"Yea," I answered "that of God, and there is also my power with which it seems you have forgotten to reckon."

He looked at me and laughed. "That for your power," he scoffed, snapping his fingers.

We had planned to ride to Nemi to find Napoleone Orsini but at Frascati we were met by a messenger who gave Ippolito a letter. On reading it he told me excitedly that Pompeo Colonna was besieged in his monastery of Subiaco by a rabble of the Orsini.

"Go, and hold them in play," he commanded, "and I will hasten on to Nemi and fetch Napoleone with me, to command his clansmen to raise the siege."

The plan commended itself to my reason and, suspecting no treachery, I galloped off with my troop for the relief of Pompeo. Ippolito shouted to me to await his coming at Subiaco, and I might have remained there until this day had I obeyed him. But at the monastery to my surprise I found all quiet nor had there been any fighting since the previous year, when the papal troops had been beaten by the monks and left their banner behind them. Both Cardinal Pompeo and I were puzzled by the false news which had brought me in such haste, but, being where we were, we accepted the hospitality of the monastery and rested and refreshed ourselves for three hours and no more. For, at the expiration of that time, came an aged man clad in Oriental garments, who had escaped from Palliano that morning while Napoleone Orsini was sacking the town. The castle on the summit of the cliff was unstormed when he left, but its fall was inevitable unless help should speedily arrive. Then I knew how Ippolito de' Medici had tricked me, for he desired not my company at Palliano, where he wished to pose as the sole rescuer of its ladies.

The messenger whom my sister had sent to Subiaco was the Moorish alchemist who had taught Fenice to make the fire balloons, and I was at first encouraged by his assurance that the fortress was well munitioned, and that he had manufactured great quantities of gunpowder which was stored in its donjon. But I reflected that this circumstance was but an added danger as the assailants were endeavouring to fire the castle.

With this news the Cardinal ordered his bravi to horse, and the monks girded up their gowns for the march. As fighting men the latter suffered no disparagement when matched with my soldiery save in their weapons, for, as their vows forbade them to take the sword, they were forced to content themselves with battle-axes.

Wearied as were our horses my troop took the lead, and all night by toilsome ways over the mountains we rode toward Palliano, in the vain hope of arriving there before Ippolito in spite of the long detour which he had foisted upon us; and I felt no fatigue, for I rode for my sister's honour and the life of her I loved.

But, in the grey dawn, at the little town of Genazzano, some six miles from the Colonna stronghold, I met Ippolito and his escort returning from Palliano, for he, too, had ridden hard. His face was drawn and white, but he faced me unflinchingly.

"You need not have come," he said, "for I have given Napoleone Orsini the mandate of his Holiness. He will draw off his men. They will leave the castle of Palliano unattacked. I was too late to save the town."
