Interestingly, depicting the sun in a painting is a very recent invention. I haven’t seen a single painting in any museum where the sun is depicted above the horizon. Well, maybe with the exception of the Impressionists, Monet’s is very symbolic. In modern works, it appears more often. But in half, it’s a trace from a photograph.
Update: Turns out Aivazovsky has a lot of this. But he produced so many paintings in the studio with his students that it seems you can find any combination of little ships, waves, and sun.
