Mansur Ibn Talha Al Tahiri

Mansur ibn Talha ibn Tahir ibn al-Husayn. Ibn al-Nadim says that Abdallah ibn Tahir called him the judge of the house of Tahir and admired him, and that he governed Marw, Amul and Khwarazm. ²

He has well-known books on philosophy, among them al-Mu'nis on music, which al-Kindi read and said that it was indeed a companion, as its author called it. He also wrote al-Ibana 'an Af'al al-Falak (Clarification on the Actions of the Sphere), al-Wujud (Existence), a treatise on number and the numbered, and al-Dalil wa al-Istidlal (The Proof and the Inference). ²
