In the 1100s, Omar Khayyam developed the rubaiyat, a form of quatrain poetry that explores philosophical themes such as doubt, pleasure, and fate. His quatrains reflect a deep understanding of the human condition and have resonated with readers for centuries. Khayyam's contributions to Persian literature have made him a significant figure in both poetry and philosophy.

The development of the Rubaiyat quatrain by Omar Khayyam in the 1100s popularized the AABA rhyme scheme, later translated by Edward FitzGerald. This form inspired carpe diem themes in English poetry, influencing poets like Alfred Lord Tennyson and W. B. Yeats.
