Abu al-Qasim Abbas ibn Firnas ibn Wirdas al-Takurini, also known as Abbas ibn Firnas, latinized Armen Firman, was an Andalusian polymath: an inventor, physician, chemist, engineer, Andalusian musician, and Arabic-language poet. A pioneer of aviation, Ibn Firnas is reputed to have survived two successful flights. He was born in Ronda in the Takurunna province from Berber parents and lived in Córdoba. 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. His method of cutting rock crystal enabled Spanish mines to cutquartz, instead of exporting stones. He also designed the al-Maqata, a water clock. A statue of Ibn Firnas was built near the Baghdad Airport. The crater Ibn Firnas on the Moon is named in his honor, and one of the bridges over the Guadalquivir river in Córdoba was also named after him.
Work
Abbas Ibn Firnas designed a water clock called al-Maqata, devised a means of manufacturing colorless glass, invented various glass planispheres, made corrective lenses, devised a chain of things that could be used to simulate 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. He introduced the Sindhind to al-Andalus, which had important influence on astronomy in Europe.
Aviation
Some seven centuries after the death of Firnas, the Algerian historian Ahmed Mohammed al-Maqqari wrote a description of Firnas that included the following: 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, 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
Armen Firman may be the Latinized name of Abbas Ibn Firnas. According to some secondary sources, about 20 years before Ibn Firnas attempted to fly he may have witnessed Firman as he wrapped himself in a loose cloak stiffened with wooden struts and jumped 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 fallenough that he only sustained minor injuries. However, there is no reference to Armen Firman in other secondary sources, all of which deal exhaustively with Ibn Firnas' flight attempt. Armen Firman is not mentioned in al-Maqqari's account. As this story was recorded only in a single primary source, al-Maqqari, and 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.
