By and by the Church required enlargement, and it was then cruci-formed by the addition of transepts right and left. Still later, a Chapel was erected specially for the relics and the All Holy Banner. This was contiguous to the Church, and besides being fireproof, it covered a spring of pure water, afterwards essential in many splendid ceremonies civil as well as religious. The Chamber of Relics was prohibited to all but the Basileus. He alone could enter it. By great favor, the Prince of India was once permitted to look into the room, and he remembered it large and dimly lighted, its shadows alive, however, with the glitter of silver and gold in every conceivable form, offered there as the Wise Men laid their gifts before the Child in the Cave of the Nativity.

Again and again the Church was burned, yet the Chapel escaped. It seemed an object of divine protection. The sea might deliver tempests against the Seven Hills, earthquakes shake the walls down and crack the hanging dome of St. Sophia, cinders whiten paths from the porphyry column over by the Hippodrome to the upper terrace of Blacherne; yet the Chapel escaped—yet the holy fountain in its crypt flowed on purer growing as the centuries passed.

The Prince, whose memories we are but weaving into words, did not wonder at the increase of veneration attaching to the Chapel and its precious deposits—manuscripts, books, bones, flags, things personal to the Apostles, the Saints, the Son and His Mother, parings of their nails, locks of their hair, spikes and splinters of the Cross itself—he did not wonder at it, or smile, for he knew there is a devotional side to every man which wickedness may blur but cannot obliterate. He himself was going about the world convinced that the temple of Solomon was the House of God.

The guards sprawling on the benches kept staring at him; one of them let his axe fall without so much as attracting the Prince's attention. His memory, with a hold on him too firm to be disturbed by such trifles, insisted on its resurrectionary work, and returned him to the year 865. Constantinople was again besieged, this time by a horde from the Russian wilderness under the chiefs Dir and Askold. They had passed the upper sea in hundreds of boats, and disembarking on the European shore, marched down the Bosphorus, leaving all behind them desolate. Photius was then Patriarch. When the fleet was descried from the walls, he prevailed on the Emperor to ask the intervention of the Virgin. The Maphorion or Sacred Robe was brought out, and in presence of the people on their knees, the clergy singing the hymn of Pisides, the holy man plunged it into the waves.

A wind arose under which the water in its rocky trough was as water in a shaken bowl. The ships of the invaders sunk each other. Not one survived. Of the men, those who lived came up out of the vortexes praying to be taken to the Church of Blacherne for baptism. This was two hundred years and more after the first deliverance of the city, and yet the Mother was faithful to her chosen!—Constantinople was still the guarded of God!—The Penagia was still the All Holy! Having repulsed the Muscovite invasion, what excuse for his blasphemy would there be left the next to challenge its terrors?

The Prince of India saw the blackened walls of the burned Church, an appealing spectacle which the surrounding trees tried to cover with their foliage, but could not; then he lifted his eyes to the Palace upon the third terrace.

To the hour decay sets in the touches of Time are usually those of an artist who loves his subject, and wishes merely to soften or ennoble its expression. So had he dealt with the Very High Residence.

It began in the low ground down by the Cynegion, and arose with the city wall, which was in fact its southwestern front. Though always spoken of in the singular, like the Bucoleon, it was a collection of palaces, vast, irregular, and declarative of the taste of the different eras they severally memorialized. The spaces between them formed courts and places under cover; yet as the architects had adhered to the idea of a main front toward the northeast, there appeared a certain unity of design in the structures.

This main front, now under the Prince's view, was frequently broken, advancing here, retreating there; one section severely plain and sombre; another relieved by porticos with figured friezes resting on tall columns. The irregularities were pleasing; some of them were stately; and they were all helped not a little by domes and pavilions without which the roof lines would have been monotonous.

Lifting his gaze up the ascent from the low ground, it rested presently on a Tower built boldly upon the Heraclian wall. This was the highest pinnacle of the Palace, first to attract the observer, longest to hold his attention. No courier was required to tell its history to him through whose eyes we are now looking—it was the tower of Isaac Angelus. How clearly its outlines cut the cloudless sky! How strong it seemed up there, as if built by giants! Yet with windows behind balconies, how airy and graceful withal! The other hills of the city, and the populated valleys between the hills, spread out below it, like an unrolled map. The warders of the Bucoleon, or what is now Point Serail, the home-returning mariner shipping oars off Scutari, the captain of the helmeted column entering the Golden Gate down by the Seven Towers, the insolent Genoese on the wharves of Galata, had only to look up, and lo! the perch of Isaac. And when, as often must have happened, the privileged lord himself sat midafternoons on the uppermost balcony of the Tower, how the prospect soothed the fever of his spirit! If he were weary of the city, there was the Marmora, always ready to reiterate the hues of the sky, and in it the Isles of the Princes, their verdurous shades permeated with dreamful welcome to the pleasure-seeker as well as the monk; or if he longed for a further flight, old Asia made haste with enticing invitation to some of the villas strewing its littoral behind the Isles; and yonder, to the eye fainting in the distance, scarce more than a pale blue boundary cloud, the mountain beloved by the gods, whither they were wont to assemble at such times as they wished to learn how it fared with Ilium and the sons of Priam, or to enliven their immortality with loud symposia. A prospect so composed would seem sufficient, if once seen, to make a blind man's darkness perpetually luminous.
