Avicenna was even raised to the office of vizier; but the turbulent soldiery, composed of Kurds and Turks, mutinied against their nominal sovereign, and demanded that the new vizier should be put to death.
Avicenna, however, remained hidden for forty days in a sheik's house, till a fresh attack of illness induced the amir to restore him to his post.

In the years1872-1878the Afghan Jamal ud-Din, a professor in the Azhar mosque at Cairo, attempted to read Avicenna with his scholars, and to exercise them in things that went beyond theology, bringing, for example, a globe into the mosque to explain the form of the earth.
A great part of his writings, particularly on jurisprudence and astronomy, as well as essays on special logical subjects, prolegomena to philosophy, criticisms on Avicenna and Alfarabius (Farabi),remain in manuscript in the Escorial and other libraries.
The larger commentary was an innovation of Averroes; for Avicenna, copied by Albertus Magnus, gave under the rubrics furnished by Aristotle works in which, though the materials.

Unquestionably the most illustrious name amongst the Oriental Moslems was Avicenna (980-1037).
In logic Avicenna starts from distinguishing between the isolated concept and the judgment or assertion; from which two primitive elements of knowledge there is artificially generated a complete and scientific knowledge by the two processes of definition and syllogism.
The place of Avicenna amongst Moslem philosophers is seen in the fact that Shahrastani takes him as the type of all, and that Ghazali's attack against philosophy is in reality almost entirely directed against Avicenna.
