Ravenna/Arian Baptistery

Exterior of building, the base of which is now far below current ground level.

Dome mosaic of baptism of Christ. From left to right: personification of River Jordan; Christ of beardless type (with dove of Holy Spirit); John the Baptist. Ringed by procession of Apostles.

Same, but closer.

It is interesting to compare the scene on this dome with that on the dome of the Orthodox, or Neonian, Baptistery, which has many similiarities but is overall a much more complex composition. But for some reason I forgot to take pictures in there. Maybe I can find a few online at a later time to put up here for comparison.
