As I mentioned, the plate is exactly 13" wide. Friday the 13th has a connection to the Knights Templar in France, link below.
Notice the roses leading up to the vessel on the right side of the plate. The vessel is marked with vertical and twin meridian lines. The monk figure is depicted in an unflattering light. The Knights Templar were warrior-monks.
If you carefully examine the female figure, you might draw some strange conclusions. For one thing, what is 'she' wearing on her head? It reminds me of something else. What is the white object the monk is holding under his arm? Does the 'female' figure look pregnant to you? What secret is she telling the monk? Why are his toes pointed in the air?
This plate is a mystery wrapped in an enigma -- made in France. If anyone has ever seen one like it, or any painting it might be based on, please let me know.
