Pocket globe London, between 1775 and 1798 Re-edition of the globe of Hermann Moll (1678-1732) dated 1719 The globe is contained in its original case, which itself is covered in shark skin. There are slight gaps in the original paint on the sphere. The case no longer closes. The sphere measures 2.7 in (7 cm) in diameter whereas the case measures 2.9 in (7.4 cm) in diameter. lb 0.22 (kg 0.1) The globe is made up of twelve printed paper gores aligned and glued to the sphere. In the North Pacific Ocean there is a cartouche with the inscription: A Correct Globe with the new Discoveries. The celestial globe is depicted on the inside of the box and is divided into two hemispheres with the cartouche: A correct globe with ye new cons relations of Dr. Halley & c. It shows the ecliptic divided into the days of the zodiacal calendar and the constellations represented as animals and mythological figures. On the globe are delineated the equinoctial line, divided by degrees and hours, the ecliptic and the meridian (passing west of Greenwich). The continents are shaded and outlined in pink, green and yellow. It shows: the Cook routes; a wind rose in the Southern Indian Ocean; Antarctica without land; Africa with Negroland (Hermann Moll is considered the first geographer to name the West African region in his 1727 map. (Encyclopaedia Britannica, ed. 1902, under "States of Central Africa"); Tartary in Central Asia; the Mogul kingdom in northern India; in North America only New England, Virginia, Carolina, Florida, Mississippi are identified; California is already a peninsula; the northwest coast of America is "unknown parts" (Alaska is not described and it is only partially delineated, it was to become part of the United States in 1867); Mexico is named "Spain"; Central South America "Amazone America". Australia (which was to be so named after 1829) is called New Holland. The route of Admiral Anson is traced (1740) and the trade winds are indicated by arrows. (See Van der Krogt, P., Old Globes in the Netherlands, Utrecht 1984, p. 146 and Van der Krogt, P. - Dekker, E., Globes from the Western World, London 1993, pp. 115.) Elly Dekker, comparing Moll’s 1719 globe and his re-edition (of which the one described above is a sample), identifies the differences between them: the two editions are quite similar to each other, but in the "anonymous" globe, compared to the previous globe of 1719, California looks like a proper peninsula - the reports of the Spanish explorers of the region had given rise to uncertainty over whether it was connected to the mainland or not. The geographical nature of California was confirmed after the explorations of Juan Bautista de Anza (1774-1776). The routes of Dampier's journey were partially erased and the route of Captain James Cook's first voyage was superimposed on them, and the geography of Australasia was adapted accordingly, including the denomination of the Cook Strait. See Dekker, Elly, Globes at Greenwich, 1999. An important ante quem element is represented by Tasmania: it is not separated from Australia by the Bass Strait...

Pair of 12-inch table globes William Harris London, 1832 and 1835 Slight abrasions from use; few cracks lb 11 each (kg 5) The two terrestrial and celestial globes rest in their original Dutch style stands with four supporting turned wood columns. Each one measures 12 in in height x 16.5 in in diameter with the diameter of the spheres measuring approximately 12 in; 48 cm in height x 42 cm in diameter x 31 cm diameter of the spheres. The 12 inch measure was the most frequently used by British manufacturers of globes of this period. Each globe is composed of two series of twelve printed paper gores, aligned and glued onto plaster spheres. The brass circle of the meridian bears engravings...

Ptolemaic armillary sphere Charles-François Delamarche Paris, ante 1798 Wood and papier-mâché covered with printed and partly hand-colored paper It measures 16.37 in in height x Ø 10.94 in (41.60 cm - Ø 27.80 cm) It weights 2.33 lb (1,058 g) State of conservation: consistent with its age and use, the paper shows some signs of use, stains and abrasions. The sphere is Ptolemaic, with the Earth placed at its center, surrounded by the Moon and the Sun mounted on two metal arms. The sphere is composed of six horizontal and two vertical rings (armillae), each bearing graduations and its own name. The first horizontal ring is illegible. The others, in descending order are: North Pole, Tropic of Cancer, Equator, Tropic of Capricorn, South Pole. The vertical rings consist of two double meridians. The sphere is then connected to the large meridian by two pins, a vertical ring inserted perpendicularly into the circle of the Horizon, in turn supported by four semicircles connected to the turned and black-stained wooden base. Each element is covered with printed paper. It contains various pieces of information: latitudes, length of days, names and zodiac symbols, calendar, wind directions, etc. The vertical circles mention the latitudes and longitudes of different cities: Rome, Bordeaux, Madrid, Boston, Batavia (Jakarta), Acapulco, etc. Even the small terrestrial globe is covered with printed paper: continents and oceans appear with numerous geographical markings indicating the most recent explorations. In the Pacific Ocean, west of South America bears the following inscription: GLOBE TERRESTRIAL à Paris chez Delamarche Géog Rue du Foin Jacques Au Collège de M.e Gervais The North American coasts are well delineated and California appears correctly as a peninsula - reports from Spanish explorers in the region had given rise to confusion as to whether it was connected to the mainland or not. The geographical nature of California was confirmed after the explorations of Juan Bautista de Anza (1774-1776). Alaska is not described and is only partially traced; it would become part of the United States in 1867. Various Pacific islands are indicated. Australia (the name definitely used from 1824) is called "Nouvelle Hollande." Tasmania is still represented as a peninsula and this is an important detail for the dating of our armillary sphere. The island is separated from Australia by Bass Strait, which was crossed by Matthew Flinders for the first time in 1798, showing that it was not a peninsula. Delamarche certainly would not have waited a long time to update such an important geographical datum: presumably he did so shortly after receiving the news. Charles-François Delamarche (1740-1817) founded his laboratory around 1770 and, in a few years, he became the most famous French cartographer and globe maker between the 18th and 19th centuries. After having acquired the laboratory of the late Didier Robert de Vaugondy (1723-1786; himself a renowned cartographer who continued the family business founded by his grandfather Nicolas Sanson in the seventeenth century) and after having purchased, between 1788 and around 1800, the businesses of Jean-Baptiste Fortin (1750-1831) and Jean Lattré (around 1750-1800), he began to call himself "Successeur de MM. Sanson and Robert de Vaugondi, Géographes du Roi and de M. Fortin, Ingénieur-mécanicien du Roi pour les globes et les sphères." Thus, at the end of the eighteenth century, Delamarche possessed the warehouse stocks, as well as the manufacturing skills of the globes of his main rivals in Paris. In addition to this aggressive acquisition policy, the key to its success also lay in the combination of high-quality cartography combined with extremely attractive globes and armillary spheres; and, of course, its famous red paint finishing touch. His laboratory was located on Rue de Foin St Jacques "au Collège Me. (or "Mtre") Gervais" in the Latin Quarter of Paris until around 1805, when he moved to rue du Jardinet No. 13. On the death of Charles-François in 1817, the reins of the company passed to his son Félix (1779-1835), who continued to publish, often in collaboration with the engraver Charles Dien, Sr. In 1835 the company first moved to rue du Jardinet No. 12 and a little later to rue du Battoir No. 7.
