The Zij (Astronomical and chronological tables) of Ulugh Beg is a
monument to the last great flowering of astronomy in the Islamic
world. Ulugh Beg (1393-1449 CE), the grandson of Tamerlane, built a
famous observatory at Samarkand which has been described as the
main centre of astronomical research in the world in its time. On
the basis of their observations at Samarkand, Ulugh Beg and his
collaborators compiled the Zij, of which this manuscript contains
the second revised edition.
