What was Leonardo da Vinci's suspended human-flight device called?

Leonardo da Vinci's suspended human-flight device was a parachute.

In a notebook entry from around 1485, Leonardo described a pyramid-shaped frame covered with linen. He wrote that a person could jump from a great height and descend safely with such a structure, provided it was sufficiently wide and deep.

Leonardo's design was not a modern parachute: it had a rigid wooden frame rather than a flexible canopy, and there is no evidence that he tested it. In 2000, British adventurer Adrian Nicholas built and tested a version based on the drawing. It produced a stable descent, although Nicholas switched to a conventional parachute before landing because the rigid design could be dangerous near the ground.

The concept shows Leonardo applying observation and geometry to air resistance long before parachutes became practical.
