"Such was the honorable office intrusted to me," was the reply. "When messengers from Villiers of Isle-Adam arrived in Florence, beseeching succor against this invasion, which has, alas! proved too successful, I panted for occupation to distract my mind from ever pondering on the heavy misfortunes which had overtaken me." "Misfortunes!" exclaimed Ibrahim. "Yes--misfortunes of such a nature that the mere thought of them is madness!" cried Francisco, in an excited tone. "First, a beauteous and amiable girl--one who, though of humble origin, was endowed with virtues and qualifications that might have fitted her to adorn a palace, and whom I fondly, devotedly loved--was-snatched from me. She disappeared I know not how! All trace of her was suddenly lost, as if the earth had swallowed her up and closed over her again! This blow was in itself terrible. But it came not alone. A few days elapsed, and my sister--my dearly beloved sister--also disappeared, and in the same mysterious manner. Not a trace of her remained--and what makes this second affliction the more crushing--the more overwhelming, is that she is deaf and dumb! Oh! Heaven grant me the power to resist, to bear up against these crowning miseries! Vain were all my inquiries--useless was all the search I instituted to discover whither had gone the being whom I would have made my wife, and the sister who was ever so devoted to me! At length, driven to desperation, when weeks had passed and they returned not--goaded on to madness by bitter, bitter memories--I resolved to devote myself to the service of the cross. With my gold I raised and equipped a gallant band; and a favoring breeze wafted us from Leghorn to this island. The grand master received me with open arms; and, forming an estimation of my capacities far above my deserts, placed me in command of all the Italian auxiliaries. You know the rest; I fought with all my energy, and your sultan was within the grasp of death, when you rushed forward and saved him. The result is that I am your prisoner." "So young--and yet so early acquainted with such deep affliction!" exclaimed Ibrahim. "But can you form no idea, Christian, of the cause of that double disappearance? Had your sister no attendants who could throw the least light upon the subject?" he asked, with the hope of eliciting some tidings relative to his own sister, the beauteous Flora. "I dare not reflect thereon!" cried Francisco, the tears starting into his eyes. "For, alas! Florence has long been infested by a desperate band of lawless wretches--and my God! I apprehend the worst--the very worst." Thus speaking, he rose and paced the spacious tent with agitated steps; for this conversation had awakened in his mind all the bitter thoughts and dreadful alarms which he had essayed to subdue amidst the excitement and peril of war. A slave now entered to inform Ibrahim that the sultan commanded his immediate presence in the imperial pavilion.
