What are the two pieces of art that Tully takes with him on his trip aboard the Caribbean Soul?

On his trip aboard the Caribbean Soul, Tully takes his two prized possessions of art. One is a valuable engraving and the other is a painting entitled The Patron Saint of Lightning. The painting is of a woman on a cloud with light extending from her to the stormy seas below. Tully purchased it at a flea market and then discovered it is St. Barbara, the patron saint of those besieged by lightening.
