literal interpretation. Thus, the view of Omar Khayyam as a Sufi was defended by Bjerregaard (1915). Dougan (1991) likewise says that attributing hedonism to Omar is due to the failings of FitzGerald's translation, arguing that the poetry is to be understood as "deeply esoteric". Idries Shah (1999) similarly says that FitzGerald misunderstood Omar's poetry. The Sufi interpretation is the view of a minority of scholars. Henry Beveridge states that "the Sufis have unaccountably pressed this writer [Khayyam] into their service; they explain away some of his blasphemies by forced interpretations, and others they represent as innocent freedoms and reproaches". Aminrazavi (2007) states that "Sufi interpretation of Khayyam is possible only by reading into his Rubaiyat extensively and by stretching the content to fit the classical Sufi doctrine". FitzGerald's "skepticist" reading of the poetry is still defended by modern scholars. Sadegh Hedayat (The Blind Owl, 1936) was the most notable modern proponent of Khayyam's philosophy as agnostic skepticism. In his introductory essay to his second edition of the Quatrains of the Philosopher Omar Khayyam (1922), Hedayat states that "while Khayyam believes in the transmutation and transformation of the human body, he does not believe in a separate soul; if we are lucky, our bodily particles would be used in the making of a jug of wine". He concludes that "religion has proved incapable of surmounting his inherent fears; thus Khayyam finds himself alone and insecure in a universe about which his knowledge is nil". In his later work (Khayyam's Quatrains, 1935), Hedayat further maintains that Khayyam's usage of Sufic terminology such as "wine" is literal, and that "Khayyam took refuge in wine to ward off bitterness and to blunt the cutting edge of his thoughts." Editions FitzGerald's text was published in five editions, with substantial revisions: 1st edition – 1859 [75 quatrains] 2nd edition – 1868 [110 quatrains] 3rd edition – 1872 [101 quatrains] 1878, "first American edition", reprint of the 3rd ed. 4th edition – 1879 [101 quatrains] 5th edition – 1889 [101 quatrains] Of the five editions published, four were published under the authorial control of FitzGerald. The fifth edition, which contained only minor changes from the fourth, was edited posthumously on the basis of manuscript revisions FitzGerald had left. Numerous later editions were published after 1889, notably an edition with illustrations by Willy Pogany first published in 1909 (George G. Harrap, London). It was issued in numerous revised
