Scholars have argued that in the late nineteenth century, maps became important vehicles in anticipating national space in East and Southeast Asia. (Anderson, Winichakul) While Qing and Tokugawa mapping practices from earlier centuries have been studied, little work exists on how mapping relates to ethnogenesis, printing and conceptions of space among the maritime Hokkien and Cantonese. Three early eighteenth-century maps depicting the maritime frontier reveal differing conceptions of relations with coastal environments. First, a coastal map produced by Matteo Ripa while working on the Kangxi emperor’s imperial map in the 1710’s precisely details coastal islands from Hainan to Sakhalin as a coherent but limited space of maritime engagement. Pioneered by some Ming maps (Zhang Huang), this strategy was adopted by the Qing especially from the 1730’s (Chen Lunjiong). Second, a 1710’s map by the Fujianese military commander Shi Shibiao shows trading routes from Fujian to Southeast Asia and Japan. Similarities to the Min-language Selden Map (ca. 1619, Bodleian) as well as Japanese maps suggest complex cultural influences. Finally, a large eighteenth-century printed sheet map of Guangdong offers an integrated image of the relationship between village organization and local and regional maritime trade. Similar strategies appear on an early-Qing manuscript scroll map of Taiwan. Interactions among printed and manuscript maps offer insight into emerging ethnic and maritime identities, challenging monolithic imperial or civilizational accounts of Qing approaches to maritime and littoral space.
