bonjour,
Following your comment, I made this page about rotations in 3d space.
Could this kind of literature be useful for POV user or no one is
interested or even be annoying ?

It's on my website and in English ;)

The animations "played", but were just black - no images.

Note: Contrary To Bald Eagle, the animations played correctly on my
system (Win11) not black.
I think these kind of simple and clear visual explanations can be very
useful, certainly for starting (POV-Ray) modellers, but also for old
hands who have temporarily lost their way in confusion and need a little
reminder. :-) I am certainly one of those from time to time.
I would suggest that you label the x-, y-, z-axis in the first
animation, and/or add the usual red, green, and blue colours to them.
Well done and keep on!

Sorry for the inconvenience. I've tested with Fitrefox, Chrome and
Safari on Mac and Edge on Windows and it works fine.
I changed the video format from .mov to .mp4
Can you tell me if it's better?

Very Nice. Works perfectly and the colors and lighting are beautiful.
