The first painting is by Claude Lorraine. The one below is by Turner. Lorraine was a great influence on the young Turner. He took his initial conception of deep atmospheric space in landscape painting and it’s possibilities from Claude. In the bottom painting, Turner painted a full scale copy presumably from memory. He had a prolonged stay at the home of his patron, the Earl of Egremont, and it became the painting to which he became the most attached. Five years after the experience he painted a full scale copy presumably from memory. The obvious difference being the replacement of Lorrain’s biblical figures with figures from Ovid’s Metamorphosis. I view it as a visual pun, Turner engaging in an act of metamorphosing a Lorrain into a Turner.
