The Rubáyát of Omar Khayyám: (or, Rubaiyat of Omar Khayyam)

Kayyam, a Turkish astrologist, calculated the calendar and showed the earth is round and provided measurements. He lived under the Seljuk empire and support. Since many authors write in Persian, people claim many Turk as Persian due to a lack of historical knowledge.It would be best to learn the political and historical values of the time. Omar Khayyam lived in the same era and worked with Ibni Sina, Gazali, Buruni, Celaleddin Rumi’s father, and Rumi Mevlana are all great scholars. Back then, Karahanlı, Gazneli, büyük Selçuklu, Anadolu Selçuklu, Safavi, Babür empire, Özbek, and Uygur affected the era culturally like the Taj Mahal built by the Turkish sultan for the memory of his passing wife in India. Truth is hiding Turkish thinkers and calling them Persian, Arab, etc., must be corrected. Just like Jenner stole the vaccine from the Turks. Also, no one talks about Abdulhamid II who was the Ottoman Empire financed and let Turkish doctors with Pastor while nobody believed him. As a result, new vaccines developed this was another Transfer of technology from the Turks.
