Narcissus - Caravaggio
I think you had told about the myth of the work of art really well and after reading your analysis I looked at the painting in a whole new way. I also think the painting itself may haven't any dividual message but its myth is some kind of message. Maybe it tells at least about people's self-love. The artist may have included in the painting a teaching for people like Narcissus. On the other hand I think Narcissus in a way did nothing wrong even he rejected all romantic advances. I think the painting is simple but it gets a lot of thought if you know the backgrounds of the painting.
