Chapter IV

.); but that he built himself a personal castle is unlikely.[195]

It is the more unlikely, because the Danes in Normandy do not appear to have built personal castles until the feudal system was introduced there by Richard Sans Peur. The settlement in Normandy was not on feudal lines. "Rollo divided out the lands among his powerful comrades, and there is scarcely any doubt that they received these lands as inheritable property, without any other pledge than to help Rollo in the defence of the country."[196] "The Norman constitution at Rollo's death can be described thus, that the duke ruled the country as an independent prince in relation to the Franks; but for its internal government he had a council at his side, whose individual members felt themselves almost as powerful as the duke himself."[197] Sir Francis Palgrave asserts that feudalism was introduced into Normandy by the Duke Richard Sans Peur, the grandson of Rollo, towards the middle of the 10th century. He "enforced a most extensive conversion of allodial lands into feudal tenure," and exacted from his baronage the same feudal submission which he himself had rendered to Hugh Capet.[198]

It is quite in accordance with this that in the narrative of Dudo, who is our only authority for the history of Normandy in the 10th century, there is no mention of a private castle anywhere. We are told that Rollo restored the walls and towers of the _cities_ of Normandy,[199] and it is clear from the context that the _castra_ of Rouen, Fécamp, and Evreux, which are mentioned, are fortified cities, not castles. Even the ducal residence at Rouen is spoken of as a _palatium_ or an _aula_, not as a castle; and it does not appear to have possessed a keep until (as we are told by a later writer) the same Duke Richard who introduced the feudal system into Normandy built one for his own residence.[200] It is possible that when the feudal oath was exacted from the more important barons, permission was given to them to build castles for themselves; thus we hear from Ordericus of the castle of Aquila, built in the days of Duke Richard; the castle of the lords of Grantmesnil at Norrei; the castle of Belesme; all of which appear to have been private castles.[201] But there seems to have been no general building of castles until the time of William the Conqueror's minority, when his rebellious subjects raised castles against him on all sides. "Plura per loca aggeres erexerunt, et tutissimas sibi munitiones construxerunt."[202] It is generally, and doubtless correctly, supposed that _aggeres_ in this passage means mottes, and taking this statement along with the great number of mottes which are still to be found in Normandy, it has been further assumed (and the present writer was disposed to share the idea) that this was the time of the first invention of mottes. But the facts which have been now adduced, tracing back the first known mottes to the time of Thibault-le-Tricheur, and the county of Blois, show that the Norman claim to the invention of this mode of fortification must be given up. If the Normans were late in adopting feudalism, they were probably equally late in adopting private castles, and the fortifications of William I.'s time were most likely copied from castles outside the Norman frontier.[203]

It might be thought that the general expectation of the end of the world in the year 1000, which prevailed towards the end of the 10th century, had something to do with the spread of these wooden castles, as it might have seemed scarcely worth while to build costly structures of stone. But it is not necessary to resort to this hypothesis, because there is quite sufficient evidence to show that long before this forecast of doom was accepted, wood was a very common, if not the commonest, material used in fortification. The reader has only to open his Cæsar to see how familiar wooden towers and wooden palisades were to the Romans; and he has only to study carefully the chronicles of the 9th, 10th, 11th, and 12th centuries to see how all-prevalent this mode of fortification continued to be. The general adoption of the feudal system must have brought about a demand for cheap castles, which was excellently met by the motte with its wooden keep and its stockaded bailey. M. Enlart has pointed out that wooden defences have one important advantage over stone ones, their greater cohesion, which enabled them to resist the blows of the battering-ram better than rubble masonry.[204] Their great disadvantage was their liability to fire; but this was obviated, as in the time of the Romans, by spreading wet hides over the outsides. Stone castles were still built, where money and means were available, as we see from Fulk Nerra's keep at Langeais; but the devastations of the Northmen had decimated the population of Gaul; labour must have been dear, and skilled masons hard to find. In these social and economic reasons we have sufficient cause for the rapid spread of wooden castles in France.

The sum of the evidence which we have been reviewing is this: the earliest mottes which we know of were _probably_ built by Thibault-le-Tricheur about the middle of the 10th century. But in the present state of our knowledge we must leave the question of the time and place of their first origin open. The only thing about which we can be certain is that they were the product of feudalism, and cannot have arisen till it had taken root; that is to say, not earlier than the 10th century.
