First state of Homann's double hemisphere map of the World.
Decorative double hemisphere map of the world, richly embellished with celestial models of the northern and southern hemispheres and other natural phenomena.
The map includes many famous cartographic inaccuracies. It also shows an incomplete Australia, although with place names and notes of the early discoverers included. The east coast of New Zealand is shown, along with the Tracts of Tasman's 1642 voyage and Magellan's Voyage. The detail in SE Asia is very interesting for the period, as is the treatment of Japan and the Northwest Coast of America.
The allegorical scenes around the map are a rich combination of science, fantasy, and artwork, including two celestial hemispheres, Mt. Etna erupting, numerous natural phenomena of land and sea, and representations of movements of the sun. Numerous cherubs and windheads, representations of the stars, sun and moon, and other decorative features are shown. California is shown as an island, with a highly conjectural coastline.
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 Ascensión, 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 Contratación. However, the manuscript maps were intercepted in the Atlantic by the Dutch, who took them to Amsterdam where they began to circulate. Ascensión also published descriptions of the insular geography in Juan Torquemada’s Monarquia Indiana (1613) (with the island details curtailed somewhat) and in his own Relación breve of ca. 1620.
The first known maps to show California as an island were on the title pages of Antonio de Herrera’s Descripción de las Indias Occidentales (1622) and Jacob le Maire's Spieghel Der Australische Navigatie (1622). Two early examples of larger 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.
Johann Baptist Homann (1663-1724) was a mapmaker who founded the famous Homann Heirs publishing company. He lived his entire life in Bavaria, particularly in Nuremberg. Initially, Johann trained to become a priest before converting to Protestantism and working as a notary.
In 1702, Johann founded a publishing house that specialized in engravings. The firm flourished, becoming the leading map publisher in Germany and an important entity in the European map market. In 1715, Johann was named Imperial Geographer to the Holy Roman Empire by Charles VI and made a member of the Prussian Academy of Sciences. Most importantly for his business, his reputation and contacts gained him imperial printing privileges which protected his publications and recommended him to customers. Johann is best known for this Grosser Atlas ueber die ganze Welt, or the Grand Atlas of the World, published in 1716.
After Johann died in 1724, the business passed to his son, Christoph (1703-1730). Upon Christoph’s early death, the company passed to subsequent heirs, with the name of the company changing to Homann Erben, or Homann Heirs. The firm continued in business until 1848.
