Biography :  

He was born into a Muslim family in Ronda Tokoronna in the capital, led Kurra Banu Ifran in the reign of the Umayyads. Moreover, his ancestors participated in the conquest of the Iberian peninsula.

The biographers present him as a brilliant philosopher, so he received classical training from that time, which means it has made scientific studies and has been in contact with 
the remains of ancient sciences that Muslims of that time were compiling. He has studied chemistry, physics and astronomy.

His poetry skills and expertise in astrology allowed her to be introduced to the court of Abd ar-Rahman II (822-852) where he taught poetry.
But he continued to attend the court during the reign of the successor Muhammad I (852-886), it is for his many inventions, some of which are mentioned by historians. Ibn Firnas designed a water clock, the water clock called Al-Maqata Maqata modeled on that of Hero of Alexandria. It was also the first to develop the technique of size rock crystal in the Muslim world (for this he was credited with the invention of stone reading5 however Greeks already carved crystals from ancient and Emperor Nero already had an emerald cut to correct his myopia, it was therefore a rediscovery or application of ancient texts), which allowed especially not to cut import quartz imported via the Egypt. He designed an armillary sphere to see the movement of the stars and a planetarium that he built in lui6.

In 852 Ibn Firnas decided to fly by launching from a tower in Cordoba using a huge cloak to break his fall.

In 880, at the age of 70, he did make wooden wings covered with a silk coat he had stocked raptor feathers. He launched a tower overlooking a valley, and although the landing is bad (he fractured two ribs), he stayed in the air a while gliding. It was observed by a crowd that he had asked for in advance.

The historian of the seventeenth century, Al Maqqari, who reported this story, attributed his failure to the lack of a tail to his appareil6. He died seven years later, in 887. Leonardo followed a similar approach and rajouta a queue but the system devised really was not enough support surface to function properly and it will be the first gliders or Ader nineteenth century as those of Otto Lilienthal to see this concept inherited the legend of Icarus
