Biography

Born in the town of Xi'e in Nanyang Commandery (located north of modern Nanyang City, Henan province), Zhang Heng came from a distinguished but not very affluent family. His grandfather, Zhang Kan, had been governor of a commandery, and one of the leaders who supported the restoration of the Han Dynasty by Emperor Guangwu (r. 25–57), following the death of the usurper Wang Mang and his short-lived Xin Dynasty (AD 9–23). At age ten, Zhang's father died, leaving him in the care of his mother and grandmother. An accomplished writer in his youth, Zhang left home in 95 to pursue his studies in the ancient capitals of Chang'an and Luoyang. While traveling to Luoyang, Zhang passed by a hot spring near Mount Li and dedicated one of his earliest fu poems to it, the Wenquan (溫泉). After studying for some years at Luoyang's (Taixue), he became well-versed in the classics, and befriended notable persons, such as the mathematician and calligrapher Cui Yuan (78–143), the official and philosophical commentator Ma Rong (79–166), and the philosopher Wang Fu (78–163). Government authorities offered Zhang appointments to several offices, including a position as one of the Three Excellencies, yet he acted modestly and turned down those positions. At age twenty-three, he returned home with the title "Officer of Merit in Nanyang," serving as the master of documents under the administration of Governor Bao De (in office from 103–111). As he was charged with composing inscriptions and dirges for Bao De, he gained experience in writing official documents. As Officer of Merit in the commandery, he was also responsible for local appointments to office and recommendations to the capital of nominees for higher office. He spent much of his time composing rhapsodies on the capital cities. When Bao De was recalled to the capital in 111, to serve as a minister of finance, Zhang continued his literary work at home in Xi'e. Zhang Heng began his studies in astronomy at the age of thirty, and began publishing his works in astronomy and mathematics.X
