Salomon van Ruysdael’s "Fishing Boats on a River," likely painted in the mid-17th century, is oil on canvas. The smooth application of the paint mimics the tranquil surface of the water. Oil paint, developed in the early 15th century, allowed artists to create subtle gradations of tone and texture, and capture realistic effects of light, as we see here. The gray skies and calm water convey a sense of stillness that is reflected in the muted colors of the materials. The painting gives us a glimpse into the lives of the working class of the Dutch Golden Age. Van Ruysdael has captured the boats and figures with enough detail that we understand the labor involved in fishing. We also get a sense of the fishermen's reliance on natural materials such as wood, canvas and rope. Paying attention to the materials and the making allows us to appreciate the ways in which art can provide insight into the culture and economy of its time.
