Arabic translation of ancient texts peaked between 750 and 900 AD
Evidence
Protected and facilitated by the expansion of Islamic states, Arabic scholars between the seventh and tenth centuries achieved access to the works of their Mediterranean predecessors. The most intensive period of translation into the Arabic from Greek, Sanskrit, Persian, and Syriac took place between 750 and 900 A.D. Translations, however, appear to have been selective, since historical works were generally neglected during the earliest period of absorption. — Cedric J.
