Mediaeval kites and Windsocks
Published online by Cambridge University Press: 04 July 2016
Extract
We have grown used to the idea that in the Middle Ages inventors produced several forerunners, either real or imaginary, of modern aerodynamic devices. The helicopter was designed, in principle, before Leonardo, while the rigid aerofoil, in the form of the plane-surface kite, achieved a remarkable degree of sophistication before the end of the sixteenth century. It has commonly been assumed that among these mediaeval inventions we should include some sort of three-dimensional kite, a precursor of Hargrave's box-kite, either in the form of a windsock equipped with wings, or in that of a primitive hot-air balloon, with or without additional lifting force provided by wings. I wish to examine the evidence for the existence of these objects, and to make a fresh assessment of the likelihood of their ever having flown.

The partial chronology given in Quarg, op cit, pp 7 ff, and in his introduction to the facsimile edition, Conrad Kyeser aus Eichstätt: Bellifortis, 2 vols, Düsseldorf, 1967, vol I, pp xxv-xxxii, is certainly faulty in several respects. Space is lacking here, however, to enter into the complex palaeographical issues involved.
