'Mocks us! Well, I will show him how to mock at me! I will complain to the Duke! I will give that scurvy piece, Ambrogio, a lesson he shall not forget! the Lord send him an evil Easter!'

Marco made a vague gesture, as if to say it was not Leonardo who would teach lessons to the Duke's treasurer. Then an expression of kindness and love came over his hard features, and he added soothingly:—

'No, no, Master, let it be! God is merciful, and we shall get along in some fashion. If you really take it to heart, I will find the money even for your oats.'

And Marco reflected that he could use some of his own money, a little hoard he had been making for his mother.

'The oats are not the major question,' said Leonardo, sinking wearily on a chair, and defending his eyes as if from a cruel wind. 'Hearken, friend, there is a thing I have not yet told you; next month I shall absolutely require eighty ducats, which I have had on loan. There is no need to stare at me with those eyes, Marco.'

'Of whom had you the loan?'

'Of the money-changer, Arnoldo—'

'Of Arnoldo! Oh, Master! what have you done? Don't you know he is worse than any infidel or any Jew? Why did you not tell me at once?'

Leonardo hung his head.

'I wanted the money—be not so wroth, Marco!' he said; and added piteously, 'Bring the reckonings, perhaps we shall be able to devise something.'
