Events Occured in Scienctist Life

1092

Su Song's treatise about the clock tower, Xinyi Xiangfayao (新儀象法要), has survived since its written form in 1092 and official printed publication in 1094.

1086

After serving in the Ministry of Personnel, he became a Minister of Justice in 1086.

1063

He was appointed as a distinguished editor for the Academy of Scholarly Worthies, where in 1063 he edited, redacted, commented on, and added a preface for the classic work Huainanzi of the Han Dynasty (202 BC–220 AD).

1077

In 1077, he was dispatched on a diplomatic mission to the Liao Dynasty of the Khitan people to the north, sharing ideas about calendrical science, as the Liao state had created its own calendar in 994 AD.

1081

In 1081, the court instructed Su Song to compile into a book the diplomatic history of Song-Liao relations, an elaborate task that, once complete, filled 200 volumes.

1070

In 1070, Su Song and a team of scholars compiled and edited the Bencao Tujing ('Illustrated Pharmacopoeia', original source material from 1058–1061), which was a groundbreaking treatise on pharmaceutical botany, zoology, and mineralogy.

1088

Su Song's greatest project was the 40-foot-tall water-powered astronomical clock tower constructed in Kaifeng, the wooden pilot model completed in 1088, the bronze components cast by 1090, while the wholly finished work was completed by 1094 during the reign of Emperor Zhezong of Song.

1086

The emperor ordered in 1086 for Su to reconstruct the hun yi, or "armillary clock", for a new clock tower in the capital city.

1127

Years after Su's death, the capital city of Kaifeng was besieged and captured in 1127 by the Jurchens of the Manchuria-based Jin Dynasty during the Jin–Song wars.

1092

When Su Song's Xinyi Xiangfayao was written in 1092 and the horological monograph finalized and presented in 1094, his work was published and widely printed in the north (see woodblock printing and movable type of Bi Sheng).

1956

In 1956, John Christiansen reconstructed a model of Su Song's clocktower in a famous drawing, which garnered attention in the West towards 11th-century Chinese engineering.

1950

In China, the clocktower was reconstructed to one-fifth its actual scale by Wang Zhenduo, who worked for the Chinese Historical Museum in Beijing in the 1950s.
