The audacity of beauty lies in its ability to take over our lives and stop time. For that moment we are suspended in a state of wonder that goes beyond contemplation to pure consciousness, nerves, feelings and imagination totally open. Viewers may experience those moments frequently in “Over Time,” an exhibition of paintings by Beth Edwards that continues through Dec. 3 at Clough-Hanson Gallery. The show’s title is apropos. It’s a small retrospective gathering of 17 works, ranging from 1993 to 2015, and it represents the tendency of art to triumph over chronology.
