Performers will draw on works of art in the Roman show in order to explore representations of movement and space in the antique world. Performances are Dec. 13-14 at 7 p.m. at the IMA. Admission is charged to the exhibit. Meet in the Efroymson Family Entrance Pavilion. The IMA is located at 4000 Michigan Road. Call 317-923-1331 for information.
