This famous courtezan, whose beauty was justly celebrated, feeling herself eaten away by an internal disease, promised to give a hundred louis to a doctor named Lucchesi, who by dint of mercury undertook to cure her, but Ancilla specified on the agreement that she was not to pay the aforesaid sum till Lucchesi had offered with her an amorous sacrifice. The doctor having done his business as well as he could wished to be paid without submitting to the conditions of the treaty, but Ancilla held her ground, and the matter was brought before a magistrate. In England, where all agreements are binding, Ancilla would have won her case, but at Venice she lost it. The judge, in giving sentence, said a condition, criminal per se, not fulfilled, did not invalidate an agreement--a sentence abounding in wisdom, especially in this instance. Two months before this woman had become disgusting, my friend M. Memmo, afterwards procurator, asked me to take him to her house. In the height of the conversation, what should come but a gondola, and we saw Count Rosemberg, the ambassador from Vienna, getting out of it. M. Memmo was thunderstruck (for a Venetian noble conversing with a foreign ambassador becomes guilty of treason to the state), and ran in hot haste from Ancilla's room, I after him, but on the stair he met the ambassador, who, seeing his distress, burst into a laugh, and passed on. I got directly into M. Memmo's gondola, and we went forthwith to M. Cavalli, secretary to the State Inquisitors. M. Memmo could have taken no better course to avoid the troublesome consequences which this fatal meeting might have had, and he was very glad that I was with him to testify to his innocence and to the harmlessness of the occurrence. M. Cavalli received M. Memmo with a smile, and told him he did well to come to confession without wasting any time. M. Memmo, much astonished at this reception, told him the brief history of the meeting, and the secretary replied with a grave air that he had no doubt as to the truth of his story, as the circumstances were in perfect correspondence with what he knew of the matter. We came away extremely puzzled at the secretary's reply, and discussed the subject for some time, but then we came to the conclusion that M. Cavalli could have had no positive knowledge of the matter before we came, and that he only spoke as he did from the instinct of an Inquisitor, who likes it to be understood that nothing is hid from him for a moment.
