But Fortune, noting with envious eye a happiness of such degree and duration, gave to events a dolorous turn, whereby the joy of the two lovers was converted into bitter lamentation. 'Twas Tancred's custom to come from time to time quite alone to his daughter's room, and tarry talking with her a while. Whereby it so befell that he came down there one day after breakfast, while Ghismonda--such was the lady's name--was in her garden with her damsels; so that none saw or heard him enter; nor would he call his daughter, for he was minded that she should not forgo her pleasure. But, finding the windows closed and the bed-curtains drawn down, he seated himself on a divan that stood at one of the corners of the bed, rested his head on the bed, drew the curtain over him, and thus, hidden as if of set purpose, fell asleep. As he slept Ghismonda, who, as it happened, had caused Guiscardo to come that day, left her damsels in the garden, softly entered the room, and having locked herself in, unwitting that there was another in the room, opened the door to Guiscardo, who was in waiting. Straightway they got them to bed, as was their wont; and, while they there solaced and disported them together, it so befell that Tancred awoke, and heard and saw what they did: whereat he was troubled beyond measure, and at first was minded to upbraid them; but on second thoughts he deemed it best to hold his peace, and avoid discovery, if so he might with greater stealth and less dishonour carry out the design which was already in his mind. The two lovers continued long together, as they were wont, all unwitting of Tancred; but at length they saw fit to get out of bed, when Guiscardo went back to the grotto, and the lady hied her forth of the room. Whereupon Tancred, old though he was, got out at one of the windows, clambered down into the garden, and, seen by none, returned sorely troubled to his room. By his command two men took Guiscardo early that same night, as he issued forth of the orifice accoutred in his suit of leather, and brought him privily to Tancred; who, as he saw him, all but wept, and said:--"Guiscardo, my kindness to thee is ill requited by the outrage and dishonour which thou hast done me in the person of my daughter, as to-day I have seen with my own eyes." To whom Guiscardo could answer nought but:--"Love is more potent than either, you or I." Tancred then gave order to keep him privily under watch and ward in a room within the palace; and so 'twas done. Next day, while Ghismonda wotted nought of these matters, Tancred, after pondering divers novel expedients, hied him after breakfast, according to his wont, to his daughter's room, where, having called her to him and locked himself in with her, he began, not without tears, to speak on this wise:--"Ghismonda, conceiving that I knew thy virtue and honour, never, though it had been reported to me, would I have credited, had I not seen with my own eyes, that
