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

This image depicts a trio of figures engaged in a winter activity called "skiing," which would be unfamiliar to someone from the 15th century. They are traversing a snowy landscape with elongated wooden planks attached to their boots, which allow them to glide over the snow. Each figure holds a long staff in each hand, which they use to help balance and propel themselves forward. They wear protective coverings on their heads and eyes, and garments that fit closely to the body to maintain warmth and allow movement. In the background, tall, pointed trees common in colder climes are visible, further indicating that this activity takes place during the winter season. Along the side of the snowy path, small markers are visible, likely used to guide the path of the skiers.
