This year marks the sesquicentennial of the fall of Fort Sumter, and the start of the Civil War. Olana’s exhibition: Rally 'round the Flag: Frederic Edwin Church and the Civil War on view in the Evelyn and Maurice Sharp Gallery at Olana is one of the first exhibitions in the multi-year, regional and national commemoration of the conflict. The exhibition opens May 26 and runs through October 30, 2011, and features Frederic Church’s most patriotic work, Our Banner in the Sky, a sensational sunrise resembling a Union flag, as well as numerous oil and pencil sketches related to the war and rarely on view. The exhibition is also the first retrospective of the very talented and little known artist John S. Jameson (1842-1864). Image: Frederic Church, Our Banner in the Sky, 1861. (Olana)
