Abstract

Avicenna or Ibn Sīnā was born circa 980 in Afshna, near Bukhara, in Persia. He worked briefly for the Samanid administration, but left Bukhara, and lived in the area of Tehran and Isfahan, where he completed the Shifā under the patronage of the Daylamite ruler, ‘Ala’-al Dawla, and wrote his most important Persian work, the Dānish-nāma, which contains works on logic, metaphysics, physics, and mathematics
