The New Murrey and Blue blog

I didn’t know what an armillary sphere was until I saw this page and was prompted to look it up at Merriam Webster, where the definition is:-

“ar·mil·la·ry sphere: an old astronomical instrument composed of rings showing the positions of important circles of the celestial sphere”.

Then I realised that such spheres are often seen in gardens, as well as to be hand-held.

You can read about these spheres in general here, but I had no idea they could also be small enough to be collapsible and turned into finger rings, as in the top image above.

And now copies of these novel rings abound at Amazon US and Amazon UK .
