Now it happed that the Emperor Constantine did do slay all the Christian men over all where he could find them, and for this cause St. Silvester fled out of the town with his clerks, and hid him in a mountain.  And for the cruelty of Constantine God sent him such a sickness that he became lazar and measel, and by the counsel of his physicians he got three thousand young children for to have cut their throats, for to have their blood in a bath all hot, and thereby he might be healed of his measelry.  And when he should ascend into his chariot for to go to the place where he should be bathed, the mothers of the children came crying and braying for sorrow of their children, and when he understood that they were mothers of the children, he had great pity on them and said to his knights and them that were about him:  The dignity of the empire of Rome is brought forth of the fountain of pity, the which hath stablished by decree that who that slayeth a child in battle shall have his head smitten off, then should it be great cruelty to us for to do to ours such thing as we defend to strange nations, for so should cruelty surmount us.  It is better that we leave cruelty and that pity surmount us, and therefore me seemeth better to save the lives of these innocents, than by their death I should have again my health, of the which we be not yet certain.  Ne we may recover nothing for to slay them, for if so were that I should thereby have health, that should be a cruel health that should be bought with the death of so many innocents.  Then he commanded to render and deliver again to the mothers their children, and gave to every each of them a good gift, and thus made them return to their houses with great joy, from whence they departed with great sorrow, and he himself returned again in his chariot unto his palace.  Now it happed that the night after St. Peter and St. Paul appeared to this Emperor Constantine, saying to him:  Because thou hast had horror to shed and spill the blood of innocents, our Lord Jesu Christ hath had pity on thee, and commandeth thee to send unto such a mountain where Silvester is hid with his clerks, and say to him that thou comest for to be baptized of him and thou shalt be healed of thy malady.  And when he was awaked he did do call his knights and commanded them to go to that mountain and bring the Pope Silvester to him courteously and fair, for to speak with him.  When St. Silvester saw from far the knights come to him, he supposed they sought him for to be martyred, and began to say to his clerks that they should be firm and stable in the faith for to suffer martyrdom.  When the knights came to him they said to him much courteously that Constantine sent for him, and prayed him that he would come and speak with him.  And forthwith he came, and when they had intersaluted each other, Constantine told to him his vision.  And when Silvester demanded of him what men they were that so appeared to him, the emperor wist not ne could not name them.  St.
