<em>Omar Khayyam is widely recognized as the famous Persian poet, mathematician, and astronomer. His poems were written in 'Farsi' and translated later into English by Fitzgerald. His most famous works of poetry translated by Fitzgerald include "The Rubaiyat"(his compilation of hundred quatrains(rubais)) that celebrates the bliss of life while lighting up the political and religious ambiance of the time yet counters the dogmas of Islam which made him squabble of court patrons.</em> His work as a poet, astronomer, and mathematician is still considered significant due to its lively impact and celebration of pleasures of life.
