The First Scientific Age of Pacific Exploration--Dated Using the French Revolutionary Calendar!
Interesting double hemisphere map of the world highlighting the encounters of Captain James Cook on his three voyages of exploration in the Pacific.
Dezauche was known for skillfully updating the work of Guillaume De L’Isle and Philippe Buache. Here, the most noteworthy changes are the additions from the Cook voyages—the tracks of his second and third voyages are here, but the geographic observations of the first are also prominent. Hawai’i is included, as is the reformation of Australia to include the East Coast, and a more accurate delineation of New Zealand.
Hope continues for a Northwest Passage, although there is acknowledgment that ice flows block the passage above Alaska. An inland passage is not ruled out, as northern North America is described as unknown, “l’Interieur de ce Pays est Inconnu.” To the south, there is no Antarctica in sight, although Cook’s three crossings of the Antarctic Circle on his second voyage are marked as having met with “Montagnes de Glaces,” or mountains of ice.
The eastern coast of Australia had recently been made into a penal colony with the arrival of the First Fleet (1788) at Botany Bay. This eastern coast has toponyms resulting from Cook’s first voyage, when he sailed up the east coast and nearly crashed into the Great Barrier Reef. The west coast is labeled with names that refer to earlier Dutch encounters with the west coast. Some of these western toponyms are also from Dampier’s encounter with the continent in 1699, when he passed harsh judgement on the Aboriginal peoples and named Sharks Bay, here “Scharks Bay.”
Away from the Pacific, the United States (Etats Unis) is named. Farther north, Greenland and mainland North America are connected, a common assumption at the time, as ice blocked the passage between the landmasses and Baffin Bay remained little explored. In Hudson’s Bay, the Eau de Wager and the Chesterfield [Inlet] show two of the latest attempts to find the Northwest Passage, by the Furnace in 1741-2 and by the Dobbs Galley and California in 1746-7.
A floral cartouche in the lower center, between the hemispheres, carries a short explanation from Dezauche. He explains that the map is intended to highlight Cook’s voyages and recent discoveries made in the three decades prior to the map being published. He invokes his connection to the famous Buache to assure his customers of his skill and cartographic lineage. Clouds and sun stream along the top of the map, with furling banners bearing the title.
This 1800 imprint has one interesting update: it uses the French Republican calendar. Implemented during the French Revolution, the calendar was in use from 1793 to 1805. The new calendar was part of a campaign to remove religious and royalist references and influences from civic life. The calendar, which used 1792 as year one, was split into twelve months of three ten-day weeks. The tenth day was for rest and festivity. The extra days needed to make up a year were added after the twelfth month and were called complementary days. This map was published in year nine, which ran from September 23, 1800 to September 22, 1801.
The Transit of Venus is one of the rarest predictable astronomical phenomena, occurring twice in eight years and then not again for over one hundred years (in a 243-year cycle). Observing the time it takes for Venus to transit across the sun can help to calculate the size of the solar system and the distance from the Earth to the Sun. In 1761, scientific societies sought to record the Transit from posts around the world. However, many of the observations were flawed or thwarted by the weather, especially those arranged, in haste, by the Royal Society of London. Determined to not repeat the same mistake, the Royal Society planned a South Sea voyage to view the 1769 Transit in concert with the Royal Navy, as the southern Pacific would be one of the places where the Transit was visible.
The Admiralty chose Lieutenant James Cook to command the expedition, based on his aptitude for charting and instrumentation. He was joined by Joseph Banks, a wealthy young botanist, and his retinue of scientists and artists. In addition to observing the Transit, Cook was secretly instructed to seek out and claim any potentially-useful territory or resources that his ship, Endeavour, came across.
Cook and his crew sailed from Plymouth on August 25, 1768. It sailed south, to Tierra del Fuego, and then to its destination for the Transit: Tahiti. There, three groups observed the Transit, although their results were imprecise. When the Endeavour left Tahiti in July 1769; on board was a new member of the party, the Rai’aitean priest and navigator Tupaia, along with his servant, Taiato.
The ship headed south, arriving in New Zealand in early October. There, Tupaia found that he could understand and speak with the local people, the Māori. However, this did not prevent several violent incidents that resulted in deaths. While charting the coastline, Cook and the voyage astronomer, Charles Green, observed the Transit of Mercury. The ship sailed round the southern tip of the South Island, proving it was not connected to a southern continent.
Next, the Endeavour set out east, encountering the east coast of Australia in April 1770. They were the first Europeans to do so. After stopping at a place they called Botany Bay, the ship turned north, skirting the coast. Endeavour ran aground on the Great Barrier Reef; while the ship was saved, they had to stop for repairs at Waalumbaal Birri, or Endeavour River. Here, the Europeans saw their first kangaroo and learned its name from the local people, the Guugu Yimithirr. They nearly ran aground again, but narrowly averted disaster and made for Jakarta, then known as Batavia.
