'Niger,' said he, turning suddenly, as he had now threaded the crowd; 'we have often quarrelled; we are not matched against each other, but one of us, at least, may reasonably expect to fall--give us thy hand.' 'Most readily,' said Sosia, extending his palm. 'Ha! what fool is this? Why, I thought Niger was at my heels!' 'I forgive the mistake,' replied Sosia, condescendingly: 'don't mention it; the error was easy--I and Niger are somewhat of the same build.' 'Ha! ha! that is excellent! Niger would have slit thy throat had he heard thee!' 'You gentlemen of the arena have a most disagreeable mode of talking,' said Sosia; 'let us change the conversation.' 'Vah! vah!' said Lydon, impatiently; 'I am in no humor to converse with thee!' 'Why, truly,' returned the slave, 'you must have serious thoughts enough to occupy your mind: to-morrow is, I think, your first essay in the arena. Well, I am sure you will die bravely!' 'May thy words fall on thine own head!' said Lydon, superstitiously, for he by no means liked the blessing of Sosia. 'Die! No--I trust my hour is not yet come.' 'He who plays at dice with death must expect the dog's throw,' replied Sosia, maliciously. 'But you are a strong fellow, and I wish you all imaginable luck; and so, vale!' With that the slave turned on his heel, and took his way homeward. 'I trust the rogue's words are not ominous,' said Lydon, musingly. 'In my zeal for my father's liberty, and my confidence in my own thews and sinews, I have not contemplated the possibility of death. My poor father! I am thy only son!--if I were to fall...' As the thought crossed him, the gladiator strode on with a more rapid and restless pace, when suddenly, in an opposite street, he beheld the very object of his thoughts. Leaning on his stick, his form bent by care and age, his eyes downcast, and his steps trembling, the grey-haired Medon slowly approached towards the gladiator. Lydon paused a moment: he divined at once the cause that brought forth the old man at that late hour. 'Be sure, it is I whom he seeks,' thought he; 'he is horror struck at the condemnation of Olinthus--he more than ever esteems the arena criminal and hateful--he comes again to dissuade me from the contest. I must shun him--I cannot brook his prayers--his tears.'
