Scarce double hemisphere map of the World, featuring California as an Island, from Herman Moll's Maps Of The Several Parts Of Europe...
Moll provides a recently updated map, based upon the information which was most current at that date (although retaining the island of California).
The upper coast of America and Canada left undefined. A nice inset sphere of North Pole atop the two Hemispheres. Australia's coast is also left undefined, as are the coasts of Russia and Japan.
The popular misconception of California as an island can be found on European maps from the sixteenth through the eighteenth centuries. From its first portrayal on a printed map by Diego Gutiérrez, in 1562, California was shown as part of North America by mapmakers, including Gerardus Mercator and Abraham Ortelius. In the 1620s, however, it began to appear as an island in several sources.
The myth of California as an island was most likely the result of the travel account of Sebastian Vizcaino, who had been sent north up the shore of California in 1602. A Carmelite friar, Fray Antonio de la Ascension, accompanied him. Ascension described the land as an island and around 1620 sketched maps to that effect. Normally, this information would have been reviewed and locked in the Spanish repository, the Casa de la Contractación. However, the manuscript maps were intercepted in the Atlantic by the Dutch, who took them to Amsterdam where they began to circulate. Ascension also published descriptions of the insular geography in Juan Torquemada’s Monarquia Indiana (1613) (with the island details curtailed somewhat) and in his own Relacion breve of ca. 1620.
The first known maps to show California as an island were on the title pages of Antonio de Herrera’s Descripcion de las Indias Occidentales (1622) and Jacob le Maire's Spieghel Der Australische Navigatie (1622). Two early examples of folio-maps are those by Abraham Goos (1624) and another by Henry Briggs, which was included in Samuel Purchas’ Hakluytus Posthumus or Purchas his Pilgrimes (1625). In addition to Briggs and Goos, prominent practitioners like Jan Jansson and Nicolas Sanson adopted the new island and the practice became commonplace. John Speed’s map (1626-7), based on Briggs’ work, is well known for being one of the first to depict an insular California.
The island of California became a fixture on mid- and late-seventeenth century maps. The island suggested possible links to the Northwest Passage, with rivers in the North American interior supposedly connecting to the sea between California and the mainland. Furthermore, Francis Drake had landed in northern California on his circumnavigation (1577-80) and an insular California suggested that Spanish power in the area could be questioned.
Not everyone was convinced, however. Father Eusebio Kino, after extensive travels in what is now California, Arizona, and northern Mexico concluded that the island was actually a peninsula and published a map refuting the claim (Paris, 1705). Another skeptic was Guillaume De L’Isle. In 1700, De L’Isle discussed “whether California is an Island or a part of the continent” with J. D. Cassini; the letter was published in 1715. After reviewing all the literature available to him in Paris, De L’Isle concluded that the evidence supporting an insular California was not trustworthy. He also cited more recent explorations by the Jesuits (including Kino) that disproved the island theory. Later, in his map of 1722 (Carte d’Amerique dressee pour l’usage du Roy), De L’Isle would abandon the island theory entirely.
Despite Kino’s and De L’Isle’s work, California as an island remained common on maps until the mid-eighteenth century. De L’Isle’s son-in-law, Philippe Buache, for example, remained an adherent of the island depiction for some time. Another believer was Herman Moll, who reported that California was unequivocally an island, for he had had sailors in his offices that claimed to have circumnavigated it. In the face of such skepticism, the King of Spain, Ferdinand VII, had to issue a decree in 1747 proclaiming California to be a peninsula connected to North America; the geographic chimera, no matter how appealing, was not to be suffered any longer, although a few final maps were printed with the lingering island.
Herman Moll (c. 1654-1732) was one of the most important London mapmakers in the first half of the eighteenth century. Moll was probably born in Bremen, Germany, around 1654. He moved to London to escape the Scanian Wars. His earliest work was as an engraver for Moses Pitt on the production of the English Atlas, a failed work which landed Pitt in debtor's prison. Moll also engraved for Sir Jonas Moore, Grenville Collins, John Adair, and the Seller & Price firm. He published his first original maps in the early 1680s and had set up his own shop by the 1690s.
Moll's work quickly helped him become a member of a group which congregated at Jonathan's Coffee House at Number 20 Exchange Alley, Cornhill, where speculators met to trade stock. Moll's circle included the scientist Robert Hooke, the archaeologist William Stuckley, the authors Jonathan Swift and Daniel Defoe, and the intellectually-gifted pirates William Dampier, Woodes Rogers and William Hacke. From these contacts, Moll gained a great deal of privileged information that was included in his maps.
Over the course of his career, he published dozens of geographies, atlases, and histories, not to mention numerous sheet maps. His most famous works are Atlas Geographus, a monthly magazine that ran from 1708 to 1717, and The World Described (1715-54). He also frequently made maps for books, including those of Dampier’s publications and Swift’s Gulliver’s Travels. Moll died in 1732. It is likely that his plates passed to another contemporary, Thomas Bowles, after this death.
