About the Life of Ghija ud-din Abu'l Fath Umar Ibn Ibrahim Ul-Khayyami, as he is called in the oldest Arabic sources, is little secured. He was considered a great mathematician and astronomer who became famous through scientific treatises in the Arabic language, but above all through the creation of a calendar that is in some ways even superior to the Gregorian. This was officially introduced in 1079, replacing the Arab-Islamic lunar year with the Persian solar year. In Europe he became known as Omar Khayyam through his approximately 750 quatrains (Rubaiyat). He was born between 1021 and 1048 in Nishapur, then the largest city in ancient Persia ( Iran ). Here he spent the vast majority of his life and was there between 1122 and 1131 died and buried.
His partially pessimistic drinking songs were directed against religious fanaticism and heretical against the Islamic alcohol ban : "I do not know if the one who designed my nature has prepared me a home in heaven or in the terrible hell. But a little food, an adored one and some wine on a green heap - that's wealth - keep for you the heaven that you trust so well . " Another example: "Every day I take it upon myself anew that I leave drinking and repent; but since rose scent appeared the fair Lenz - I regret my regret " . Omar Khayyam also wrote about the legendary king Jamshid, at whose farm, according to legend, the wine was invented. Another famous Persian poet is Hafiz (1324-1390).
