Chart of the Sandwich Islands, 1785

Dotted lines fan out across this chart like threads, and each one marks the path of a ship. They belong to the Resolution and the Discovery, the two vessels of Captain James Cook's third and final voyage, which reached the Hawaiian archipelago in 1778. Cook named the group the Sandwich Islands after the Earl of Sandwich, then First Lord of the Admiralty, and the names printed here reflect how English ears heard Hawaiian words at the time: Owhyhee for Hawai'i, Mowee for Maui, Woahoo for O'ahu, Atooi for Kaua'i. The engraving was published around 1784 to 1785 in the official atlas accompanying the voyage account, with much of the survey work credited to Henry Roberts, a young officer who sailed with Cook and turned rough shipboard measurements into finished plates.

The large inset takes up the whole lower left corner, and its subject is not accidental. It shows Kealakekua Bay on the west coast of Hawai'i Island, drawn in unusual detail with soundings, a shaded cliff face, and the shape of every small inlet. This is where Cook was killed on 14 February 1779, during a confrontation on the shore after a dispute over a stolen boat. The chart never says so loudly, but the decision to enlarge this one small bay above all others tells you what its makers were thinking about.

Hand coloring gives the islands their coral pinks, mustards, and greens, added after printing by workers who tinted copperplate engravings by the batch. The style belongs squarely to Enlightenment surveying: careful coastlines where ships actually sailed, vaguer edges where they did not, and open ocean left blank rather than filled with sea monsters. Look at the empty stretches between islands and you are seeing honesty about the limits of what the crew had measured.
