I've saved the original thread, and I'll transfer the posts across as time permits.
Painting of the Day (original series):
by Nicolas Poussin, a French painter of the 17th century who worked for most of his career in Rome.
This is one of his series The Four Seasons, painted near the end of his life. Each depicts a Biblical scene. In this case the subject is Noah's flood. You can see the Ark in the background on the left.
