The conversion of Constantine gave a new vigour to these local reminiscences of the evangelical history. That celebrated ruler wrote to Macarius, bishop of Jerusalem, to cover the tomb of Jesus Christ with a magnificent church; while his mother, the Empress Helena, repaired in person to Palestine, in order to glue a proper efficacy to the zeal which animated the throne, and to assist in searching for the venerable remains of the first age of the gospel. To this illustrious female is ascribed the glory of restoring to religion some of its most valued memorials. Not satisfied with the splendid temple erected at the Holy Sepulchre, she ordered two similar edifices to be reared under her own auspices; one over the manger of the Messiah at Bethlehem, and the other on the Mount of Olives, to commemorate his ascension into heaven. Chapels, altars, and houses of prayer gradually marked all the places consecrated by the acts of the Son of Man; the oral traditions were forthwith committed to writing, and thereby secured for ever from the treachery of individual recollection.[4] These considerations gave great probability to the conjectures of those pious persons who, in the fourth century of our era, assisted the mother of Constantine in fixing the locality of holy scenes. From that period down to the present day, the devotion of the Christian and the avarice of the Mohammedan have sufficiently secured the remembrance both of the places and of the events with which they are associated.
