Lampacau

The exact location of Lampacau has been a somewhat of a puzzle to the students of the region's historical geography, since both the coastlines and the place names in the area have changed significantly since the 16th century. The Portuguese maps of the period showed it located somewhat west of Macau, but closer to that city than Shangchuan ('''', "St John's Island") farther to the southwest. According to the research of Chang Tseng-hsin, making use of both Chinese and Western sources, Lampacau has become connected with the neighboring island of Lianwan (). The name of Lianwan was thus used for the entire "new" greater island, and the name Langbaiao became relegated to the narrow straight separating Lianwan from the nearby Wenwan Island (). This would place Lampacau within the Jinwan District of present-day Zhuhai, some west of Macao and much closer than that to Zhuhai Sanzao Airport. ==Name==

Over the last 100 years, there has been a lively debate of what the "proper" name of the island was during its heyday. The most recent survey of the literature on that topic is probably the page-long note in Witek & al. It lists the following spelling variants as attested in European sources, mostly Portuguese: Lampacau, Lampacam, Lam Puk, Lanpacan, Lampachan, Lampchào, Lamapacào, Lamapzan, Lanpetan, Lampaço; Lan-pai-kao (in Mandarin) and Long-pa-kao (in Cantonese); Langpetsao. They note that the character notionally is a Cantonese character and does not often appear in standard Chinese dictionaries; it is thus only natural that the name of the place would be written differently in most Chinese sources. Modern Chinese variants include Langbaiao, Langbaizao, and Lanbaijiao. ==History==

Lampacau became important for the international trade , when the center of the Portuguese offshore trade in the Pearl River Delta gradually shifted there from the more remote Shangchuan. Ptak speculates that it was a more convenient base for the transshipment of cargoes to and from sampans and other river boats traveling to the interior of Guangdong. The brief period of Lampacau's significance ended some time , as the Portuguese trade moved to the recently established permanent base, Macau. ==See also==
