Mazu — Grandmother — is unique among the great deities in having an undisputed historical origin: Lin Mo-niang, born around 960 on Meizhou Island off the Fujian coast, renowned as a woman who could read the winds, drowned in 987 trying to save her shipwrecked family. Within generations her island shrine became the patronage cult of the Chinese seas.
The imperial court enfeoffed her again and again — the Song Hui Yao records the first title, Lady Shunji, in 1123; under the Yuan, when the empire lived on coastal grain transport, she was raised to Tianfei, Heavenly Consort; the Qing made her Tianhou, Empress of Heaven. The Tianfei Lingying records collect her manifestations — always the same: red robes above the waves, a lamp in the storm.
