Mausoleum of Omar Khayyam

The Mausoleum of Omar Khayyam is a modern monument of white marble erected over Omar Khayyam's tomb located in Nishapur. Omar Khayyam  was a Persian mathematician, astronomer, and poet.

As a mathematician, he is most notable for his work on the classification and solution of cubic equations, where he provided geometric solutions by the intersection of conics. As an astronomer, he composed a calendar which proved to be a more accurate computation of time than that proposed five centuries later by Pope Gregory XIII.

Omar Khayyam died on 4 December 1131. The earliest account of Omar's final resting place is provided by his pupil Nizami Aruzi who visited his tomb in 1135-6. In Balkh, in 1112-13, Nizami heard Omar make a prophecy about his place of burial, that his grave "would be where flowers in the springtime would shed their petals over his dust".
