What can it be? Why have they descended into this dark hole, these little ones, who howl in the midst of the smoke, held by these phantoms in mourning? Had we entered it unawares we might have thought it a den of wicked sorcery, an underground cavern for the black mass. But no. It is the crypt of the basilica of St. Sergius during the Coptic mass of Easter morning. And when, after the first surprise, we examine these phantoms, we find that, for the most part, they are young mothers, with the refined and gentle faces of Madonnas, who hold the plaintive little ones beneath their black veils and seek to comfort them. And the sorcerer, who plays the cymbals, is a kind old priest, or sacristan, who smiles paternally. If he makes all this noise, in a rhythm which in itself is full of joy, it is to mark the gladness of Easter morn, to celebrate the resurrection of Christ--and a little, too, no doubt, to distract the little ones, some of whom are woefully put out. But their mammas do not prolong the proof--a mere momentary visit to this venerable place, which is to bring them happiness, and they carry their babes away: and others are led in by the dark, narrow staircase, so low that one cannot stand upright in it. And thus the crypt is not emptied. And meanwhile mass is being said in the church overhead. But what a number of people, of black veils, are in this hovel, where the air can scarcely be breathed, and where the barbarous music, mingled with wailings and cries, deafens you! And what an air of antiquity marks all things here! The defaced walls, the low roof that one can easily touch, the granite pillars which sustain the shapeless arches are all blackened by the smoke of the wax candles, and scarred and worn by the friction of human hands. At the end of the crypt there is a very sacred recess round which a crowd presses: a coarse niche, a little larger than those cut in the wall to receive the tapers, a niche which covers the ancient stone on which, according to tradition, the Virgin Mary rested, with the child Jesus, in the course of the flight into Egypt. This holy stone is sadly worn to-day and polished smooth by the touch of many pious hands, and the Byzantine cross which once was carved on it is almost effaced. But even if the Virgin had never rested there, the humble crypt of St. Sergius would remain no less one of the oldest Christian sanctuaries in the world. And the Copts who still assemble there with veneration have preceded by many years the greater part of our Western nations in the religion of the Bible.
