An Evaluation of khayyam's notion on the Basis of the corpus of his Authentic Quatrains

There is no thinker like Omar Khayyam Neishaboury. Likewise, there is no poetry which invites us as much to dialogue, discussion, and translation as his Quatrains. I would belive that the study of Khayyam's notion should be based on the corpus of his authentic Quatrains. In order to distinguish the Quatrains that were written by khayyam from the derivative ones, it is necessary to separate all of them by studying all this writings and comparing those Quatrains with the authentic ideas snd believes of khayyam which we withdrew from our study on all his works. In this paper constraints are introduced for identifying khayyam's authentic Quatrains. with the aid of these parameters, Quatrains which play a key-role in khayyam's thought were selected. On the basis of these results, it was possible to re-evaluate the understanding of khayyam's thought in European and Western Studies on this subject, from his own lifetime until the present day.
