Microfiction challenge #13: Woman in the sun

I relented. Today’s prompt was going to be something in keeping with yesterday’s mood—funereal. I’ll keep that for another time. This painting, by Caspar David Friedrich, is a pretty strange one so it will do very nicely for a prompt. Who is this woman in her gown and hairdo that make me think of a fantasy queen? What is she doing? Invoking the sun or some other deity? Grieving for someone, something? Is it dawn or sunset?

The theme words are:

Dawn sunset worship magic power regal
