A fascinating story, part legend, part fiction, might be told of the earliest reputed inventors. The fable of Daedalus perhaps grew up round the memory of a man of mechanical genius, for Daedalus was the author of many inventions before he flew from Crete to Italy. Aulus Gellius, in his entertaining book of anecdotes called the _Attic Nights_, tells how the philosopher Archytas of Tarentum invented a mechanical pigeon, which was filled with some kind of light air, and flew. The two schools of aeronautics were here reconciled. Other mechanists were Roger Bacon, who is reported to have designed a flying chariot; and Regiomontanus, astronomer and mathematician, who made a mechanical eagle which flew to meet the Emperor Charles the Fifth, on his solemn entry into the city of Nuremberg. It is not necessary to inquire whether these stories are true or false; what is certain is that the inventors did not leave their inventions as a legacy to their fellows. For a like reason Leonardo da Vinci, who busied himself with a mechanism which should enable man to operate wings with his legs, and who left a short treatise on the art of flight, has no place in the history. His mechanism is merely a drawing; his treatise remained in manuscript. The adventurers who risked their lives on wings of their own making are truer ancestors of the flying man. In 1507 John Damian, who was held in esteem as an alchemist and physician at the court of King James IV of Scotland, 'took in hand to fly with wings, and to that effect he caused make a pair of wings of feathers, which being fastened upon him, he flew off the castle wall of Stirling, but shortly he fell to the ground and brake his thigh-bone'.[1] The poet Dunbar attacked him in a satirical poem, and the reputation of a charlatan has stuck to him, but he deserves credit for his courageous attempt. So does the Marquis de Bacqueville, who, in 1742, attached to his arms and legs planes of his own design, and launched himself from an upper story of his house in Paris, in the attempt to fly across the river Seine to the Tuileries, about two hundred yards away. He glided some distance, and then fell on a washerwoman's barge in the stream, breaking his leg in the fall. These and other disastrous attempts might be defended in the words of Wilbur Wright, written in 1901, while he was experimenting with his own gliders. 'There are two ways', he says, 'of learning how to ride a fractious horse: one is to get on him and learn by actual practice how each motion and trick may be best met; the other is to sit on a fence and watch the beast awhile, and then retire to the house and at leisure figure out the best way of overcoming his jumps and kicks. The latter system is the safest; but the former, on the whole, turns out the larger proportion of good riders. It is very much the same in learning to ride a flying machine; if you are looking for perfect safety you will do well
