The image is a black and white illustration of a stone labyrinth located on Wier Island in the Gulf of Finland. The labyrinth is depicted as a spiral pattern formed by a series of small, oval-shaped stones. The spiral winds inward towards a central point, creating a complex and winding path. The stones are closely packed together, forming a continuous line that defines the labyrinth's structure. The background is a light beige color, providing contrast to the dark black lines of the labyrinth. Below the image, there is a caption that reads 'FIG. 124. - Stone Labyrinth on Wier Island, Gulf of Finland. (von Baer)'.
