Ibn al-Shatir (or Ibn ash-Shatir) ( 1304– 1375) was a Muslim astronomer of Damascus. He worked as timekeeper in the Umayyad Mosque there, and constructed a magnificent sundial for its minaret in 1371/72. His work kitab nihayat as-sul fi tashih al-usul ("A Final Inquiry Concerning the Rectification of Planetary Theory") in treating the motion of the Moon eliminated the need for an equant by introducing an extra epicycle, departing from the Ptolemaic system in a way very similar to what Copernicus later also did. Ibn al-Shatir proposed a system that was only approximately geocentric, rather than exactly so, having demonstrated trigonometrically that the Earth was not the exact center of the universe. Copernicus at one point used the same model as al-Shatir for removing equants; it remains controversial whether Copernicus was directly influenced by al-Shatir's work. ...more on Wikipedia about "Ibn al-Shatir"
