‘It was the belief that my labour, if successful, would prove a benefit to the world, that has upheld me under much disappointment and poverty.’

‘Very disinterested and laudable,’ said Afer, in a tone which brought a laugh to the lips of the Prefect.

‘You would seem to doubt my sincerity, noble sir,’ said the potter, bestowing a keen glance on the knight, and at the same time opening his wallet, ‘and without being selfish, I think that my long labour and sacrifices should meet with a just return, if the fruit of it prove of real service to others.’

‘Doubtless,’ quoth Afer.

‘Doubtless,’ murmured Caesar, and the knight became silent.

‘This is the specimen I have made to test my words,’ proceeded Masthlion, as he drew out a plain bowl of dull-coloured glass. He handed it to Zeno, who stood by, and the Greek took it to his master who briefly examined it. With a shrug of his shoulders it was handed back to the steward. A smile rested on the lips of the potter.

‘It is true that its appearance has nothing to commend it,’ said the latter, ‘but I will explain that, by saying, that it was made in haste during the past night, that I might hasten hither to-day. It is not the appearance of the glass I wish your highness to judge of—that can be made to suit every taste, with better appliances than my humble workshop possesses. The same principle which constructs this poor bowl can be [pg 316]applied to produce such costly and priceless articles as those I see there,’—he pointed to some magnificent vases on the table. ‘It is the nature of the material which forms my secret. You know of what worth those vases would be if flung on the floor; they would be shivered to a million atoms. Will Caesar bid the strongest slave take this poor bowl of mine and dash it on the floor with all his might, that he may see the result?’

Tiberius turned his head slightly toward his gigantic Nubian servant who stood behind him. The black went round and took the cup from Zeno. Raising it to the full height of his arm, he dashed it down on the marble floor with terrific force. The derisive smile on his thick lips changed to complete surprise, for, instead of the expected crash was a dull thud. He stooped quickly and lifted on high the bowl with one side completely flattened in.

Exclamations and murmurs of wonder arose, and the bowl was given over once more to the inspection of Caesar, from whom it was passed to the others.

‘Good,’ said Tiberius. ‘What next?’
