Expedition
Expedition
Agate created many artworks during his service with the United States Exploring Expedition of 1838–1842 under Charles Wilkes. He was especially good at botanical illustrations, and was the designated portrait and botanical artist of the expedition. The United States Exploring Expedition passed through the Ellice Islands and visited Funafuti, Nukufetau and Vaitupu in 1841. During the visit of the expedition to the Ellice Islands (now known as Tuvalu) Alfred Thomas Agate recorded the dress and tattoo patterns of men of Nukufetau. Agate created the first known picture of Mount Shasta. Agate contributed more than half (173 of 342) of the sketches and paintings reproduced as lithographs illustrating the five volumes of the expedition's reports. He sketched the Oregon Territory, including a look into a Chinook Lodge, an Indian Burial Place, an Indian Mode of Rocking Cradle, and a picture of the wreck of one of the expedition's sailing ships at the mouth of the Columbia River.
After the expedition
After the expedition
Agate lived in Washington, D.C., from 1842 onward, but his health suffered severely from the expedition and he died four years later of consumption. On Agate's death in 1846, the drawings passed to his widow, Elizabeth Hill Kennedy Agate, who later married Dr. William J. C. Du Hamel of Washington, D.C. In 1926, one of her daughters from this marriage, Elizabeth A. Du Hamel, sold them to the Naval Historical Foundation. The Naval Historical Foundation donated Agate's artwork to the Navy Art Collection in 1998.
