following description of the machine is given in the Journal de Paris by an eye-witness:—
"The 'wings' are oblong frames, covered with taffeta, and attached to the ends of two rods, adjusted on the shoulders. The wings work up and down. Those in front are worked by the hands; those behind by the feet, which are connected with the ends of the rods by strings. The movements were such that when the right hand made the right wing descend in front, the left foot made the left wing descend behind; and in like manner the left hand in front and the right foot behind acted together simultaneously. This diagonal action appeared very well contrived; it was the action of most quadrupeds as well as of man when walking; but the contrivance, like others of the same kind, failed in not being fitted with gearing to enable the air traveller to proceed in any other direction than that in which the wind blew him. The inventor first flew down from a stool, then from a table, afterwards from a window, and finally from a garret, from which he passed above the houses in the neighbourhood, and then, moderating the working of his machine, he descended slowly to the earth."
Tradition records that under Louis XIV. a certain rope-dancer, named Alard, announced that on a certain day he would perform the feat of flying in the air. We have no description of his wings. It is recorded, however, that he set out on his adventurous flight; but he had not calculated all the necessities of the case, and, falling to the ground, he was dangerously hurt.
Leonardo da Vinci might have known the art of flying in the air, and might even have practiced it. A statement to
