I have made many small decorative boxes of this model boxes before, whether or not belonging to a particular set like Eye Lash, “F” or “M”. All painted abstract because they were expressing a broader subject. In this case I wanted to be more specific. Because of the length of the legs underneath the box I had the association with a spider.: small body and long legs.
I assume that one of the best known names of a spider in the world is that of the Black Widow. So this object had to become expressing the image of what is known a dangerous spider, at least for her lovers. If she gets the chance she eats the male after the copulation. It seems cruel, but it’s nature that tells her to do her utmost to provide offspring. And the “father” of the offspring is also nutritious food who can help her accomplishing her task. So maybe this adjusts your notion about the Black Widow a little bit of being the spider just sitting in her cobweb waiting for food and kill her lovers.
