Excerpt from Umar Khayyam and His Age The writer is indebted to many books for his facts and the conclusions he has based on the facts. All of them cannot be mentioned here. But he must mention with particular gratitude - ih addi tion to Professor Browne's standard work on Persian literature - the Recherches sur les Rubai yat written by A. Christensen and published in 1905 Ignacz Goldziher's excellent study of The Influence of Parsiism on Islam published in English in 1912; Sir Edward Denison Ross's introduction to the edition of 1900; and Von Kramer's fine history of the Islamic spirit.
