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 in the sixteenth century, and in the second are two columns of pavonazzetto marble. Something better is to be had in the utterly desolate baptistery close by known as S. Maria in Cosmedin. This was originally, as we may think, the ancient bath of which Agnellus speaks, and it was converted into a baptistery by the Arians, and later consecrated for Catholic uses under the title of S. Maria in Cosmedin and used as an oratory. It is an octagonal building whose walls support a cupola which is covered with mosaics in circles like that of the original baptistery of the city. In the midst we see Christ almost a youth standing naked in Jordan immersed to his waist. Upon His left, S. John stands upon a rock, his staff in his left hand, while his right rests upon the head of Our Lord. Opposite to him sits enthroned the old god of Jordan, a reed in his hand, listening, perhaps, to the words of the Father: "This is my beloved Son in whom I am well pleased." Over Christ's head the Dove is displayed in the golden heaven.
