When in 1949—52 the three anthologies of Omar Khayyam dated 604/1208, 613/1216 and 658/1259 appeared in quick succession in the West it was quite natural to hail them as our guides for establishing the much discussed poetical heritage of Khayyam.

Up to a decade ago, Omar was regarded by scholars as a comparatively minor Persian poet. But within the past three years this view has been shown to be entirely wrong. Two new manuscripts of Omar’s poetry have been found, and one of them dated only 85 years after Omar’s death. From these Professor Arberry, of the University of Cambridge, has discovered that Omar was regarded by Persians as one of their greatest poets, and that the existing quotations point to an original corpus of at least 750 quatrains.
