I should say why I think spinning wheels predate wagon wheels. If you spin thread, you need a way to keep it neat. Rolling it around a stick would do it.
Spinning wheels (operated by foot, or by turning a wheel) are very recent developments--roughtly around medieval/Renaissance. Until that time, all thread was spun on a spindle, an item of engineering so simple that you can manage it with a stick stuck into a potato. Even a small item of clothing was very labor-intensive--where we get our term, "heirloom."

Been reading a little of Basque lately because of the ETA--such a lot of Z's and K's! Has a very Greco affect.
And I'm always interested in Finnish, since that's what Tolkein used as a model for Elvish.
