’Hush! Why should we fear rain and thunder? God put His bow in the sky. Jacopo, it is a sweet and fearful thing to be chosen minister of one of His purifications—Noah, and Lot, and now thy prince.’ ’Purification?’ said the executioner: ’by what?’ ’By love, thou fool!’ whispered Galeazzo, half ecstatic, half furious, with a nervous glance about him. ’There were the purifications by water one, one by fire, and a third by blood, to the last of which His servants yet testify in the spirit of their Redeemer. Blood, Jacopo, thou little monster—blood flowing, streams of it, the visible token of the sacrifice. That was our task till yesterday. Now in the end comes Love, and calleth for a cleansed and fruitful soil. Let us hasten with the last tares—to cut them down, and let their blood consummate the fertilising. Quick: we have no time to lose.’ He flung himself from the statue, and tiptoed, in a sort of gloating rapture, to the door. ’Show me this tare, I say.’ He went down the tower a few paces, with assured steps, then, bethinking himself, beckoned the other to lead. The flight conducted them to a private postern, well secured and guarded inside and out. As they issued from this, the howl of blown rain met and staggered them. Looking up at the blackened sky from the depths of that well of masonry, it seemed to crack and split in a rush of fusing stars. The mad soul of the tyrant leapt to speed the chase. He was one with this mighty demonstration—as like a chosen instrument of the divine retribution. His brain danced and flickered with exquisite visions of power. He was an angel, a destroying angel, commissioned to purge the world of lies. ’Bring me to this monk!’ he screamed through the thunder.
