Khayyam Neyshaburi was a famous mathematician and philosopher of the fifth century, who became a poet after his death. One of his most prominent works is arranging and supervising the Iranian solar calendar. Khayyam's calculations in this regard are still valid and far more accurate than the AD calendar. Khayyam's role in solving third-order equations and his studies of Euclid's Fifth Principle have made him a prominent mathematician in the history of science. Although Khayyam's scientific base is superior to his literary status, But his reputation is more motivated by his world-famous quatrains.
Khayyam's Tomb is Neyshabur's most magnificent tourist destination and a prominent example of modern Iranian architecture designed by Hooshang Seyhoun and completed on September 1, 1962. His design is based on Khayyam's life, time, and ideas on all three "mathematicians", "astronomers" and "poets".The structures around the tomb are approached by Khayyam's father (tentmaker); he is 22 meters tall; his configuration is concrete with a metal core; in a garden on the outskirts of Neyshabur. Moreover there is a mosque that is being honored as an Imamate by Shiite Muslims.
The structure has 10 bases, which is 10, the first mathematical 2-digit number. From each base, two diagonal blades spiral upwards to cut each other to form the roof of the building and land on the other, which is one of the most complex mathematical forms. This geometric form and 10 numbers are both symbols of Omar Khayyam's mathematical knowledge.
The blades collide with each other, filling empty spaces, and especially above, to create intermittent stars, among them the blue sky of Neyshabur, and gradually nearing the dome's head, the stars become smaller and eventually complete a five-pointed star. These stars and the role of the sky refer to Khayyam's astronomical personality.
The blades collide together to form ten large lozenges
Tiles in the Nastaliq line and filled with Khayyam's quatrains by the great calligraphers like Miremad. Quatrains was chosen by Jalal Hamayi, and the beautification was done by Morteza Abdul Rasouli. In the history of Iranian architecture, this is the first building in which the Nastaliq Broken Line was used. From the inside, the same rhymes filled with poetry featuring flowers and leaves and ivy were decorated with mosaic tiles, all of which refer to Khayyam's poetry.
Hooshang Seyhoun said:
Around the Tower Beside the springs, a large circle was built at the center of the tower. All of the granite stone is triangular-shaped with indentations and extrusions that somewhat resemble the shape of a tent, and this is referred to as Khayyam. Because his father was a tentmaker and his name was chosen for the occasion . On the other hand, the pools with turquoise tiles that represent a part of the star as a whole, numbered seven in the sense of seven celestials and seven heavens and seven hills again referring to the planets And astronomy is another knowledge of Khayyam.
All in all, the complex was built in a poetic mood with bushy trees around it, completely open as Khayyam himself wished, and his flowers were in bloom.
