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

The image presents a simple depiction of a landscape, likely intended to represent a rugged mountainous region. Each form resembles the peaks of mountains, heavily stylized into jagged, sharp lines that converge at various angles to suggest elevation and structure. Below these mountain forms, there are also more triangular shapes spaced apart, which may symbolize smaller hills or distant mountains. Furthermore, there are some horizontal lines at the bottom, possibly indicating a flat plane like a valley or a plain in front of these mountains.The entire artwork is done in black outlines without any form of shading or color, which gives it a bare and abstract aesthetic, reflecting perhaps only the essential features of a mountainous terrain. This style might seem peculiar yet intriguing to a viewer from the 15th century, accustomed to more detailed and naturalistic forms of art.
