Contributed by Sharon Butler / Few artists – even among those dedicated to the landscape – would look at a body of water and think, “OK, I’m going to spend the next 30 years painting this.” Yet, year by year, Eric Wolf has done just that, driven by a fascination with the daily transformation of water’s surface, its complementary relationship to air, its connection with people, and the peculiarly seductive power of black ink on paper. “Two Waters,” on view at Abri Mars, spans three decades of Wolf’s en plein air ink painting, which he did exclusively at two sites: a pond in Chatham, New York, and a lake in Rangeley, Maine.
