Ánima, Silueta de Cohetes (Firework Piece), Oaxaca, Mexico, 1976
In this past week's Penny Stamps lecture, Wangechi Mutu referenced Ana Mendieta several times as an important influence in her work. Mendieta was a Cuban-American artist (1948 – 1985) famous for her performance art and "earth-body" sculptural, photographic, and video work. Here is an interesting article from the Tate written about her and Nancy Spero.
