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

The image depicts a pattern that might be likened to a tapestry or a stained glass design one would find in a grand cathedral or noble house. It features a number of bell-shaped forms, likely flowers, surrounded by blade-like leaves. These floral shapes are evenly arranged among swaying leaves, creating a rhythmic and continuous natural design that could be reminiscent of the motifs in the margins of illuminated manuscripts or the carvings in woodwork of your time. The image is purely in black and white, without color, which accentuates the shapes and the contrast between the figures and their background.
