Striking example of Covens & Mortier's map of the World, showing California as an island.
Five additional spheres across the top of the map illustrate night and day; the earth without water; the phases of the moon, and the eastern and western hemispheres. The American portion of the map is almost portolan style in its location of place names. The map is rich with cartographic misconceptions. California is an island, there is a wonderful wide Northwest Passage and Northeast Passage, the straits of Anian are shown, along with a strait of land coming from Asia in the Terra Iesso style.
New Zealand is partially mapped, as is Australia, reflecting only the discoveries of Abel Tasman.
A marvelous compendium of 17th Century Cartographic knowledge, in gorgeous color.
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. While most of these show the equivalent of the modern state of California separated from the continent, others, like a manuscript chart by Joao Teixeira Albernaz I (ca. 1632) now in the collection of the National Library of Brasil shows the entire western half of North Americas as an island.
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.
Johannes Covens (1697-1774) was a Dutch geographic publisher based in Amsterdam. He is best known for his collaboration with fellow publisher Cornelis Mortier (1699-1783). Pierre Mortier the Elder (1661-1711) had obtained a privilege in 1690 to distribute the works of French geographers in the Netherlands. After his widow continued the business for several years, Cornelis took over in 1719.
In 1721, Mortier forged a partnership with Covens, who had recently married Cornelis’ sister. They published under the joint name of Covens & Mortier. In 1774, upon the death of his father, Johannes Covens II (1722-1794) took over his father’s share. In 1778, the company changed its name to J. Covens & Zoon, or J. Covens & son.
Covens II’s son, Cornelis (1764-1825), later inherited the business and brought Petrus Mortier IV back into the fold. Petrus was the great-grandson of Petrus Mortier I. From 1794, the business was called Mortier, Covens & Zoon, or Mortier, Covens, & Son.
The business specialized in publishing French geographers including Deslisle, Jaillot, and Sanson. They also published atlases, for example a 1725 reissue of Frederik de Wit’s Atlas Major and an atlas, with additions, from the works of Guillaume Delisle. There were also Covens & Mortier pocket atlases and town atlases. The company profited from acquiring plates from other geographers as well. For example, the purchased Pieter van der Aa’s plates in 1730. Finally, they also compiled a few maps in house. At their height, they had the largest collection of geographic prints ever assembled in Amsterdam.
