A fine example of Jansson's sea chart of the Pacific, the first chart of the Pacific to show California as an island and the earliest sea chart of the Pacific to appear in a Dutch Atlas.

A long chain of islands appears in the South Pacific, which are likely a vestige of Terra Australis. These were noted by Jansson to have been discovered by Hernando Gallego in 1576. The first mention of this explorer appears in a Hondius map of the Antarctic, and his existence is difficult to confirm. A journey by Juan Fernandez in search of Terra Australis in that year did claim to discover a mountainous island that some early scholars believed could be New Zealand. The earliest accepted date for European colonization of New Zealand is 1642.

California is shown as an island, based upon the Briggs model, but lacking the 2nd Punta de la Concepcion suggesting reliance upon Goos or his sources. Jansson includes a length note about the island and previous mapping. The large Terra Incognita in the Northwest nearly connects Asia with the Island of California, separated only by the Fretum [Strait] Anian.

Many places in California are named, from Cabo San Lucas to the Cabo Mendocino. Some islands of the West Pacific start to take shape, with a part of  Papua outlined. Many other islands, real and imaginary, are shown.

Jan Jansson Biography

Jan Janssonius (also known as Johann or Jan Jansson or Janszoon) (1588-1664) was a renowned geographer and publisher of the seventeenth century, when the Dutch dominated map publishing in Europe. Born in Arnhem, Jan was first exposed to the trade via his father, who was also a bookseller and publisher. In 1612, Jan married the daughter of Jodocus Hondius, who was also a prominent mapmaker and seller. Jonssonius’ first maps date from 1616.

In the 1630s, Janssonius worked with his brother-in-law, Henricus Hondius. Their most successful venture was to reissue the Mercator-Hondius atlas. Jodocus Hondius had acquired the plates to the Mercator atlas, first published in 1595, and added 36 additional maps. After Hondius died in 1612, Henricus took over publication; Janssonius joined the venture in 1633. Eventually, the atlas was renamed the Atlas Novus and then the Atlas Major, by which time it had expanded to eleven volumes. Janssonius is also well known for his volume of English county maps, published in 1646.

Janssonius died in Amsterdam in 1664. His son-in-law, Johannes van Waesbergen, took over his business. Eventually, many of Janssonius’ plates were sold to Gerard Valck and Pieter Schenk, who added their names and continued to reissue the maps.
