Narsocsis and Eco

I can infer that Eco is the woman in the picture. I can infer this because "she loved him and followed him" meaning Narcosis, and in the picture she is staring lovingly at the man, who is Narcosis. I can also use common cense, since the picture is called Narcosis and Eco, and I know that narcosis is the other person in the picture, I can gather that this is Eco.
