A Philosopher in Travel: Ahmad b.Tayyib Sarakhsi and his diary book A study of geographical text from the 9th century

Ahmad b. Tayyib Sarakhsi, the pupil of the philosopher al Kindi, was one of the Pioneers in the Hellenistic Philosophy scholars among the Muslims. He was a well-learned scholar in the various scientific disciplines. Sarakhsi translated and extracted a great deal of Greek scientific-philosophical books and texts into Arabic language. Unfortunately none of his books are available to us. Some of his works relate to mathematical-descriptive global geography. One of them is his Diary about Djazira,al Sham and Palestine. Some portions of the Diary are scattered in the various Arabic source books. By the gathering the scattered parts some of the dairy could be reconstructed. In this manner we would have a new perception on the geography, regarding a portion of the Islamic world at the end of 9th century.
