This is an old topic I thought I'd present now to coincide with the recent release of the interview with the curators of "Clockwork Treasures From China's Forbidden City. Usually, I release new shows on Sundays at 5 AM L.A. Time. Since I'll be launching the first episode of Season 9 of the Chinese Sayings Podcast this Sunday, I figured I'd release this one Thursday, fresh on the heels of the interview. This is a quick and easy episode that traces the beginnings of timekeeping in China and will survey a few of the most notable horologists from Chinese history from the Han to the Qing Dynasties. The achievements of Zhang Heng, Yi Xing, Zhang Sixun, Su Song, and Zhan Xiyuan will be examined. Then we'll finish off with the arrival of the Jesuits and the zimingzhong 自鸣钟 clocks they brought with them. Thanks a bunch for listening.
