Polishing the Glass Ceiling is a three-hour performance set in the Chicago Cultural Center. Working on hands and knees, I silently polished floor and wall mosaics with my grandmother's handkerchief. Moving into the vaulted Preston Bradley Hall, I stood up and burnished the walls, stretching my arms toward the Tiffany ceiling high above. At the culmination of these domestic gestures, I read aloud the names of thirty female authors to insert them into this former Chicago Public Library alongside the thirty canonical male authors whose names are inscribed on the walls. This performance of symbolic acts aims to honor and make visible the unacknowledged labor of female artists in this public building.
