Thom Sokoloski’s artwork reminds us of the victims of smallpox

At about 7 last night, “The Encampment,” an installation of 100 19th-century-style tents by the Canadian artist Thom Sokoloski, was to open in an empty field at the southern tip of Roosevelt Island.

A year in the making, the tents represent the patients who once lived in the island’s smallpox hospital, the remains of which loom nearby. Inside each, volunteers would arrange artifacts to memorialize patients and other island residents. As a final touch, the tents were to be illuminated from within, so “The Encampment” would be visible from both sides of the East River, a glowing link to the area’s history.
