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

The image before you reveals a young maiden performing a type of dance, a courtly gesture of artistic expression still in its nascent form. She is attired in a garb both elegant and minimal, tailored to afford grace and fluidity in movement. The dress flares outward as she executes a poised stance with one leg lifted high and extended backward, embodying a balance and symmetry that is pleasing to the eye. Her arms extend gracefully, and her countenance is focused and serene, evoking a sense of narrative in her motion. This depiction, though simple in form, captures the essence and vitality of dance, a celebration of corporeal skill and beauty that transcends time.
