Avicenna himself was at this season stricken down by a severe illness.
Finally, at Jorjan, near the Caspian, he met with a friend, who bought near his own house a dwelling in which Avicenna lectured on logic and astronomy.
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.
On the death of the amir Avicenna ceased to be vizier, and hid himself in the house of an apothecary, where, with intense assiduity, he continued the composition of his works.
But amid his restless study Avicenna never forgot his love of enjoyment.
His bouts of pleasure gradually weakened his constitution; a severe colic, which seized him on the march of the army against Hamadan, was checked by remedies so violent that Avicenna could scarcely stand.
It was mainly accident which determined that from the 12th to the 17th century Avicenna should be the guide of medical study in European universities, and eclipse the names of Rhazes, Ali ibn al-Abbas and Avenzoar.
The best-known amongst them, and that to which Avicenna owed his European reputation, is the Canon of Medicine; an Arabic edition of it appeared at Rome in 1593 and a Hebrew version at Naples in 1491.
Scarcely any member of the Arabian circle of the sciences, including theology, philology, mathematics, astronomy, physics and music, was left untouched by the treatises of Avicenna, many of which probably varied little, except in being commissioned by a different patron and having a different form or extent.
The Aristotelian school in Islam did not speak with one voice upon the question; Avicenna declared the soul immortal, but Averroes assumes only the eternity of the universal intellect.
About 1180), in philosophy an Aristotelian (through Avicenna) and the precursor of Maimonides, is chiefly known for his Sepher haqabbalah, written as a polemic against Karaism, but valuable for the history of tradition.
His son Moses, who died about the end of the 13th century, translated the rest of Maimonides, much of Averroes, the lesser Canon of Avicenna, Euclid's Elements (from the Arabic version), Ibn al-Jazzar's Viaticum, medical works of IIunain ben Isaac (Johannitius) and Razi (Rhazes), besides works of less-known Arabic authors.
This anonymous writer,' he says, acquired his learning by teaching others, and adopted a dogmatic tone, which has caused him to be received at Paris with applause as the equal of Aristotle, Avicenna, or Averroes.
The chief of these, at least so far as regards the influence which they exerted on medieval philosophy, were Avicenna, Avempace and Averroes.
Avicenna has always been regarded as the chief representative of Arabian medicine.
His chief work, Al-Teysir (facilitatio), is thought to show more practical experience than the writings of Avicenna, and to be less based upon dialectical subtleties.
Gerard of Cremona, a physician of Toledo (1114-1187), made translations, it is said by command of Barbarossa, from Avicenna and others.
The medical literature of this period is extremely voluminous, but essentially second-hand, consisting mainly of commentaries on Hippocrates, Galen, Avicenna and others, or of compilations and compendia still less original than commentaries.
He began his lectures at Basel by burning the books of Avicenna and others; he afterwards boasted of having read no books for ten years; he protested that his shoe-buckles were more learned than Galen and Avicenna.
ABUTILON (from the Arabic aubutilun, a name given by Avicenna to this or an allied genus), in botany, a genus of plants, natural order Malvaceae (Mallows), containing about eighty species, and widely distributed in the tropics.
Unfortunately the success of Avicenna seems to have led to the neglect of much of his work.
Avicenna also makes some acute physiognomical remarks in his De animalibus, which was translated by Michael Scot about 1270.
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.
This writer undertook the task of interpreting to the Latin world some of the best work of Arabic physicians, and his translation of Avicenna is said to have been made by order of the emperor Frederic II.
In the eastern provinces the chief names of Arabian philosophy are those known to the Latin schoolmen as Alkindius, Alfarabius, Avicenna and Algazel, or under forms resembling these.
His paraphrases of Aristotle formed the basis on which Avicenna constructed his system, and his logical treatises produced a permanent effect on the logic of the Latin scholars.
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.
The stages of this process to the acquisition of mind are generally enumerated by Avicenna as four; in this part he follows not Aristotle, but the Greek commentator.
In several points Avicenna endeavoured to give a rationale of theological dogmas, particularly of prophetic rule, of miracles, divine providence and immortality.
Thus Avicenna, like his predecessors, tried to harmonize the abstract forms of philosphy with the religious faith of his nation.
Bacon, placing him beside Aristotle and Avicenna, recommends the study of Arabic as the only way of getting the knowledge which bad versions made almost hopeless.
It was not till about the middle of the 12th century that under the patronage of Raymond, archbishop of Toledo, a society of translators, with the archdeacon Dominicus Gundisalvi at their head, produced Latin versions of the Commentaries of Avicenna, and Ghazali, of the Fons Vitae of Avicebron, and of several Aristotelian treatises.
