Dear reader, a picture must have shades, and there is nothing, no matter how beautiful in one point of view, that does not require to be sometimes veiled if you look at it from a different one. In order to paint the diversified scene which took place between me and my lovely mistress until the dawn of day, I should have to use all the colours of Aretino's palette. I was ardent and full of vigour, but I had to deal with a strong partner, and in the morning, after the last exploit, we were positively worn out; so much so that my charming nun felt some anxiety on my account. It is true that she had seen my blood spurt out and cover her bosom during my last offering; and as she did not suspect the true cause of that phenomenon, she turned pale with fright. I allayed her anxiety by a thousand follies which made her laugh heartily. I washed her splendid bosom with rosewater, so as to purify it from the blood by which it had been dyed for the first time. She expressed a fear that she had swallowed a few drops, but I told her that it was of no consequence, even if were the case. She resumed the costume of a nun, and entreating me to lie down and to write to her before returning to Venice, so as to let her know how I was, she left the casino. I had no difficulty in obeying her, for I was truly in great need of rest. I slept until evening. As soon as I awoke, I wrote to her that my health was excellent, and that I felt quite inclined to begin our delightful contest all over again. I asked her to let me know how she was herself, and after I had dispatched my letter I returned to Venice. CHAPTER XIX I Give My Portrait to M.
