Ibn al-Yasamin al-Ishbilli was one of the so many neglected, and yet accomplished scholars, who had a great impact on the science, an impact brought to general knowledge by the excellent entry on him by A. Djebbar, and out of which the following is derived. Ibn al-Yasamin (fl second half of the 12th century; d. 1204) comes originally form Norh Africa, of Berber descent, and, of Black skin, just as his mother was. He was according to the historian Ibn Said educated in Seville, including on the hands of Ibn Qasim al-Shalubin, who taught him algebra and the science of calculation, an education which was not restricted to mathematics since we know he also became famous in literature and poetry, and also was a legal expert. According to Ibn al-Abar, Ibn Yasamin wrote his famous algebraic poems in Seville, poems which in 1190 he was using in his teaching. Like most scholars of the time, Ibn al-Yasamin was a welcome visitor of the Almohad court, especially under Abu Yusuf Waqub (Al-Mansur) (ruled 1184-1199).
