A parachute is a device used to slow the motion of an object through an atmosphere by creating drag. Parachutes are usually made out of light, strong cloth, originally silk, now most commonly nylon. Parachutes often take the shape of a dome, but shapes may vary including some taking the shape of an inverted dome. Depending on the situation, parachutes are used with a variety of loads, including people, food, equipment, space capsules, and bombs.
The earliest evidence for the parachute dates back to the Renaissance period. The oldest parachute design appears in an anonymous manuscript from 1470s Renaissance Italy (British Museum Add. MSS 34,113, fol. 200v), showing a free-hanging man clutching a cross bar frame attached to a conical canopy. As a safety measure, four straps run from the ends of the rods to a waist belt. The design is a marked improvement over another folio (189v), which depicts a man trying to break the force of his fall by the means of two long cloth streamers fastened to two bars which he grips with his hands. Although the surface area of the parachute design appears to be too small to offer effective resistance to the friction of the air and the wooden base-frame is superfluous and potentially harmful, the revolutionary character of the new concept is obvious

The Venetian polymath and inventor Fausto Veranzio (1551–1617) examined da Vinci's parachute sketch, and set out to implement one of his own. He kept the square frame, but replaced the canopy with a bulging sail-like piece of cloth that he came to realize decelerates the fall more effectively. A now-famous depiction of a parachute that he dubbed Homo Volans (Flying Man), showing a man parachuting from a tower, presumably St Mark's Campanile in Venice, appeared in his book on mechanics, Machinae Novae (1615 or 1616), alongside a number of other devices and technical conceptsa
