About Omar Khayyam of Persia, the poet and mathematician, who wrote the Iranian first solar calendar circa A.D. 1073. His fiancé was forced to marry the shah, but she eventually escaped and, with help of grand Vazir, joined Omar Khayyam. Hollywood made a film based on the same story with Connell Wilde, the life and adventures of Omar Khayyam.
