Norman Palace Chapel

For mere tourists, the main reason to visit the Norman Palace is its 12th century chapel, every square millimeter of which is adorned in incredible mosaic. The style and stories are quite similar to the somewhat younger Monreale, but, since it's a royal chapel and not an abbey church, thus smaller, the mosaics are much closer. And they are better lit and were cleaned relatively recently.

Thus; altar, dome...

Pantokrator pose again; turns out, upon further "research," that 
this term is best associated with the Almighty him/herself, and 
not with JHC; the authority for this is the the good old Book of 
Revelation, wherein God and Christ are generally used 
interchangeably, but Pantokrator used strictly with God; just 
another useful item of information, from the all-knowing and
self-correcting Wikipedia

Panning around the incredible walls

Familiar Old Testament scenes

Ditto

Ditto again

Plus some more New Testament scenes, here, the Baptism of St. Paul

The meeting of Saints Paul and Peter

And, the show-stealer for me, Peter and Paul disputing with Simon Magi, before 
Nero; if you want to catch a bit of the flavor of early Church "history,"  look up 
Simon  Magi; BONUS QUESTION: what is the important (if somewhat obscure)

connection between this scene and City Slickers?
