Abu al-Qasim Abbas ibn Firnas ibn Wirdas al-Takurini (809–887 A.D.), also known as Abbas ibn Firnas (Arabic: عباس بن فرناس‎), 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 cut quartz, instead of exporting stones. He also designed the al-Maqata, a water clock.
