As I recall it, it's about an (amnesiac?) low-tech man that meets and avoids the destroyer-wheel and tries to figure out what his world is all about. The Wheel(s?) rolls leisurely around the planet in some kind of random search and is seen only periodically. I don't remember how the Wheel destroys, but I THINK a beam lances out and fries nearby stuff? Low-tech people are sparsely dotted here and there, living by subsistence agricultur and hoping to avoid being noticed by the Wheel. At some point, the wandering wondering man comes upon a woman with a smallholding and stays with her for a while. Memory grows dim after that.
That's all the detail I have. This PRINTED work must be at least 40 ears old. Thanks.
I'm not making this easy, am I? It's probably going to take another old geezer like myself to identify this one. If you know a likely expert, pass on this query. I want a title and author. Please notice the parameters: old and printed, printed and old. Thanks.
