Anecdotes
According to his autobiography, Ibn Sina is said to have memorized the entire Quran by the age of ten, then devoured the works of logic, mathematics, and medicine of his time. By around sixteen, he was already treating the sick and claimed to have found medicine “easy” to learn.
He recounts having struggled for months with Aristotle's *Metaphysics*, which he is said to have reread forty times without understanding it. It was by chance, coming across a short commentary by al-Farabi bought from a secondhand bookseller for a few coins, that everything suddenly became clear to him.
As a young man, he cured the Samanid emir Nuh ibn Mansur of an illness that the other physicians did not know how to treat. As a reward, he was granted access to the famous royal library of Bukhara, where he was able to read rare works that he never found anywhere else.
His life was a succession of journeys and political upheavals: he had to flee several courts, was even imprisoned in the fortress of Fardajan, and he often wrote at night, after his days of service to the princes. It is said that he dictated certain chapters from memory to his students.
The *Canon of Medicine* (al-Qanun) that he composed became a reference textbook taught in the universities of Europe and the Muslim world alike for nearly six centuries, translated into Latin under the name Avicenna.