In Batavia, many members of the crew became ill. More than two dozen men, including Sydney Parkinson, the voyage artist, the aforementioned Charles Green, and Tupaia, died in Jakarta or at sea soon thereafter. Weakened, the Endeavour called at the Cape of Good Hope and returned to the Thames in July 1771.
Cook’s first voyage was considered a success. The Admiralty chose to send him to the Pacific again, this time to focus on finding and charting Terra Australia incognita, if it existed. This time, Cook was in command of the Resolution and accompanied by the Adventure, captained by Tobias Furneaux.
The ships departed Plymouth on July 13, 1772. They made for the Cape of Good Hope and then sailed south, in search of land. They reached an ice sheet and could not find a break to sail through. The crew melted ice for fresh water and the expedition artist, William Hodges, drew eerie pictures of looming icebergs. On January 17, 1773, the ships crossed the Antarctic Circle, the first ships known to have done so.
Separated in fog, the ships headed toward New Zealand. They rendezvoused in Queen Charlotte Sound, where they traded with the Māori. The Māori inquired as to location of Tupaia and were sad to hear that he had died.
The ships returned to Tahiti, where they found the politics of the island had shifted and there was a new leader, Tu, to consult. Mai, a Rai’atean man, joined the Adventure, while Hitihiti joined the Resolution. The former became the first Polynesian to visit Britain, while Hitihiti returned home after sailing to Tonga, the Antarctic, New Zealand, and Easter Island.
Cook and his men next sailed to Tonga and then back to New Zealand. En route, the ships were separated again. Resolution left for southern waters without Adventure; Furneaux decided to return to Britain, leaving Cook in the Antarctic.
In December 1773 and January 1774, Resolution crossed the Antarctic Circle for the second and third times. They reached 71°10’ South, the farthest south any ships had sailed; the record would stand until 1823. He had decidedly proven that the great southern continent was nothing more than a myth.
Returning north, Cook called at Rapa Nui, or Easter Island, and his men marveled at the Moai, large statues that stand guard on the island. The Resolution returned to Tahiti, and then called at Niue, Nomuka, Vanuatu, New Caledonia, and Norfolk Island. After another visit to New Zealand, they sailed east to Tierra del Fuego. In the Atlantic, Cook named South Georgia and the South Sandwich Islands. On the homeward stretch, Resolution visited St. Helena and then anchored in Portsmouth on July 30, 1775.
After two Pacific cruises that observed the Transit of Venus, charted New Zealand, the eastern coast of Australia, and many islands; and disproved the existence of a vast southern continent, Cook’s third voyage focused on searching for the Northwest Passage. It was also tasked with the return of Mai, a Ra’iatean man and the first Polynesian visitor to Britain, who had joined Cook’s second voyage.
Cook in the Resolution was joined by Charles Clerke in the Discovery. Resolution sailed in July from Plymouth, rounded the Cape of Good Hope, visited the Kerguelen group in the Southern Indian Ocean, then called at Tasmania before heading to New Zealand.
In the spring of 1777, the ships sailed north, first to Tonga, and then to Tahiti. They left Mai on Huahine in a wooden house built for him by the crew. Cook continued north and became the first European to encounter the Hawaiian Islands, in January 1778.
During the warm months (in the northern hemisphere) of 1778, Cook and his crew charted the northwestern coast of North America, calling at Nootka Sound and Prince William Sound. They went up the Cook Inlet, which they thought could be a Northwest Passage, but it proved to be a false start. Heading west, they skirted the Aleutians and sighted the Asian coast. In January 1779, they returned to Hawai’i to resupply and rest.
In Kealakekua Bay, Cook was greeted warmly by the Hawaiians. They stayed for three weeks, enjoying the considerable hospitality of the people. In early February, the ships set out for another northern tour, but only a few days from Hawai’i the Resolution’s mast was damaged, forcing their return.
This time, they were not welcomed by crowds. During a dispute over a stolen boat, a scuffle broke out. When it was over, sixteen Hawaiians, four marines, and Cook were dead.
Clerke took command. He forced the Hawaiians to give him Cook’s remains, which were buried at sea. He then led the ships north, passing through the Bering Strait before turning back due to ice. In August of 1779, Clerke too died, of consumption, while near Kamchatka. A third commander, John Gore, then had to lead the ships home.
The ships sighted Japan on their southward journey before calling at Macao. There, they made sizeable profits by selling sea otter pelts, kickstarting a new industry. By April 1780, the Resolution and Discovery were back at the Cape of Good Hope. They returned to Britain via the Orkneys, anchoring in the Thames on October 7, 1780.
Jean-Claude Dezauche (fl. 1780-1838) was a French map publisher. He edited and reissued the maps of Guilluame De L’Isle and Philippe Buache, two of the most skilled mapmakers of the eighteenth century. He acquired the plates of these two men’s work in 1780 from Buache’s heir, Jean Nicholas Buache. Dezauche worked in the Depot de la Marine, as had the elder Buache.
