These plays and stories have for their continual theme the passing away of gods and men and cities before the mysterious power which is sometimes called by some great god's name but more often 'Time.' His travellers, who travel by so many rivers and deserts and listen to sounding names none heard before, come back with no tale that does not tell of vague rebellion against that power, and all the beautiful things they have seen get something of their charm from the pathos of fragility. This poet who has imagined colours, ceremonies and incredible processions that never passed before the eyes of Edgar Allen Poe or of De Quincey, and remembered as much fabulous beauty as Sir John Mandeville, has yet never wearied of the most universal of emotions and the one most constantly associated with the sense of beauty; and when we come to examine those astonishments that seemed so alien we find that he has but transfigured with beauty the common sights of the world.
