A thousand years has past since the earliest days of Persian literature, a period during which Iran has gone through many ups and downs marking its tumultuous history. The children of this land, during the span of several centuries and throughout the vast areas of its dominion, have gained a vast store of experiences and made numerous achievements in various fields of knowledge. a fact that has made the fruits of the efforts of Muslims, especially Iranian Muslims, the focus of world attention. Persian literature is the true repository and the locus of manifestation of the thousand-year efforts of Persian-speaking Muslims in the field of science and arts and letters, from epic and poetry to novel and history, and from Quranic exegesis and ethics to philosophy and mysticism. In fact, Persian literature, in terms of the range of its subjects and multiplicity of its literary styles, is like unto a vast river whose limpid water sates the thirst of anyone from whatever taste or orientation; a fact whose roots must be sought in the pristine impulses of this culture.
