Omar Khayyam was born at Naishapur in Khorassan in the latter half of our Eleventh, and died within the First Quarter of our Twelfth Century. The Slender Story of his Life is curiously twined about that of two other very considerable Figures in their Time and Country: one of whom tells the Story of all Three. This was Nizam ul Mulk, Vizier to Alp Arslan the Son, and Malik Shah the Grandson, of Toghrul Beg the Tartar, who had wrested Persia from the feeble Successor of Mahmud the Great, and founded that Seljukian Dynasty which finally roused Europe into the Crusades. This Nizam ul Mulk, in his Wasiyat--or Testament--which he wrote and left as a Memorial for future Statesmen--relates the following, as quoted in the Calcutta Review, No. 59, from Mirkhond's History of the Assassins.

"'One of the greatest of the wise men of Khorassan was the Imam Mowaffak of Naishapur, a man highly honored 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 honor and happiness. For this cause did my father send me from Tus to Naishapur with Abd-us-samad, the doctor of law, that I might employ myself in study and learning under the guidance of that illustrious teacher. Towards me he ever turned an eye of favor and kindness, and as his pupil I felt for him extreme affection and devotion, so that I passed four years in his service. When I first came there, I found two other pupils of mine own age newly arrived, Hakim Omar Khayyam, and the ill-fated Ben Sabbah. Both were endowed with sharpness of wit and the highest natural powers; and we three formed a close friendship together. When the Imam rose from his lectures, they used to join me, and we repeated to each other the lessons we had heard. Now Omar was a native of Naishapur, while Hasan Ben Sabbah's father was one Ali, a man of austere life and practise, but heretical in his creed and doctrine. One day Hasan said to me and to Khayyam, "It is a universal belief that the pupils of the Imam Mowaffak will attain to fortune. Now, even if we all do not attain thereto, without doubt one of us will; what then shall be our mutual pledge and bond?" We answered, "Be it what you please." "Well," he said, "let us make a vow, that to whomsoever this fortune falls, he shall share it equally with the rest, and reserve no pre-eminence for himself." "Be it so," we both replied, and on those terms we mutually pledged our words. Years rolled on, and I went from Khorassan to Transoxiana, and wandered to Ghazni and Cabul; and when I returned, I was invested with office, and rose to be administrator of affairs during the Sultanate of Sultan Alp Arslan.'
