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.
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.
According to the great Avicenna and Maimonides, faith and the highest reason are sure to coincide (see Arabian Philosophy).
But amid his restless study Avicenna never forgot his love of enjoyment.
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.
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.
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.
When the library was destroyed by fire not long after, the enemies of Avicenna accused him of burning it, in order for ever to conceal the sources of his knowledge.
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.
When the storm had passed Avicenna returned with the amir to Hamadan, and carried on his literary labours; but at length, accompanied by his brother, a favourite pupil, and two slaves, made his escape out of the city in the dress of a Sufite ascetic. After a perilous journey they reached Isfahan, and received an honourable welcome from the prince.
