586 hiding-place on Mount Soracte, disclosed the identity of the gods seen in his dream, and not only cured but converted and baptised him. Thereupon the grateful monarch, proclaiming throughout the Empire his new faith, provided by edict for its safety and support, made all bishops subject to the Pope, even as are all magistrates to the Emperor, and, setting forth to found elsewhere a capital, first laid with his own hands the foundations of St Peter's and the Lateran.

It was doubtless faith in this wild tale which led the rueful Carloman, fain to atone for his own deeds of violence, to choose Sylvester's cave for his retreat and dedicate his convent to that saint. The legend must thereby have gained a wider currency among the Franks; and none could know this better than the papal court. Was it for use with them, and was it now, that there came into existence a document which made the myth a cornerstone of papal power — the so-called Donation of Constantine?

No extant manuscript of that famous forgery is older than the early ninth century, and what most scholars have believed a quotation from it by Pope Hadrian in 778 can possibly be otherwise explained; but minute study of the strange charter's diction seems now to have made sure its origin in the papal chancellery during the third quarter of the eighth century, and startling coincidences of phrase connect it in particular with the documents of Stephen II and of Paul, while to an ever-growing proportion of the students of this period the historical setting in which alone it can be made to fit is that of Stephen's visit to the Franks or of the years which closely follow it.
