The Crow Terrace poetry case
In 1079 officials of the Censorate combed Su Shi’s poems and prose, pinning "mockery of the court" on line after line, and arrested him from his post at Huzhou and hauled him to the capital, into the Censorate (the "Crow Terrace") prison for a hundred and thirty days, where he once thought death certain and arranged with his son that a gift of fish would be the secret signal of it. The Grand Empress Dowager pleaded for him from her sickbed, and the retired Wang Anshi memorialized, "How can a sage age put a talented scholar to death?" Shenzong in the end did not kill him, demoting him to deputy military trainer of Huangzhou. It is one of the most famous literary inquisitions in Chinese history — and an extreme test of the Song’s bottom line of "not killing scholar-officials."
