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.
Al-Maqqari is said to have used in his history works "many early sources no longer extant", but in the case of Firnas, he does not cite his sources for the details of the reputed FLIGHT, though he does claim that one verse in a 9th-century Arab poem is actually an allusion to Firnas's FLIGHT. The poem was written by Mu'min ibn Said, a court poet of Córdoba under Muhammad I (d. 886), who was acquainted with and usually critical of Ibn Firnas. The pertinent verse runs: "He flew faster than the phoenix in his FLIGHT when he dressed his body in the feathers of a vulture." No other surviving sources refer to the event.
