Sailors in premodern China performed various types of rituals to pray for safe voyages. This article investigates a unique seven-dot image discovered from shipwrecks dated to thirteenth- and fourteenth-century China. Comparing the seven-dot image with the Big-Dipper image in premodern navigation maps, this article demonstrates that the seven-dot image represents the Big Dipper. The Big Dipper in premodern China was both an essential, practical guidance in maritime voyages and a religious symbol that the faithful believed could prolong the human’s lifespan and command the element of water. The dual function of the Big Dipper endowed the Big-Dipper images in ships with a dual meaning and made it particularly auspicious. The Big Dipper’s practical function prompted the carvers to present the image accurately, making it distinctive from other Big-Dipper images in the religious context.
