What is in this image? Describe it as if you were explaining it to someone from the 15th century.

This image depicts a young maid gliding on a frozen pond, her body leaning into a swift, sweeping movement as she propels herself using blades fixed under her shoes. She is garbed in a whimsical attire perhaps suited to ward off the chill of a harsh winter a long-sleeved garb decorated with hearts and a frill at its hem, a cloth tied around her neck fluttering behind her like a banner in the wind, and a striped cap that clings to her head and shadows her brow. Surrounding her are several small circles, likely meant to represent falling snowflakes or the cold air. The entire scene is captured as if by magic on a surface showing but white and the dark lines that form this merry spectacle.
