They called her that season the Firefly, and many misinterpreted her illy suppressed excitement and the scrutiny of those lambent eyes sending out their flame signals in search of answering lights. Even her secretary did not know that the dark shadows which ringed them were not due to the balls and other frivolities in which she was so conspicuous; but to complicated and dangerous schemes which robbed her of sleep at night, and were never forgotten as she danced and chatted and coquetted while the most astute diplomats laid their hearts and their secrets at her feet. She received strange visitors too at the magnificent Villa Borghese, just outside the Porta del Popolo, wild-eyed agitators and suspects who had never before been permitted to enter those aristocratic gates. The first had come disguised in a marble-cutter's blouse as an assistant of Canova; but he had dropped a word which the noble model understood, and the fire signals had flashed between them. After the sculptor had left the casino his assistant tarried, and Celio, dismissed by his mistress but lingering at the threshold, heard fragments of the man's talk: "Liberty, united Italy, and death to the Austrians." Later, when he attempted to warn the Princess that if the man were not a maniac he was more dangerous, she asked him bluntly if her husband had constituted him her dragon, and thereafter in half contemptuous banter she gave him the nickname of "Mondragone." It was the name also of another villa belonging to the Borghese, the most sightly of all the boldly seated summer resorts of the nobility at beautiful Frascati. Not one of these commands a view comparable to the one from its terrace of the Pope's Chimneys, so named from the strange monumental constructions which are so conspicuous that, with a glass, they are plainly visible from Rome. So when the Princess announced, "I love Mondragone," her secretary did not flatter himself that the equivocal utterance bore any reference to himself. Had he also had the wit to perceive that if she indeed cared for the villa or for any other object at this time, it was only for some service which it might render her brother, his duties as dragon would have occasioned him far less of mental anguish. Celio was writing one day in a room adjoining the apartment which Canova had used as his studio in the casino of Villa Borghese, when he was startled by a heavy step in the room which he had supposed unoccupied. Throwing aside the portiere he instantly recognised from report the imposing figure which confronted him. On a lesser man so gorgeous a costume as the one which now dazzled the astonished eyes of the secretary would have suggested the mountebank; but there was something regal as well as Oriental in Joachim Murat's appearance, and the barbarous colour extravagances of his dress became him like those of a sultan.
