Nice, I like it. Short and to the point as is true with the old Greek mythology. The only thing I would modestly suggest is not to use modern day catch phrases like 'by a mile'. Perhaps try replacing it with something like "To Ares, Callisto's beauty was as dark as the night(since she is dark-haired and not golden as the sun), cloaking and covering that of Aphrodite's." Hope I helped a little :)

It's a good myth. I never known that Callisto was the most beautiful woman in the world before Helen of Troy. pleae read my two stories called Cassandra's Refusal and Ariadne and Theseus. They are both short and they are love stories. Please read them. I would appreciate it.

It does go along with the typical pattern of myths. If that was the idea, you accomplished it. This reminds me a little of the Sibyl and Apollo. Your last sentence is a bit confusing, though. "Now, no one will ever forsake the wrath of Aphrodite." I think you mean something more along the lines of "escape." To forsake is the same as to abandon, and no one would willingly stay in Aphrodite's wrath.
