see there two beautiful alabaster columns with
capitals of serpentine with two small columns of verde antico also
with ancient capitals. The screen is Byzantine. The walls are
ornamented with bas-reliefs and paintings, but above all these we see
there a marvellous portrait in mosaic of the emperor Justinian as an
old man, unhappily restored in 1863. The altar is ancient and above it
is a marble coffer with Renaissance ornaments, upheld by four columns
of porphyry, having two Byzantine and two Roman capitals. On the
Epistle side of the altar here is a marble chair--a Roman thing.

From that splendid and well-preserved church we pass to that of the
Spirito Santo. Unhappily this once glorious building has suffered as
much as any church left to us in Ravenna, for it was almost entirely
rebuilt in 1543 when the portico we see was added to it, and in 1627
was restored and adorned, as it was in 1854 and 1896. That it was
founded and built by the Goths and reconciled later for Catholic use
appears in Agnellus' life of the archbishop S. Agnellus, where we read
that of old the Arian Episcopio stood near by, together with a bath
and a _monastero_ of S. Apollinare. What the _monastero_ may have been
we do not know, but the bath was perhaps the Arian baptistery known as
S. Maria in Cosmedin.

The church of the Spirito Santo was not in Arian times known under
that dedication, but was called of S. Theodore. It owes the pleasing
portico it now possesses, as I have said, to the sixteenth century,
but that portico is itself largely constructed of old materials, being
upheld by eight antique columns, of which six are of Greek marble.
These originally supported the baldacchino over the high altar.
Within, the church is divided into three naves by fourteen columns,
thirteen of which are of bigio antico, and the other, the last on the
Epistle side towards the altar, of a rare and curious marble known as
verde sanguigno. The capitals are of Theodoric's time, late Roman
work.

Very little remains in the church that is of any interest to us. In
the sacristy, however, we may see in the present lavabo some fragments
of the ancient ciborio. And in the nave at the western end on the
Gospel side is an ancient sarcophagus of Greek marble which was carved
in the Renaissance and in the seventeenth century became the sepulchre
of one of the Pasolini family. In the first chapel on this side of the
church is the ancient _ambone_ removed from the nave i
