OMAR KHAYYÁM, or Chiam, was born about the middle of the 11th Century, at Naishápúr, Khorassán, and he died in that town about the year 1123.Little is known as to the details of his life, and such facts as are available have been drawn principally from the Wasíyat or Testament of Mizam al Mulk (Regulation of the Realm), who was a fellow-pupil of Omar at the school of the celebrated Imám Mowafek or Mowaffak. Reference to this is made in Mirkhond's History of the Assassins, from which the following extract[A] is taken."'One of the greatest of the wise men of Khorassán was the Imán Mowaffak of Naishápúr, a man highly honoured and reverenced,-may God rejoice his soul; his illustrious years exceeded eighty-five, and it was the universal belief that every boy who read the Koran, or studied the traditions in his presence, would assuredly attain to honour and happiness. For this cause did my father send me from Tús to Naishápúr with Abd-u-samad, the doctor of law, that I might employ myself in study and learning under the guidance of that illustrious teacher.
