Life In Iran

During this era, Iranians continued on a much larger scale the cultural and scientific enterprises set up by the Sassanids. The blossoming Persian literature, philosophy, medicine, and art became major elements in the forming Muslim civilization. The Islamic Golden Age, which is characterized by developments in science, owed to a large extent its importance to vital contributions made by Iranians. The Islamic Golden Age reached its peak in the 10th and 11th centuries, during which Persia was the main theatre of scientific activity. The Persian influence of this period relied heavily upon the achievements of the Sassanids, and the weight of this influence has led the Muslim world to accept Islamic civilization as the Perso-Islamic civilization.
Even in the development of Arabic scientific prose itself, which differs in style from that of the Quran, Persian scholars such as Abdullah Ibn al-Muqaffaʿ had a major role. Indeed, the class of clerks and civil administrators that was responsible for the cultivation of the sciences in the early Islamic centuries consisted mostly of Persians. The contributions of Iranians to the Arabic language are however not limited to scientific prose but are also found in Arabic poetry. The contributions by Iranians are characterised as "the lively and graceful fancy, elegance of diction, depth and tenderness of feeling, and a rich store of ideas".
Iranian philosophy after the Islamic conquest is characterized by different interactions with Old Iranian philosophy, with Ancient Greek philosophy, and with the development of Islamic philosophy. Illuminationism and transcendent theosophy are regarded as two of the main philosophical traditions of this era in Persia. These movements continued well into the 11th century, during which the Nizamiyya University was founded, and hundreds of Iranian scholars and scientists contributed greatly to technology, science, and medicine, later influencing the rise of European sciences during the Renaissance.
