“Listen, Caterina, and try and comprehend me better than I know how to express myself. Do you give your whole attention?”

“Yes,” said the other with an effort.

“You alone know how we have loved each other here. After God, the Madonna Addolorata, and my father, I have loved you, Caterina. You have saved my life, I can never forget it. But for you, I should have gone to burn in hell, where suicides must eternally suffer. I thank you, dear heart. You believe in my gratitude?”

“Yes,” said Caterina, opening wide her eyes the better to understand her.

“Now we who so love each other must part. You go to the left, I to the right. You are to be married. I know not what will happen to me. Shall we meet again? I know not. Shall we again come together in the future? Who knows? Do you know?”

“No,” replied Caterina, starting.

“Well, then, I propose to you to conquer time and space, men and circumstances, should they stand in the way of our affection. From afar, howsoever we may be separated, let us love each other as we do to-day, as we did yesterday. Do you promise?”

“I promise.”

“The Madonna hears us, Caterina. Do you promise with a vow, with an oath?”

“With a vow, with an oath,” repeated Caterina, monotonously, like an echo.
