Near this mausoleum is the magnificent Basilica of St. Vitale, built in the reign of Justinian, and consecrated in 547, I was interested to see it because it was erected in confessed imitation of St. Sophia at Constantinople, is in the octagonal form, and has all the accessories of Eastern splendor, according to the architectural authorities. Its effect is really rich and splendid; and it rather dazzled us with its maze of pillars, its upper and lower columns, its galleries, complicated capitals, arches on arches, and Byzantine intricacies. To the student of the very early ecclesiastical art, it must be an object of more interest than even of wonder. But what I cared most to see were the mosaics in the choir, executed in the time of Justinian, and as fresh and beautiful as on the day they were made. The mosaics and the exquisite arabesques on the roof of the choir, taken together, are certainly unequaled by any other early church decoration I have seen; and they are as interesting as they are beautiful. Any description of them is impossible; but mention may be made of two characteristic groups, remarkable for execution, and having yet a deeper interest. In one compartment of the tribune is the figure of the Emperor Justinian, holding a vase with consecrated offerings, and surrounded by courtiers and soldiers. Opposite is the figure of the Empress Theodora, holding a similar vase, and attended by ladies of her court. There is a refinement and an elegance about the empress, a grace and sweet dignity, that is fascinating. This is royalty,-- stately and cold perhaps: even the mouth may be a little cruel, I begin to perceive, as I think of her; but she wears the purple by divine right. I have not seen on any walls any figure walking out of history so captivating as this lady, who would seem to have been worthy of apotheosis in a Christian edifice. Can there be any doubt that this lovely woman was orthodox? She, also, has a story, which you doubtless have been recalling as you read. Is it worth while to repeat even its outlines? This charming regal woman was the daughter of the keeper of the bears in the circus at Constantinople; and she early went upon the stage as a pantomimist and buffoon. She was beautiful, with regular features, a little pale, but with a tinge of natural color, vivacious eyes, and an easy motion that displayed to advantage the graces of her small but elegant figure. I can see all that in the mosaic. But she sold her charms to whoever cared to buy them in Constantinople; she led a life of dissipation that cannot be even hinted at in these days; she went off to Egypt as the concubine of a general; was deserted, and destitute even to misery in Cairo; wandered about a vagabond in many Eastern cities, and won the reputation everywhere of the most beautiful courtesan of her time; reappeared in Constantinople; and, having, it is said, a vision of her future, suddenly took to a pretension of virtue and plain sewing;
