"dull paintings (including two Claudes and a Tintoretto)"

Claude Lorrain (1600-1682) was a French landscape painter described by later artist Constable as "the most perfect landscape painter the world ever saw".

Jacopo Tintoretto (1518-1594) is considered the last great painter of the Italian Renaissance. His work focuses mainly on biblical and religious themes.
