The sudden illumination, the bursts of the floods of lava, and the earthquake, which we have already described, chanced when Sallust and his party had just gained the direct path leading from the city to the port; and here they were arrested by an immense crowd, more than half the population of the city.  They spread along the field without the walls, thousands upon thousands, uncertain whither to fly.  The sea had retired far from the shore; and they who had fled to it had been so terrified by the agitation and preternatural shrinking of the element, the gasping forms of the uncouth sea things which the waves had left upon the sand, and by the sound of the huge stones cast from the mountain into the deep, that they had returned again to the land, as presenting the less frightful aspect of the two.  Thus the two streams of human beings, the one seaward, the other from the sea, had met together, feeling a sad comfort in numbers; arrested in despair and doubt.

‘The world is to be destroyed by fire,’ said an old man in long loose robes, a philosopher of the Stoic school:  ’Stoic and Epicurean wisdom have alike agreed in this prediction:  and the hour is come!’

‘Yea; the hour is come!’ cried a loud voice, solemn, but not fearful.

Those around turned in dismay.  The voice came from above them.  It was the voice of Olinthus, who, surrounded by his Christian friends, stood upon an abrupt eminence on which the old Greek colonists had raised a temple to Apollo, now timeworn and half in ruin.

As he spoke there came that sudden illumination which had heralded the death of Arbaces, and glowing over that mighty multitude, awed, crouching, breathless—­never on earth had the faces of men seemed so haggard!—­never had meeting of mortal beings been so stamped with the horror and sublimity of dread!—­never till the last trumpet sounds, shall such meeting be seen again!  And above those the form of Olinthus, with outstretched arm and prophet brow, girt with the living fires.  And the crowd knew the face of him they had doomed to the fangs of the beast—­then their victim—­now their warner! and through the stillness again came his ominous voice: 

‘The hour is come!’

The Christians repeated the cry.  It was caught up—­it was echoed from side to side—­woman and man, childhood and old age, repeated, not aloud, but in a smothered and dreary murmur: 

‘The hour is come!’

At that moment, a wild yell burst through the air—­and, thinking only of escape, whither it knew not, the terrible tiger of the desert leaped amongst the throng, and hurried through its parted streams.  And so came the earthquake—­and so darkness once more fell over the earth!

And now new fugitives arrived.  Grasping the treasures no longer destined for their lord, the slaves of Arbaces joined the throng.  One only of all their torches yet flickered on.  It was borne by Sosia; and its light falling on the face of Nydia, he recognized the Thessalian.
