Hedayat subsequently devoted his whole life to studying Western literature and to learning and investigating Iranian history and folklore. The works of Rainer Maria Rilke, Edgar Allan Poe, Franz Kafka, Anton Chekhov and Guy de Maupassant intrigued him the most. During his short literary life span, Hedayat published a substantial number of short stories and novelettes, two historical dramas, a play, a travelogue, and a collection of satirical parodies and sketches. His writings also include numerous literary criticisms, studies in Persian folklore, and many translations from Middle Persian and French. He is credited with having brought Persian language and literature into the mainstream of international contemporary writing. There is no doubt that Hedayat was the most modern of all modern writers in Iran. Yet, for Hedayat, modernity was not just a question of scientific rationality or a pure imitation of European values.
