It is buildings such as these that enable us to see what Justinian was to the capital of his Empire. Every year it seemed that new victories and new conversions were increasing the power of the Empire and the Church. While Belisarius reconquered Italy and made the name of the Cæsar again honoured at Rome and Ravenna, ended the cruel rule of the Vandals in Africa and Sicily, crushed the Goths of Spain, and kept the strong Persian prince at bay on the eastern frontier of the empire, Christian missions spread the faith of the orthodox Church to the Caucasus and the Sudan. Again and again did processions of returning warriors pass along the triumphal way, but the Emperor alone entered by the Golden Gate. It was in the Hippodrome that Belisarius celebrated his triumph over the Vandals. It was nigh six hundred years, Procopius thought, since any had had the same. But Belisarius walked with a proud humility from his own house to the Hippodrome, and thence from his own tent to the imperial throne. The rich spoils that were spread out were the treasures of all the years of Vandal conquest, and among them some of the vessels that Titus had brought from the temple at Jerusalem and Generic the Vandal conqueror had taken from Rome. These Justinian gave to churches in the Holy City. As the captives were led up to the imperial throne all eyes were fixed on the Vandal chief, Gelimer, wearing the purple, as in mockery, with his kindred about him, "himself the tallest and most beautiful of the Vandals." As he walked up to the throne he looked up, and uttering no lament for his fallen state, said with the poet's simple feeling, "Vanity of vanities." They stripped him of his robe and made him fall on his face before the Emperor. Beside him knelt his conqueror, and supplicated for his pardon, and the day was crowned by generosity such as the Emperor loved to show and the people to applaud. [Illustration: THE GOLDEN GATE]
