"La Bruma" (mist), by Raul Diaz, in his show through Nov. 12 at the Adelson Galleries, Boston. Adelson says: "The ... boats; empty and idle vehicles without a conductor, float on still water. This reoccurring symbol in Diaz’s oeuvre may represent life’s voyage, and the balance between effort and reflection required to move forward. Moments of serenity often follow periods of intensity, exemplified poetically in the artist’s course of creation.''
