Noted 18th century landscape painter Richard Wilson, who spent much of his time in Italy, gives us a beautifully direct observation of a tree at the edge of a lake south of Rome. Though it looks like it might be a concept drawing for a Lord of the Rings movie, it’s obviously drawn from life.
I love the way his hatch marks both follow around the forms, giving them shape and volume and define the textures within them. He also shows a wonderful touch in the delicate indication of the foliage.
