Phoebicius waved his hand with a negative movement, implying that he knew better, and said, "I will show you what your nice night-bird left in my nest. It may be that you can tell me to whom it belongs." Just as he hastily stepped across the court-yard to his own dwelling Paulus entered by the now open gate; he greeted the senator and his family, and offered Petrus the key of the church. The sun meanwhile had risen, and the Alexandrian blushed to show himself in Dame Dorothea's presence in his short and ragged under-garment, which was quite inefficient to cover the still athletic mould of his limbs. Petrus had heard nothing but good of Paulus, and yet he measured him now with no friendly eye, for all that wore the aspect of extravagance repelled his temperate and methodical nature. Paulus was made conscious of what was passing in the senator's mind when, without vouchsafing a single word, he took the key from his hand. It was not a matter of indifference to him, that this man should think ill of him, and he said, with some embarrassment: "We do not usually go among people without a sheepskin, but I have lost mine." Hardly had he uttered the words, when Phoebicius came back with Hermas' sheepskin in his hand, and cried out to Petrus: "This I found on my return home, in our sleeping-room."

You have lived here longer than I; who can have made me a present of this skin, which still seems to be pretty new--horns and all." Petrus examined and felt the skin, "This is an anchorite's garment," he said; "the penitents on the mountain are all accustomed to wear such." "It is one of those rascals then that has found his way into my house!" exclaimed the centurion. "I bear Caesar's commission, and I am to exterminate ill vagabonds that trouble the dwellers in the oasis, or travellers in the desert. Thus run the orders which I brought with me from Rome. I will drive the low fellows together like deer for hunting, for they are all rogues and villains, and I shall know how to torture them until I find the right one." "The emperor will ill-requite you for that," replied Petrus. "They are pious Christians, and you know that Constantine himself--"
