VIRGINIA POSTREL: Recovering China’s Past on Kenya’s Coast. “The underwater search for shipwrecks follows a dig last summer in the village of Mambrui that unearthed a rare coin carried only by emissaries of the Chinese emperor, as well as a large fragment of a green-glazed porcelain bowl whose fine workmanship befits an imperial envoy.
