The enthusiasm which inspired the troops, and perhaps the emperor himself, had sharpened their swords while it satisfied their conscience. They marched to battle with the full assurance, that the same God, who had formerly opened a passage to the Israelites through the waters of Jordan, and had thrown down the walls of Jericho at the sound of the trumpets of Joshua, would display his visible majesty and power in the victory of Constantine. The evidence of ecclesiastical history is prepared to affirm, that their expectations were justified by the conspicuous miracle to which the conversion of the first Christian emperor has been almost unanimously ascribed. The real or imaginary cause of so important an event, deserves and demands the attention of posterity; and I shall endeavor to form a just estimate of the famous vision of Constantine, by a distinct consideration of the _standard_, the _dream_, and the _celestial sign;_ by separating the historical, the natural, and the marvellous parts of this extraordinary story, which, in the composition of a specious argument, have been artfully confounded in one splendid and brittle mass. I. An instrument of the tortures which were inflicted only on slaves and strangers, became on object of horror in the eyes of a Roman citizen; and the ideas of guilt, of pain, and of ignominy, were closely united with the idea of the cross. 29 The piety, rather than the humanity, of Constantine soon abolished in his dominions the punishment which the Savior of mankind had condescended to suffer; 30 but the emperor had already learned to despise the prejudices of his education, and of his people, before he could erect in the midst of Rome his own statue, bearing a cross in its right hand; with an inscription which referred the victory of his arms, and the deliverance of Rome, to the virtue of that salutary sign, the true symbol of force and courage. 31 The same symbol sanctified the arms of the soldiers of Constantine; the cross glittered on their helmet, was engraved on their shields, was interwoven into their banners; and the consecrated emblems which adorned the person of the emperor himself, were distinguished only by richer materials and more exquisite workmanship. 32 But the principal standard which displayed the triumph of the cross was styled the Labarum, 33 an obscure, though celebrated name, which has been vainly derived from almost all the languages of the world. It is described 34 as a long pike intersected by a transversal beam. The silken veil, which hung down from the beam, was curiously inwrought with the images of the reigning monarch and his children. The summit of the pike supported a crown of gold which enclosed the mysterious monogram, at once expressive of the figure of the cross, and the initial letters, of the name of Christ. 35 The safety of the labarum was intrusted to fifty guards, of approved valor and fidelity; their station was marked by
