The history of Mont St. Michel in Normandy is well authenticated, particularly during the period which is of importance to us. Mabillon, quoting from the chronicler who wrote before the middle of the tenth century, relates how Autbert, the Bishop of Avranches, had a vision, and after having been thrice admonished by St. Michael, proceeded to build on the summit of the Mount a church under the patronage of the Archangel. This was in 708, or possibly a few years earlier, if Pagius is right in fixing the dedication of the temple in 707.[92] Mabillon points out that this chronicler says nothing as yet of the miracles related by later writers, particularly of the famous hole in the Bishop's skull, which it was believed St. Michael had made when on exhorting him the third time to build his church, he gently touched him with his archangelic finger. In doing this the finger went through the skull, and left a hole. The perforated skull did not interfere with the Bishop's health, and it was shown after his death as a valuable relic. The new church was dedicated by Autbert himself, and the day of the dedication (xvii. Kalend. Novemb.) was celebrated, not only in France, but also in England, as is shown by a decree of the Synod held at Oxford in 1222. The further history of the church and monastery of St. Michel may be read with all its minute details in Mabillon, or in the “Neustria Pia” (p. 371), or in the “Gallia Christiana” (vol. ix. p. [pg 329] 517 E, 870 A). What is of interest to us is that soon after the Conquest, when the ecclesiastical property of England had fallen into the hands of her Norman conquerors, Robert, Earl of Mortain and Cornwall, the half-brother of William the Conqueror, endowed the Norman with the Cornish Mount. A priory of Benedictine monks had existed on the Cornish Mount for some time, and had been richly endowed in 1044 by Edward the Confessor. Nay, if we may trust the charter of Edward the Confessor, it would seem that, even at that time, the Cornish Mount and its priory had been granted by him to the Norman Abbey, for the charter is witnessed by Norman bishops, and its original is preserved in the Abbey of Mont St. Michel. In that case William the Conqueror or his half-brother Robert would only have restored the Cornish priory to its rightful owners, the monks of Mont St. Michel, who had well deserved the gratitude of the Conqueror by supplying him after the Conquest with six ships and a number of monks, destined to assist in the restoration of ecclesiastical discipline in England. After that time the Cornish priory shared the fate of other so-called alien priories or cells. The prior was bound to visit in person or by proxy the mother-house every year, and to pay sixteen marks of silver as an acknowledgment of dependence. Whenever a war broke out between England and France, the foreign priories were seized, though some, and among them the priory of St. Michael's Mount obtained in time a distinct corporate character, and during the reigns of Henry IV. and Henry V. were exempted from seizure during war.

Under these circumstances we can well understand how in the minds of the monks, who spent their lives [pg 330] partly in the mother-house, partly in its dependencies, there was no very clear perception of any difference between the founders, benefactors, and patrons of these twin establishments. A monk brought up at Mont St. Michel would repeat as an old man the legends he had heard about St. Michel and Bishop Autbert, even though he was ending his days in the priory of the Cornish Mount. Relics and books would likewise travel from one place to the other, and a charter originally belonging to the one might afterwards form part of the archives of another house.

After these preliminary remarks, let us look again at the memoranda which William of Worcester made at St. Michael's Mount, and it will appear that what we anticipated has actually happened, and that a book originally belonging to Mont St. Michel in Normandy, and containing the early history of that monastery, was transferred (either in the original or in a copy) to Cornwall, and there used by William of Worcester in the belief that it contained the early history of the Cornish Mount and the Cornish priory.

The Memorandum of William of Worcester runs thus: “Apparicio Sancti Michaelis in monte Tumba, antea vocata le Hore-rok in the wodd; et fuerunt tam boscus quarn prata et terra arabilis inter dictum montem et insulas Syllye, et fuerunt 140 ecclesias parochiales inter istum montem et Sylly submersse.

“Prima apparicio Sancti Michaelis in monte Gorgon in regno Apuliae fuit anno Christi 391. Secunda apparicio fuit circa annum domini 710 in Tumba in Cornubia juxta mare.

“Tertia apparicio Romæ fuit; tempore Gregorii papæ legitur accidisse: nam tempore magnæ pestilenciæ, etc.

“Quarta apparicio fuit in ierarchiis nostrorum angelorum.

“Spacium loci mentis Sancti Michaelis est DUCENTORUM CUBITORUM UNDIQUE OCEANO CINCTUM, et religiosi monachi dicti loci. Abrincensis antistes Aubertus nomine, ut in honore Sancti Michaelis construeret ... predictus LOCUS OPACISSIMA PRIMO CLAUDEBATUR SYLVA, AB OCEANO MILIARIBUS DISTANS SEX, aptissimam prasbens latebram ferarum, in quo loco olim comperimus MONACHOS domino servientes.”

The text is somewhat corrupt and fragmentary, but may be translated as follows:—

“The apparition of St. Michael in the Mount Tumba, formerly called the Hore-rock in the wodd; and there were a forest and meadows and arable land between the said mount and the Syllye Isles, and there were 140 parochial churches swallowed by the sea between that mount and Sylly.
