The Rubaiyat of Omar Khayyam, like most Persian poetry, was written in the Persian language with a specific literary style and structure. Persian poetry is known for its euphony, imagery, and richness of expression. Khayyam composed the Rubaiyat using a specific form of Persian poetry called Rubai, which is a type of quatrain.
