We watched the enceinte of the city of Byzas grow, saw how the walls he built to landward could no longer contain the increasing population. The walls that Byzas built have vanished, and those of Constantine the Great have served their purpose, and were dismantled, so that to Theodosius II was left the task of giving to the city its widest limits. Historians of the time draw a pleasant picture of the scene when these walls were erected. The different factions all combined to help, and inscriptions, still to be seen, testify to this fact. All citizens were called upon to assist, so without waste of time these walls arose. Misfortune visited them shortly after their completion, when an earthquake overthrew a great portion of the work, including fifty-seven towers. At an inopportune moment too, for the arms of Theodosius had suffered defeat by Attila in three successive engagements, and “The Scourge of God,” as he was pleased to call himself, having ravaged the provinces of Macedonia and Thrace with fire and sword, was drawing very near to Constantinople. But two determined men—Constantine, Prætorian Prefect of the East, and Marcellius Comes—called upon the patriotism of the populace, and in less than three months the damaged walls had been restored and even strengthened by their united efforts.

An imposing prospect these walls still offer even in their present state; how much more formidable must they have appeared when all one hundred and ninety-two towers stood firm and unshaken and the walls between had not been broken by an enemy’s artillery or dismantled by the tooth of time! Their construction was a marvel of devotion, their plan the work of genius, for of its kind no defences better calculated to protect a city were ever devised by human ingenuity. Let us move to the very edge of the road, where there is a slightly raised and extremely irregular footpath, and take a general and comprehensive glance at the walls of Theodosius. At our feet the counterscarp which stayed the earth on the enemy’s side from filling up the moat. There comes the moat over sixty feet in width. The depth when still in use is not known to us, but we know from our visit to the Golden Gate that it must have been considerable.

The wall we see on the further side of the moat, taking the enemy’s point of view, is the scarp. Some of its battlements remain; they served to cover the movements of troops on the terrace between the scarp and the wall. This outer wall rises to about ten feet and tapers from a base of about six feet in thickness to two feet at the summit. From the remains of this wall we can gather that it contained a long series of vaulted chambers which offered shelter to the troops engaged in the defence, and there are loopholes facing west, through which their fire was directed. Small towers, some round, others square, about thirty-five feet high, still further strengthened the position. But the main defence lay in the inner wall, separated from the outer one by a broad terrace of some fifty feet, which served as a parade-ground for the troops that garrisoned the chambers of the outer wall, when the city was invested by an enemy. This imposing mass of fortifications stands on a higher level than the others, and here the main strength of the defence was stationed. A chain of mighty towers composed it, and they are linked together by stout walls known as curtains to the expert. These towers, most of which are square, stand about one hundred and seventy feet apart, and rose, when in their completed state, to a height of sixty feet, standing out some twenty feet from the curtain. Each tower contained, as a rule, two chambers, was built of carefully cut stone and vaulted inside with brick. Many a broken tower shows on the outside some mark or inscription dating back to the distant days of the glory of old Byzantium. On the city side of the inner wall may still be seen traces of stone steps that led up to the summit, whence other flights of steps led under cover of battlements to the roof of each tower.

For ten centuries these walls defied all onslaughts of an enemy; the battle-cry of many strange races, some whose day is done, others who stand high in the history of civilization to-day, was answered by shouts of defiance from the defenders of the city. So let us cross over the moat and look into one of those huge towers, which with their attendant curtains gave the Eastern capital its immunity from invasion for so many ages. Though appearing to form one solid mass, they are in reality built separately, so as to allow for the different rate of sinking between buildings of different weight.

We may enter one of these broken towers from the



inner terrace, by a gap in the strong stonework, caused probably by an earthquake. This opening takes us to a place half-way between the floor and ceiling of the lower chamber. The vaulting that supported the upper floor has fallen in, but we can trace it in the brickwork that here, as elsewhere amid these walls, recall in shape and colour the remains of the defences of Imperial Rome. And yet another likeness strikes us in the courses of brick, laid at intervals in the construction of walls and towers, which served to bind the mass of masonry yet more firmly. This lower chamber, all dismantled now, and overgrown with weeds, may in times of peace have served a peaceful purpose. Access to it was from inside the walls, and the proprietor of the land on which it stood was permitted to use it for what purposes he chose. But when the fire signals that flared on the tops of convenient heights gave notice of an enemy’s approach these vaults would ring with the sound of armour and the epithets wherewith soldiers of all ages are supposed to garnish their remarks.
