Rubáiyát of Omar Khayyám is the title that Edward FitzGerald gave to his 1859 translation from Farsi to English of a selection of quatrains (rubāʿiyāt) attributed to Omar Khayyam (1048–1131), dubbed "the Astronomer-Poet of Persia". The authenticity of the poetry attributed to Omar Khayyam is highly uncertain. Omar was famous during his lifetime not as a poet but as an astronomer and mathematician. The earliest reference to his having written poetry is found in his biography by al-Isfahani, written 43 years after his death.
