His nisbah designates him as a native of Ganja (Elizavetpol, Kirovabad) in Azerbaijan, then still a country with an Iranian population, and he spent the whole of his life in Transcaucasia; the verse in some of his poetic works which makes him a native of the hinterland of Qom is a spurious interpolation."

How is it that a Persian boy born almost eight hundred years ago in Khorasan, the northeastern province of greater Iran, in a region that we identify today as Central Asia, but was considered in those days as part of the Greater Persian cultural sphere, wound up in Central Anatolia on the receding edge of the Byzantine cultural sphere, in which is now Turkey, some 1500 miles to the west?
