what does mean this picture's angels?

Hi Februs,

You can read about angels moving the planets (celestial spheres to be exact) for example here:

As you can see on the included picture sometimes angels use cranks for that, they probably have too weak raw muscle power to do it by bare hands


Heavenly spheres is another crazy ancient idea. Medieval people generally didn't believe that universe could be mostly empty, they didn't accept the existence
of vacuum/nothing. Such approach was called horror vacui (fear of vacuum/emptiness).

So you had these invisible spheres which were yet made of some substance (often called ether) and planets set firmly into this spheres. When an angel moved
the sphere, the planet moved with it

Movement of these spheres was believed to create some very beautiful, angelic music. Unfortunately people became too barbaric and lost the ability to hear it.

Hope it helps you!
