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

This image depicts a curious scene of sport or game, unrecognizable by the standards of your time. There are three women dressed in close-fitting attire, all involved in an activity upon a slick, smooth surface bordered by wooden barriers. They are engaged with sliding large, rounded stones towards a marked target area.Each woman wields a long, broom-like tool, which they appear to use for guiding or adjusting the path of these stones as they glide across the surface. One of the women is energetically sweeping ahead of a stone, possibly to influence its speed or trajectory, while another bends in a starting position, releasing a stone towards the target.The setting for this activity is enclosed, possibly to protect the surface or to set boundaries for this unusual and strategic pursuit. Such games are beyond the imagining in the 15th century, being more akin to what you might believe to be the antics of folks in a wintry folk tale or fantasy, where smooth ice and clever tactics combine in an endeavor of skill and grace.
