Abu al-Qasim Abbas ibn Firnas ibn Wirdas al-Takurini (Arabic: أبو القاسم عباس بن فرناس بن ورداس التاكرني; c. 809/810 – 887 CE), known as Abbas ibn Firnas (Arabic: عباس ابن فرناس) was an Andalusi polymath: an inventor, astronomer, physician, chemist, engineer, Andalusi musician, and Arabic-language poet. He was reported to have experimented with unpowered flight.
Ibn Firnas made various contributions in the field of astronomy and engineering. He constructed a device which indicated the motion of the planets and stars in the Universe. In addition, Ibn Firnas came up with a procedure to manufacture colourless glass and made magnifying lenses for reading, which were known as reading stones.




Origin


Abbas ibn Firnas was born in Ronda, in the Takurunna province and lived in Córdoba. His ancestors participated in the Muslim conquest of Spain. His full name was "Abu al-Qasim Abbas ibn Firnas ibn Wirdas al-Takurini", although he is better known as Abbas ibn Firnas. There is very little biographical information on him. While the majority of sources describe him as a Umayyad mawlā (client) of Berber origin, some sources describe him as Arab.




Work


Abbas ibn Firnas devised a means of manufacturing colourless glass, invented various glass planispheres, made corrective lenses ("reading stones"), devised an apparatus consisting of a chain of objects that could be used to simulate the motions of the planets and stars, and developed a process for cutting rock crystal that allowed Al-Andalus to cease exporting quartz to Egypt to be cut. He introduced the Sindhind to Al-Andalus, which had important influence on astronomy in Europe. He also designed the al-Maqata, a water clock, and a prototype for a kind of metronome.




Aviation


Some seven centuries after the death of Firnas, the Algerian historian Ahmad al-Maqqari (d. 1632) wrote a description of Ibn Firnas that included the following:

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 Ibn Firnas, he does not cite his sources for the details of the reputed flight, though he does claim that one verse in a ninth-century Arab poem is actually an allusion to Ibn Firnas's flight. The poem was written by Mu'min ibn Said, a court poet of Córdoba under Muhammad I (d. 886), amir of the Emirate of Córdoba, 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.
It has been suggested that Ibn Firnas's attempt at glider flight might have inspired the attempt by Eilmer of Malmesbury between 1000 and 1010 in England, but there is no evidence supporting this hypothesis.




Armen Firman


According to some secondary sources, about 20 years before Ibn Firnas attempted to fly he witnessed a man named Armen Firman wrap himself in a loose cloak stiffened with wooden struts and jump from a tower in Córdoba, intending to use the garment as wings on which he could glide. The alleged attempt at flight was unsuccessful, but the garment slowed his fall enough that he sustained only minor injuries.
However, other secondary sources that deal exhaustively with Ibn Firnas' flight attempt make no reference at all to Armen Firman. Al-Maqqari's account of Ibn Firnas, being the sole primary source of the flight story, makes no mention of Firman. Since Firman's jump is said to have been Ibn Firnas' source of inspiration, the lack of any mention of Firman in Al-Maqqari's account may point to synthesis—the tower jump later confused with Ibn Firnas' gliding attempt in secondary writings. In fact, it is likely that Armen Firman is simply the Latinized name of Abbas ibn Firnas.




Legacy


In 1973, a statue of Ibn Firnas by the sculptor Badri al-Samarrai was installed at the Baghdad International Airport in Iraq.
In 1976, the International Astronomical Union (IAU) approved of naming a crater on the moon after him as Ibn Firnas. In 2011, one of the bridges going over the Guadalquivir river in Córdoba, Spain, was named the "Abbas ibn Firnás Bridge". A British one-plane airline, Firnas Airways, was also named after him.
