Petrus Plancius was a Flemish-born theologian, cartographer, and cosmographer who became one of the key figures in Dutch maritime geography in Amsterdam. In the early 1590s, as Dutch merchants prepared to challenge Portuguese control of the sea route to Asia, Plancius helped turn newly acquired Iberian geographical intelligence into printed maps useful for navigation, commerce, and investment.This map shows southeastern Africa, Madagascar, and the western Indian Ocean, including the coasts of Manicongo, Angola, Monomotapa, Natal, Sofala, Mozambique, and Abyssinia. The long Latin title emphasises coasts, shoals, sandbanks, Madagascar, and the sea route through the western Indian Ocean. It is therefore not simply a regional map of Africa, but a map of the maritime approach to the East Indies.

The map is closely tied to Dutch ambitions in Asian trade. Plancius drew on Portuguese charts and rutters at a time when such knowledge was commercially and politically sensitive. The route around southern Africa, past Madagascar and Mozambique, was essential for ships sailing from Europe to the Indian Ocean and Southeast Asia. In this sense, the map forms a western Indian Ocean counterpart to Plancius’s Spice Islands map (376and 72). The decorative programme reinforces the map’s maritime purpose. Compass roses, rhumb lines, ships, sea monsters, animals, and coastal place names animate the sheet. A large Dutch ship flies the Amsterdam flag, visually claiming Dutch maritime presence in waters previously dominated by Portuguese navigation.

One of the most striking features is the vignette at lower right showing shipwrecked sailors attacked by giant lobsters. This refers to the wreck of the São Tiago or St. Jacobus on the Bassas da India, between Mozambique and Madagascar, in 1586. The story became part of Dutch maritime legend and was reused in later printed maps including Barent Langenes’s Caert-Thresoor (285) and accounts.

Within the collection, this map is closely connected with Plancius’s Insulae Moluccae celeberrimae (376and 72), which represents the eastern goal of the same maritime route. It also relates to Linschoten’s African and Indian Ocean mapping in the collection, including the maps of South and West Africa and East Africa (277and 278), and to Ortelius’s Indiae Orientalis, Insularumque Adiacientium Typus (106), where the East Indies appear within an earlier atlas framework. Together these works show how African, Indian Ocean, and Southeast Asian geography were linked by the practical demands of long-distance trade.
