Note 415 — Chapter XXV · The Successors of Tīmūr
Reading edition
His astronomical tables are amongst the most accurate and complete that come down to us from Eastern sources. They treat of the measurement of time, the course of the planets, and of the position of fixed stars. The best editions are those printed in Latin in 1642–48 by an Oxford professor named Greaves, and reprinted in 1767. The remains of his celebrated observatory still crown the hill known as Chupān Ata in an eastern suburb of Samarkand.
