Suffice it, however, to say, in a few words, that this adherence to his word, once pledged, was the only virtue he had retained through life. A stubborn adhesion to his resolutions of any kind had characterized him even as a boy, and it had become a matter of pride with him to abide by what he had said. The difficulty with him now was that Ramiro d'Orco would indubitably require assistance from his own hand in taking vengeance upon Lorenzo Visconti, if some means could not be found to betray the young nobleman into some dangerous act which would fall back upon his own head. This scheme had flashed suddenly through his mind while conversing with Ramiro; and he saw in it the only means of escaping from the breach of his word, or the acknowledgment of scruples which he knew would be treated with contempt. The plan when he first suggested it, was without form or feature; but now his busy and crafty brain eagerly pursued the train, and a thousand schemes suggested themselves, some of which were feasible, some wild and hopeless. During all this time, however, he forgot not his immediate errand. He watched everything passing in the street around him, and looked in at the two small taverns in the street of the citadel. There was a better inn, however, on the small square by the bishop's palace, where were also most of the best houses of the city, and thither Mardocchi bent his way. On reaching it, he entered the great court-yard, and inquired if any strangers had arrived that day. "Yes, father," replied the ostler to whom he spoke, "some seven or eight; one gentleman, with four or five servants and three sumpter mules, and two or three other persons." "I will go into the stable and see the horses, my son," said Mardocchi. "You know I am fond of a fine beast, and my own mule has not its match in Imola." The two strolled onward to the stable door, conversing familiarly, as was the custom with friar and citizen in those days; and Mardocchi passed down the line of stalls, discussing the merits of the horses, till at length he laid his hand upon the haunch of a fine grey barb, saying, "I want to see the man who rode this horse." "He is within, at dinner in the hall," answered the ostler. "He came himself to see his horse fed while they got ready for him. He is a careful signor, and marks everything he sees. He told me in a minute that those other horses belong to the great maestro Leonardo da Vinci though he did not know him, for they passed each other close without speaking." "I will go in and see him," said the friar; and entering the inn by the back way, he strolled into the dining-hall with an indifferent and purposeless look, as if there was no object in his coming. Antonio was sitting alone at a table, with his back towards the door by which Mardocchi entered; but the tread of the latter upon the rushes which strewed the floor made the other turn sharply round as he came near.
