SPEAKER 1: We're in the church of Sant'Apollinare in Classe
just outside of Ravenna.
This was once the port for the Roman Empire
in the early first century.
SPEAKER 2: Right.
There had once been a large lagoon
in between the two towns.
That's long gone.
This was actually the site of an ancient Roman cemetery.
And there is every possibility that the first bishop
of Ravenna, Saint Apollinaris, was actually
buried here on this site.
SPEAKER 1: And we see Saint Apollinaris
right here in the center of the apse.
But before we get to that, let's talk
about the church for a second.
We're in a basilica.
And like so many churches in Ravenna,
it's been through many phases.
And just like Sant'Apollinare in Nuovo,
there would have been mosaics all along the nave,
but those are gone.
SPEAKER 2: What we do have is an extraordinary apse mosaic.
It's huge.
SPEAKER 1: Let's start with the archway around the apse.
SPEAKER 2: That's known as the triumphal arch.
SPEAKER 1: And in the top center,
we see a bearded image of God holding a book,
and on either side of him the symbols of the four
Evangelists.
SPEAKER 2: Right.
John is an eagle.
Matthew is the man.
Mark is the lion.
And Luke is the ox.
SPEAKER 1: And they're in a sky filled
with blue and red clouds.
Below them, we see on the left the city of Jerusalem,
on the right Bethlehem.
And from those two very symbolically represented
cities, we see lambs emerging.
SPEAKER 2: Walking up a mountain,
up towards the clouds, up towards Heaven.
SPEAKER 1: So clearly, a purely symbolic representation,
and that continues in the apse mosaic itself.
SPEAKER 2: Largest and most central is a gold cross.
In the center of the cross you can
see a small bust of Jesus Christ.
Surrounding it is a blue field with 99 gold stars.
SPEAKER 1: On either edge of the short arm of the cross
we see the Greek letters alpha and omega,
the idea that Christ is the beginning
and the end, that Christ is all things.
So what we have symbolically represented here
is the story we call the Transfiguration, the moment
when Christ revealed his divine nature to three
of his apostles, Peter, James, and John.
And they're shown here as sheep in a field.
Christ is symbolically represented as the cross.
SPEAKER 2: On either side, we do see two human figures,
half-length representations.
One is Moses, and one is Elijah.
SPEAKER 1: And in the story of the Transfiguration,
when Christ revealed his divine nature
and was filled with white light, Moses and Elijah
appeared with him.
And God the Father spoke and said,
"This is my son whom I love, with whom I am well pleased.
Listen to him."
And so this is the moment of divine revelation,
this appearance of Christ the man as God.
SPEAKER 2: It's so easy to imagine
a sixth-century worshipper sitting here,
understanding that this is a sort
of extraordinary opportunity to have
these sacred truths revealed to them as they sit before it.
SPEAKER 1: The figures of Moses and Elijah in a golden sky
in the realm of the eternal, below Sant'Apollinare in a more
earthly realm, but one represented very schematically
and decoratively.
SPEAKER 2: And of course the sheep are wonderful,
especially down at the bottom.
There are 12 of them, and it's clearly
the reference to the apostles.
SPEAKER 1: And Sant'Apollinare himself stands frontal.
We can see his name written on either side of him,
just in case we're going to forget or be confused.
SPEAKER 2: That's right.
We can't do that.
SPEAKER 1: And he's got his arms raised
in prayer, which is actually a position we often
see in early Christian imagery.
SPEAKER 2: So in these churches in Ravenna,
we see here an apse.
In another church, the apse might be missing.
But we have the mosaics on the walls of the nave,
and we can begin to fit together what these churches would have
looked like when they were new in the fifth and sixth century.
