The Bed
A piece of furniture that cannot be moved becomes a test of a life.
This name counts verified appearances. It does not grade the idea. Corpus size and editorial depth are different.

The olive bed is built, rooted, known. Penelope uses it as a question. This motif is not ‘the marital bed’ as a symbol dumped onto any story. It is a specific made thing in a specific poem.
Other traditions will have other objects of shared knowledge. They should keep their own names.
