World Map Showing Hemispheres
A beautiful and impressive historical map of the world drawn by Jean Janvier in 1775 depicts the entire world on a double hemisphere projection. In the map, North America appears with a fair approximation of accuracy through the western and northwestern regions remain either blank or entirely speculative. Alaska is entirely absent, but the Aleutian archipelago does appear in an embryonic form. By contrast, the northeast parts of Asia, which had recently been explored by Vitus Bering and Tschirikow, are depicted with a fair approximation of accuracy. Both the apocryphal Terre de Gama and Terre de la Company appear just northeast of Yedso (Hokkaido). Often called de Gamma Land or Gama, these islands were supposedly discovered in the 17th century by a mysterious figure known as Jean de Gama.
Various subsequent navigators claim to have seen this land, but it was left to Bering to finally debunk the myth. South of the equator the shores of Australia or New Holland are speculatively mapped with a dotted line defining the southern edge of the continent. Van Diemen's Land or Tasmania is depicted attached to the mainland. Polynesia is mapped with numerous islands named, but few are the correct size or in the correct place. Hawaii, which had not yet been discovered by Cook, is entirely absent. In South America, many of the speculative geographic elements common to earlier maps of the regions, such as El Dorado and Lake Parima, are absent through the Lago de Xarayes does remain. Africa, as usual, is mapped accurately along the coasts and speculatively in the interior. While numerous tribes, kingdoms, and desert caravan routes are noted, most of the interior is conjectural. The Nile follows the two lake pattern developed in the 15th century on Ptolemaic maps. The gold mining region near the Kingdom of Monomotapa is labeled. South Africa is noted as the home of the Cafrerie and Hottentots. The great southern content, a kind of speculative proto-Antarctica common to many early maps, is entirely absent, though several Antarctic islands, including the Cap de la Circoncision (Bouvet's Island) and Lozier's B. de L'Oiseau, are noted. Both hemispheres are crowned with an elaborate decorative cartouche in the late baroque style. Drawn by Janvier as plate no. 1 in volume 1 of Jean Lattre's 1775 Atlas Moderne .
