Though it sounds like something out of Disney World, the Atlanta Cyclorama was created in the 1880s, and the concept -- a huge, 360-degree cylindrical painting viewed from a rotating platform -- dates back a century earlier. Cycloramas were the rage of 18th- and 19th-century Europe, Russia, Japan, and, later, the United States, depicting subject matter ranging from the splendors of Pompeii to Napoleonic battles. The one you'll see here -- a 42-foot-high cylindrical oil painting, 358 feet in circumference (on about 16,000 sq. ft. of canvas) -- depicts the events of the Battle of Atlanta, on July 22, 1864, in meticulous detail. It took 11 Eastern European artists, working in the United States in the studio of William Wehner, 22 months to complete the project.
