About The Heights over Foilhummerum Bay, Valentia, the William Corey Heading Seawards, Laying the Shore-end of the Atlantic Telegraph Cable, July 7th, 1866
The artist and artwork
Robert Charles Dudley made The Heights over Foilhummerum Bay, Valentia in 1865–66, recording the William Corey heading seaward after laying the Irish shore end of the Atlantic telegraph cable on July 7, 1866. He built the drawing in watercolor over graphite, then used gouache to sharpen clouds, mountain faces, rocks, sails, and figures. Dudley created watercolors and oils documenting the cable expeditions, making machinery, ships, labor, and coastal geography visible as parts of one undertaking.
The world around it
A telegraph wire beneath the Atlantic promised to reduce communication between Europe and North America from ten or twelve days by steamer to minutes. Cyrus W. Field and the Atlantic Telegraph Company achieved a connection in 1858, but it failed after three weeks. Repeated attempts by investors, engineers, technicians, sailors, and two navies finally produced two working cables in July and September 1866. The scene marks a turning point in global communications, but also the start of a risky voyage: the fleet did not leave across the Atlantic until July 12. Field gave Dudley's works, cable specimens, medals, and memorabilia to The Met in 1892.
A detail to notice
The technology that changes the world is almost impossible to see. Dudley places ships and working parties along a thin strip of quiet water beneath Foilhummerum's immense purple-gray heights and a sky occupying nearly half the sheet. Masts become fine vertical marks; a boat of people floats near shore, and more figures gather on the rocky point. At right, two brightly colored onlookers and a black-and-white dog occupy the closest ledge, yet even they are small. The cable disappears into the landscape. By refusing a single heroic engineer or machine, Dudley makes scale the surprise: a nearly invisible line, handled by tiny bodies, is about to collapse an ocean's communication time.
