Imagine the poles of the celestial equator and the ecliptic as two cogs in a huge steam engine, the former fixed and the other revolving around it 3 minutes 56 seconds more quickly than once a day. Imagine a great piston attached to a crank on the ecliptic wheel axle driven in reciprocal motion on a track fixed to the horizon.

That is the visible sector of the Zodiac.

And your chronotypes for the week:

and this one.
