The term "rubaiyat" refers to a form of Persian poetry consisting of quatrains, or four-line stanzas. Each stanza typically follows a rhyme scheme of AABA. This poetic style is often associated with the works of the 11th-century poet Omar Khayyam, whose collection of quatrains gained widespread popularity in the West through translations. The most famous translation of the Rubaiyat of Omar Khayyam was done by Edward FitzGerald in the 19th century. This version helped introduce the beauty of Persian poetry to English-speaking audiences, emphasizing themes of love, nature, and the fleeting nature of life.
