Today concludes the yearlong exhibition “Space Exploration: In Rejection of Frontiers” on display at the Tisch Library at Tufts University. The title refers to the built space, not outer space, and the complexities and subtleties at play in the deceptively simple task of inhabiting spaces. The exhibition mines Tufts University Art Galleries’ permanent collection for representations that subtly and powerfully confront reductive, spatial frameworks with nuance and curiosity.
