Just as the Arnold Arboretum is an invented landscape, so are the paintings in this exhibition of paintings by Nancy Sableski, which will be on view in the Hunnewell Building lecture Hall, 125 Arborway, from February 21 – May 29. While every work of art is an invention, Ms. Sableski takes this concept a step further by painting imagined landscapes that are constructed by blending multiple images taken with her cellphone. In this way she invents places that don’t exist but which clearly refer to the Arboretum. This technique allows her to examine aspects of landscape that continually capture her imagination: the interplay of powerful verticals, unpredictable diagonals, and receding horizontals. The opening reception will take place February 21 from 1 – 3. Call 617-384-5209 for more information.
