If I may muse for a bit, volvelles are a fascinating way to arrange a table. A pivoting table? Wheels within wheels. If you stack two logarithmic number lines, you have a slide rule. Clocks are volvelles with arms instead of discs. There are not only volvelles for calculation, but volvelles for remembering state capitals and volvelles for learning grammar rules.
So many departures on a thing which turns upon itself. You might even wind up with Willie, Freddie, and Flaco.
Come back, come back to your arms again. I’ll come back to where you are.
