Rubaiyat of Omar Khayyam by Omar Khayyam Rendered into English Verse by Edward Fitzgerald Rubaiyat of Omar Khayyam is the title that Edward FitzGerald gave to his translation of a selection of poems, originally written in Persian and numbering about a thousand, attributed to Omar Khayyam (1048-1131), a Persian poet, mathematician and astronomer. A ruba'i is a two-line stanza with two parts per line, hence the word rubayot, meaning -quatrains-. The number of quatrains attributed to Khayyam varies from about 1,200 to over 2,000. Many scholars believe that not all the attributed quatrains are authentic and some have been added to Khayyam's Diwan in later years for various reasons. A few literary researchers, for example, Mohammad-Ali Foroughi and Farzaneh Aghaeipour have selected and published a subset of the quatrains believed to be original using various research methods.
