The image shows a grid of ancient-looking symbols or characters. They appear to be a form of runic or archaic writing. The symbols are primarily composed of straight lines and angles, resembling geometric shapes and simplified representations of letters or pictograms. They are arranged in four rows, with six symbols in each row. The style is reminiscent of medieval or early historical inscriptions. The symbols are drawn in black ink on a light-colored background, and the lines are somewhat rough and uneven, suggesting they were hand-drawn. At the bottom of the image, there is a caption that reads 'Fig. 7.'
