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

What you see depicted here is a simple, line-drawn scene that might remind one of a tapestry. At the center is a series of stepped shelves of varying widths, akin to the steps one might find in a garden or near a village fountain. Upon these shelves, you observe four birds, resembling ducks, each individually placed on its own tier.The surroundings of these shelves are adorned with what look like tall grasses or reeds, common in marshy or lakeside areas. Additionally, there are abstract shapes floating above the birds. These could be interpreted as clouds, leaves, or perhaps even symbolic representations, common in artwork of your time for depicting the natural world and its elements.
