"Order and Chaos'' (diptych, oil on copper), by Nora Charney Rosenbaum, in the show "Ghost Fish,'' at Galatea Fine Art, Boston, May 30-July 1. She says: "The underlying theme of this group of work is the movement of water as a metaphor for my recent life experiences. Seeking predictability amidst chaos, equilibrium in turbulence, I've been carried along by currents either willingly or with resistance.''
