Sze Tsung Leong’s view of Nanjing makes visible the dramatic changes in the city’s central district, revealing three periods of Chinese history, layered like geological strata: the ruins of vernacular houses from the imperial period in the foreground; partially demolished collective apartment housing blocks from the Communist period in the middle ground; and new office and residential towers from the latest, capitalist period, rising on the horizon. The artist describes this erasure of the past and unfolding of a new history atop it as “the dense sedimentation of history.”
