The prophet Muhammad and the early Islamic community radically redefined the concept of time that they had inherited from earlier religions' beliefs and practices. This new temporal system, based on a lunar calendar and era, was complex and required sophistication and accuracy. From the ninth to the sixteenth centuries, it was the Muslim astronomers of the Ottoman, Safavid and Mughal empires who were responsible for the major advances in mathematics, astronomy and astrology. This fascinating study compares the Islamic concept of time, and its historical and cultural significance, across these three great empires. Each empire, while mindful of earlier models, created a new temporal system, fashioning a new solar calendar and era and a new round of rituals and ceremonies from the cultural resources at hand. This book contributes to our understanding of the Muslim temporal system and our appreciation of the influence of Islamic science on the Western world.

The main reference source for questions of Islamic philosophy, science, and technology amongst Western engaged readers and academics in general and legal researchers in particular.

Omar Khayyam was born at Naishapur in Khorassan in the latter half of our Eleventh, and died within the First Quarter of our Twelfth Century. The Slender Story of his Life is curiously twined about that of two other very considerable Figures in their Time and Country: one of whom tells the Story of all Three. This was Nizam ul Mulk, Vizier to Alp Arslan the Son, and Malik Shah the Grandson, of Toghrul Beg the Tartar, who had wrested Persia from the feeble Successor of Mahmud the Great, and founded that Seljukian Dynasty which finally roused Europe into the Crusades.

A repository of subversive, melancholic and existentialist themes and ideas, the rubaiyat (quatrains) that make up the collected poems attributed to the 12th century Persian astronomer Omar Khayyam have enchanted readers for centuries. In this modern translation, complete with critical introduction and epilogue, Juan Cole elegantly renders the verse for contemporary readers. Exploring such universal questions as the meaning of life, fate and how to live a good life in the face of human mortality, this translation reveals anew why this singular collection of poems has struck a chord with such a temporally and culturally diverse audience, from the wine houses of medieval Iran to the poets of Western twentieth century modernism.
