The association of fountains at its base with this obelisk seems at first sight as incongruous as the crowning of its apex with a metal cross, for the Christian emblem can never alter the nature of the pagan monument. There is no natural harmony in the association, for there are no fountains or streams of running water in the desert. The obelisk belongs essentially to the dry and parched east; the fountain is the birth of the happier west, bright with the sparkle and musical with the sound of many waters. The obelisk relieves the monotony of immeasurable plains over which a sky of serene unstained blue arches itself in infinite altitude, the image of eternal purity, and the sun rises day after day with the same unsullied brilliance, and sets with the same unmitigable glory. The fountain, on the other hand, is the child of lands whose mountains kiss the clouds and gleam with the purity of everlasting snows, and where each day brings out new beauties, and each season reveals a fresh and ever-varying charm. But although there is no geographical reason why these two objects should be associated, there is a poetical fitness. The obelisk is the symbol of the perpetual past, holding in its changeless unity, as on its carved sides, the memories of former ages; the fountain is the symbol of the perpetual present, ever changing, ever new. The one speaks to us of a petrified old age; the other of an immortal youth. And thus it is in life, each passing moment flowing on with all its changes beside the stern, hard, enduring monument of the irrevocable past on which what is written is changelessly written. How different too are the bright sparkling fountains that leap with ever-varying beauty at the foot of the Flaminian obelisk now, from the dull, sleepy monotonous river that, like a Lethe flood, flowed past it in the old days at Heliopolis! Are they not both symbolical of the new and the old world, of the Christian faith, with its progressive thought and varied expanding life, and the stagnant pagan creed, which impressed the soul with the sense of human helplessness in the face of an unchangeable iron order alike of nature and of society?
