A Universal Geographic Clock

Fine advertisement for Zacharias Landteck’s universal geographic clock that tells the time around the world and shows the progression of the sun across the northern hemisphere.

The clock is a marvel of engineering, as the text explains. The standing table clock has a face that includes twenty-four hours, rather than the usual twelve. It also contains a concentric rotating ring with the months of the year and the signs of the zodiac. At center is a map of the northern hemisphere that can be covered by a rotating shaded glass disc. Together, the clock’s rings would let a user see their own time, but also to calculate the local time, sunrise, and sunset of any meridian around the world.

The map shows California as an island. It includes a large landmass crossing the North Pacific; this Compagnie Land was supposedly sighted in the mid-seventeenth century and was later exaggerated by mapmakers into a continent-sized behemoth. A possible Northwest Passage is suggested, as the precise coastlines near the North Pole are unfinished.

The clock is not only a fount of information, but an aesthetically rich item as well. It is heightened in silver and the finest of woods and is meant to serve as a handsome addition to any parlor or office.

The clock is an instrument, however, not just a novelty. Based in Nuremberg, Homann was at the center of local and regional trade. The Holy Roman Empire had contacts across the globe, as did its merchants and officials. While never intended for travel, the clock, and this broadside, does engage with the ongoing discussion about differences in time over long distances, an observation that played into one of the most pressing scientific issues of the day, how to calculate longitude accurately.

While the answers to the longitude question were complex and multiple, clocks did prove an important part of that answer. If a clock could be made to tell time consistently while traveling—i.e. to not lose time due to jostling, the elements, or the mechanism—then a user could compare the clock’s time to the local time and thus calculate their longitude relative to their point of departure.

John Harrison would develop just such a clock—several of them, in fact—over the decades of the mid-eighteenth century. The clocks were tested on a series of voyages, including those of James Cook and other Pacific explorers, in the later-eighteenth century. Eventually, every ship carried a clock based on Harrison’s design that could keep time at sea.

North Pacific chimeras: Yesso, De Gama, and Compagnie Land

The etymology of the idiom Yesso (Eso, Yeco, Jesso, Yedso) is most likely the Japanese Ezo-chi; a term used for the lands north of the island of Honshu. During the Edō period (1600-1886), it came to represent the ‘foreigners’ on the Kuril and Sakhalin islands. As European traders came into contact with the Japanese in the seventeenth century, the term was transferred onto European maps, where it was often associated with the island of Hokkaido. It varies on maps from a small island to a near-continent sized mass that stretches from Asia to Alaska. 

The toponym held interest for Europeans because the island was supposedly tied to mythic riches. Father Francis Xavier (1506-1552), an early Jesuit missionary to Japan and China, related stories that immense silver mines were to be found on a secluded Japanese island; these stories were echoed in Spanish reports. The rumors became so tenacious and tantalizing that Abraham Ortelius included an island of silver north of Japan on his 1589 map of the Pacific.

Yesso is often tied to two other mythical North Pacific lands, Gamaland and Compagnies Land. Juan de Gama, the grandson of Vasco de Gama, was a Portuguese navigator who was accused of illegal trading with the Spanish in the East Indies. Gama fled and sailed from Macau to Japan in the later sixteenth century. He then struck out east, across the Pacific, and supposedly saw lands in the North Pacific. These lands were initially shown as small islands on Portuguese charts, but ballooned into a continent-sized landmass in later representations.

Several voyagers sought out these chimerical islands, including the Dutchmen Matthijs Hendrickszoon Quast in 1639 and Maarten Gerritszoon Vries in 1643. Compagnies Land, often shown along with Staten Land, were islands sighted by Vries on his 1643 voyage. He named the islands for the Dutch States General (Staten Land) and for the Dutch East India Company (VOC) (Compagnies, or Company’s Land). In reality, he had re-discovered two of the Kuril Islands. However, other mapmakers latched onto Compagnies Land in particular, enlarging and merging it with Yesso and/or Gamaland.

In the mid-eighteenth century, Vitus Bering, a Danish explorer in Russian employ, and later James Cook would both check the area and find nothing. La Perouse also sought the huge islands, but found only the Kurils, putting to rest the myth of the continent-sized dream lands.

California as an island

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.

Johann Baptist Homann Biography

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.
