The mythological figures of Tyche and Nemesis appear often in the paintings of the late 1970s. In the 1980s, the goddess of fortune and the goddess of retribution, dominate the paintings, which are frequently circular in shape. Inspired by Albrecht Dürer’s 1502 engraving of the winged Nemesis, who travels on her celestial globe, holding a bridle to bind man’s pride and a goblet containing rewards for the just, Keller’s Nemesis, who does not have wings, rides her celestial globe in close collaboration with aircraft, clutching her shopping bag (instead of a goblet) and a lasso (rather than a harness). She soars over sepia farm landscapes, often over a sea on which a container ship, on its entry into New York Harbor, shows a horizon line at its stern, but not at its prow.
