Rien ne pese tant que un secret. [Nothing weighs more than a secret.] ~ La Fontaine
The secret being that she has conceived...only her body knows this secret and keeps it so for a while! When she counts backwards she realises that this was the night of nights. The poem doesn't let on either except for its title! The poem only observes and doesn't comment...just sees her and the state of the room for what it is...the new millennium cometh and makes her a lady in waiting.
The poem insists on keeping its mystery....it is not necessary for it to give it up! The explanation lives amongst the backstory with the little afterglow of knowing if one wants a little more insight into what was going on....although one does not have to know that!
