Happy Birthday David Cox!! The English painter was born in 1783. He was a watercolorist and preferred painting in North Wales, although he made painting trips to Holland, Belgium and France. He wrote several books on the topic, the most well known was Treatise on Landscape Painting and Effect on Water-colours. Purely by accident he found a heavy absorbent wrapping paper suited his needs for watercolor and he eventually marketed it as Cox Paper (still available today!). The painting below is titled In the Hayfield.
