"Rubaiyat of Omar Khayyam" is a collection of four-line stanzas, or quatrains, translated from Persian poetry. The poems, filled with contemplations on mortality and the transient nature of life, advocate for living in the moment and enjoying life's simple pleasures. The work is revered for its beautiful and evocative imagery, philosophical musings, and its exploration of themes such as love, faith, doubt, and the fleeting nature of time.
