Ideas presented by Freud appear all over the place; even pieces that were written before Freud have Freudian ties. The play Antigone, for example, displays the unrepressed id and a repressed superego and the detrimental results of both. In Antigone, Ismene represented the superego and Antigone represented the id. The results of the unbalanced psyche were catastrophic. The pieces displayed in this exhibit reflect how repression or lack thereof, affected the two women and caused the events to unfold as they did in Antigone.
