OK, this one is a long shot. I remember almost nothing of this story, not even if it is Fantasy or science fiction. Only that is was rather short story, certainly not a novel. And that I read it in the 60’s.
The main character is looking for a strange object (Magical? Or man-made through advanced science?) the name of which I forgot, in which one can see the entire world. Even stranger, it might maybe even encompass the entire world, if I remember properly.
In fact, I was reminded of this story by Escher’s “Hand with reflecting sphere” one can find for instance here at this link or pictured below. But it has no direct link with the story, just as a jog to my memory.
In a very emotional scene, he finds this object (I am not even sure it is really spherical) while repeating as if a mantra the name of a woman. I think the name is in three parts, but (first name, middle name and last name), or (first name, maiden name, husband’s last name), I don’t remember. That’s it. Any ideas?
