Ibn Firnas designed a water clock called Al-Maqata, devised a means of manufacturing colorless glass, made corrective lenses ("reading stones"), developed a chain of rings that could be used to display the motions of the planets and stars, and developed a process for cutting rock crystal that allowed Spain to cease exporting quartz to Egypt to be cut.
Ibn Firnas once asked himself in a personal ledger:
"What man-made machine will ever achieve the complete perfection of even the goose's wing?"5
In 875, at age of 65 years, and perhaps inspired by the earlier attempt at flight by Armen Firman, Ibn Firnas made his first attempt at flight using a rudimentary glider and launched from the Mount of the Bride (Jabal al-'Arus) in the Rusafa Area, near Córdoba, Spain. However, it ended in a crash and he injured his back. This failure left critics saying he hadn't taken proper account of the way birds land and that he had provided neither a tail, nor a means for landing.65
Ibn Firnas died twelve years later in 887, at the age of 77.
Eyewitness accounts
Several eye witnesses reported the event. Ibn Firnas stated the following, moments before he flew:
"Presently, I shall take leave of you. By guiding these wings up and down, I should ascend like the birds. If all goes well, after soaring for a time I should be able to return safely to your side."5
"Having constructed the final version of his glider, to celebrate its success he invited the people of Cordoba to come and witness his flight. People watched from a nearby mountain as he flew some distance, but then the glider plummeted to the ground causing him to injure his back..."
Another account states:
"We thought ibn Firnas certainly mad ... and we feared for his life!"5
Another witness, the poet Mu'min Ibn Said (d. 886), reported:
"He flew faster than the phoenix in his flight when he dressed his body in the feathers of a vulture."65
Based on these and other eyewitness accounts, the early 17th-century historian Ahmed Mohammed al-Maqqari described the event as follows:
"Among other very curious experiments which he made, one is his trying to fly. He covered himself with feathers for the purpose, attached a couple of wings to his body, and, getting on an eminence, flung himself down into the air, when according to the testimony of several trustworthy writers who witnessed the performance, he flew a considerable distance, as if he had been a bird, but, in alighting again on the place whence he had started, his back was very much hurt, for not knowing that birds when they alight come down upon their tails, he forgot to provide himself with one."6
Ibn Firnas' flight was apparently the inspiration for Eilmer of Malmesbury, more than a century later, who would fly in England for about 200 meters using a glider circa 1010.8
According to Paul Lunde, "had he lived in the Florence of the Medici, Abbas ibn Firnas would have been a Renaissance man."9
