Ibn Sina was born in 980 C.E. in the village of Afshana near Bukhara which today is located in the far south of Russia. His father, Abdullah, an adherent of the Ismaili sect, was from Balkh and his mother from a village near Bukhara.
In any age Ibn Sina, known in the West as Avicenna, would have been a giant among giants. He displayed exceptional intellectual prowess as a child and at the age of ten was already proficient in the Qur'an and the Arabic classics.

He entered the services of Ali ibn Ma'mun, the ruler of Khiva, for a while, but ultimately fled to avoid being kidnapped by the Sultan Mahmud of Ghazna. After many wanderings he came to Jurjan, near the Caspian Sea, attracted by the fame of its ruler, Qabus, as a patron of learning. Unfortunately Ibn Sina's arrival almost coincided with the deposition and murder of this ruler.
At Jurjan, Ibn Sina lectured on logic and astronomy and wrote the first part of the Qanun, his greatest work. He then moved to Ray, near modern Teheran and established
