Ulugh Beg

Astronomy

Title assumed by Muhammad Taragi (1394–1449), Mongol ruler and astronomer, born in modern Iran. In 1420 he established an observatory at Samarkand, in modern Uzbekistan. He equipped it with a huge (radius 40 m) sextant of stone which allowed observations accurate to a few seconds of arc to be made. The result was the first original star catalogue since those of Ptolemy and al-Ṣūfī, which it surpassed in precision.

The title Ulugh Beg, assumed by Muhammad Taragi, was a grandson of Tamerlane. He was born at Soltaniyeh (now in Iran) and succeeded to the throne in 1447 but was killed by his rebellious son two years later. He began building an observatory at Samarkand in 1420. He was himself an observer and published planetary tables and a catalog of stars in 1437. They were published in Europe in 1665. The observatory was said to have had a gnomon for measuring the elevation of the Sun as high as the dome of St. Sophia in Byzantium (180 feet).
