               Alongside the Greek influence, Arabic-speaking philosophers also had close contact with Persian and Indian thought, particularly concerning medicine, astronomy and politics, both through translations and through contacts that had already existed since the 8th century AD. One of the first works translated into Arabic was the Siddhanta – an Indian astronomical treatise that played an important role in the development of astronomy among the Arabs. Indian literature was also well received. In the 8th century AD, a work called Religious Beliefs of the Indians was already in circulation, in addition to other works of a moral and religious nature.
