In early 2001, for just a couple of months, the skylights were opened on the cavernous underground rooms at the Henry Art Gallery and the sun shone down on one work of art especially: a rectangle of glowing orange pollen, painstakingly collected from hazelnut trees by the artist Wolfgang Laib. People just stared, taking it in as if it were radiating nutrition. Now, the German artist’s piece goes back on view, paired with another work made 125 years earlier, Winslow Homer’s late 19th-century painting An Adirondack Lake, also from the Henry’s collection. The painted scene is set at dusk, when the light is unreal. (Henry Art Gallery, 4100 15th Ave NE,, 11 am–4 pm, $10)
