The Love of Helen and Paris
1788
by Jacques-Louis David
While the story does not hold up for long as a love story: Helen is married to Menelaus, whom she chosen as a husband so there is no prospect that she was forced into the union, and runs off with the Trojan prince. When Paris dies, instead of returning home, she marries his brother: and then promptly betrays him to Menelaus, who after all those shenanigans was quite happy to take his flighty bride home, where upon they settled down and lived happily, or so it is assumed, ever after! Perhaps the real love story is there after all...
