Artists have long considered mythology part of their aesthetic language. Mermaids are aquatic mythological monsters who embody the dangers of seduction.
The mermaid seen as realism naturalism hybrid, half-human half-fish is an hybrid art figure, was doomed to develop a peculiar hybrid of realism and conceptualism. It's unfair to say that mermaids do not exist, without showing a proof that mermaids do not still exist.
Both natural and abstract in form, mermaids seem to have grown through the screen of the computer, because under sea narrative figuration returns to contemporary painting.
Do mermaids still exist? In the Duchampian tradition, mythological monsters consider the viewer’s interpretation essential to their work of art. A print from copper plate etching is shown, not a whimsical graphic art, but what is a visual metaphor in art.
The goal of Art is to create in a visible form mermaids which did not previously exist.
On the flip side: "The biased coin is the mermaid of probability theory : everybody has heard of it, but it has never been spotted in the flesh" (reference)
