1782 Janvier Map of Africa

A fine example of Jean Janvier's 1782 map of Africa. Janvier's map covers the entire continent of Africa as well as the island of Madagascar and adjacent parts of europe, Arabia, and Persia. Like most 18th century maps of Africa, the present example is rife with speculation regarding the largely unexplored interior.

What little was known of Africa, however, Janvier incorporates here in an impressive compilation of the most up to date reports from colonial, missionary, and exploratory entradas into the interior of the continent. Thus well mapped parts of the continent are limited to the Mediterranean Coast, Morocco, the Senegambia, the Congo, South Africa, the Kingdom of Monomatapa, Abyssinia, and egypt. Morocco, egypt, and the southern Mediterranean Coast (Barbary) were well known to europeans since antiquity and Janvier's accurate mapping of these regions reflects continual contact. Further south the colonial enclaves along the Niger River (Senegal and Gambia), the Congo River, and South Africa reflect considerable detail associated with european penetration by traders and missionaries. The land of Monomopota around the Zambezi River was explored early in the 16th century by the Portuguese in hopes that the legendary gold mines supposedly found there would counterbalance the wealth flowing into Spain from the New Word. Unfortunately these mines, often associated with the Biblical kingdom of Ophir, were mostly tapped out by the 15th century. Abyssinia (modern day ethiopia) was mapped in detail by early Italian missionaries and of considerable interest to europeans first, because it was (and is) predominantly Christian; second, because it was a powerful well-organized and unified kingdom; and third because the sources of the Blue Nile were to be found here.

The remainder of the continent remained largely speculative though Janvier rarely lets his imagination get the upper hand. He does however follow the well-established Ptolemaic model laid down in the Geographica regarding the sources of the White Nile – here seen as two lakes at the base of the semi-apocryphal Mountains of the Moon. However, he also presents a curious network of interconnected rivers extending westward from the confused course of the White Nile following the popular 18th century speculation that the Nile may be connected to the Niger. To his credit Janvier does not advocate this and offers no true commerce between the two river systems.

Lake Malawi, here identified as Maffi, appears in a long thin embryonic state that, though it had not yet been 'discovered,' is remarkably accurate to form. Lake Malawi was not officially discovered until Portuguese trader Candido Jose da Costa Cardoso stumbled upon it in 1849 – almost one hundred years following Janvier's presentation of the lake here. Janvier 's inclusion of Lake Malawi is most likely a prescient interpretation of indigenous reports brought to europe by 17th century Portuguese traders. Its form would be followed by subsequent cartographers well into the mid-19th century when the explorations of John Hanning Speke, David Livingstone, Richard Francis Burton and others would at last yield a detailed study of Africa's interior.
