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

In the image, there is a drawing of a fanciful creature resembling a mouse, adorned with human clothes and engaging in a human activity. The creature stands upright on two blades attached to boots, a sport known today as ice skating, which would be a marvelous spectacle for someone of the 15th century who might be familiar only with basic forms of ice sliding or games. The mouse wears a long coat and a pointed cap with a ball at the end, attire that might remind you of the festive garb from tales or festivals during your time. It glides across what appears to be a frozen stream or pond, an activity indicating both leisure and skill. The entire scene is depicted in a simple, clear outline without color, suggesting it might be a pattern for embroidery or perhaps a template for further artistic embellishment. Such images today are often used to amuse children or to decorate spaces whimsically.
