Calmly the stars looked down upon him from the azure vault of heaven.
And like a spider in his web, Johannes Crescentius sat in Castel San Angelo.
CHAPTER VIII
THE GOTHIC TOWER
eep quiet reigned in the city, when a man, enveloped in a mantle, whose dimly shadowed form was outlined against the massive, gray walls of Constantine's Basilica glided slowly and cautiously from among the blocks of stone scattered round its foundations and advanced to the fountain which then formed the centre of the square, where the Obelisk now stands. There he stopped and, concealed by the obscurity of the night and the deeper shadows of the monument, glanced furtively about, as if to be sure that he was unobserved. Then drawing his sword, he struck three times upon the pavement, producing at each stroke light sparks from its point. This signal, for such it was, was forthwith answered. From the remote depths of the ruins the cry of the screech-owl was thrice in succession repeated, and, guided by the ringing sound, a second figure emerged from the weeds, which were in some places the height of a man. Obeying the signal of the first comer, the second, who was likewise enveloped in a mantle, silently joined him and together they proceeded half-way down the Borgo Vecchio, then turned to the right and entered a street, at the remote extremity of which there was a figure of the Madonna with its lamp.
Onward they walked with rapid steps, traversed the Borgo Santo Spirito and followed the street Della Lingara to where it opens upon the church Regina Coeli. After having pursued their way for some time in silence they entered a narrow winding path, which conducted them through a deserted valley, the silence of which was only broken by the occasional hoot of an owl or the fitful flight of a bat. In the distance could be heard the splashing of water from the basin of a fountain, half obscured by vines and creepers, from which a thin, translucent stream was pouring and bubbling down the Pincian hillsides in the direction of Santa Trinita di Monte.
They lost themselves in a maze of narrow and little frequented lanes, until at last they found themselves before a gray, castellated building, half cloister, half fortress, rising out of the solitudes of the Flaminian way, before which they stopped. Over the massive door were painted several skeletons in the crude fashion of the time, standing upright with mitres, sceptres and crowns upon their heads, holding falling scrolls, with faded inscriptions in their bony grasp.
The one, who appeared to be the moving spirit of the two, knocked in a peculiar manner at the heavy oaken door. After a wait of some duration they heard the creaking of hinges. Slowly the door swung inward and closed immediately behind them. They entered a gloomy passage. A number of owls, roused by the dim light from the lantern of the warden, began to fly screeching about, flapping their wings against the walls and uttering strange cries. After ascending three flights of stairs, preceded by the warden, whose appearance was as little inviting as his abode, they paused before a chamber, the door of which their guide had pushed open, remaining himself on the threshold, while his two visitors entered.
"How is the girl?" questioned the foremost in a whisper, to which the warden made whispered reply.
