CHAPTER XL: Reign Of Justinian .-- Part V.
If we extend our view from the tropic to the mouth of the Tanais, we may observe, on one hand, the precautions of Justinian to curb the savages of Aethiopia, [125] and on the other, the long walls which he constructed in Crimaea for the protection of his friendly Goths, a colony of three thousand shepherds and warriors.

[126] From that peninsula to Trebizond, the eastern curve of the Euxine was secured by forts, by alliance, or by religion; and the possession of Lazica, the Colchos of ancient, the Mingrelia of modern, geography, soon became the object of an important war.

Trebizond, in after-times the seat of a romantic empire, was indebted to the liberality of Justinian for a church, an aqueduct, and a castle, whose ditches are hewn in the solid rock.

From that maritime city, frontier line of five hundred miles may be drawn to the fortress of Circesium, the last Roman station on the Euphrates.

[127] Above Trebizond immediately, and five days' journey to the south, the country rises into dark forests and craggy mountains, as savage though not so lofty as the Alps and the Pyrenees.
