The engraving presents two geometric fortifications in precise measured outline, drawn at a scale of 20 toises per division, with a note explaining that 20 leagues equal one degree of latitude, corresponding to 5,000 toises. The star-shaped bastion layout, with angled walls and projecting defensive points, reflects European military architecture of the 17th century, introduced to Asia during the Dutch colonial period. This fort is almost certainly Fort Zeelandia in Tainan, built by the Dutch East India Company between 1624 and 1634. The stronghold was a key base for Dutch trade and military operations in the region until 1662, when it was surrendered to Chinese forces led by Koxinga (Zheng Chenggong). Its depiction here reflects both historical interest and the Jesuit mission to accurately document geographic and architectural features of strategic sites. The clean, uncluttered linework and precise proportions are typical of Enlightenment-era French surveying engravings, intended for both scientific accuracy and publication in missionary or travel accounts.
