OLD SARUM, Wilts (Fig. 30).--Sir Richard Colt Hoare printed in his _Ancient Wiltshire_ a document purporting to be an order from Alfred, "King of the English," to Leofric, "Earl of Wiltunshire," to maintain the castle of Sarum, and add another ditch to it.[635] The phraseology of the document suggests some doubts of its genuineness, and though there would be nothing improbable in the theory that Alfred reared the outer bank of the fortress, recent excavations have shown that the place was occupied by the Romans, and therefore make it certain that its origin was very much earlier than Alfred's time. Moreover, the convergence of several Roman roads at this spot suggests the probability of a Roman station,[636] while the form of the enclosure renders an earlier origin likely. Domesday Book does not speak of Salisbury as a _burgus_, and when the _burgus_ of Old Sarum is mentioned in later documents it appears to refer to a district lying at the foot of the Castle Hill, and formerly enclosed with a wall.[637] Nor is it one of the boroughs of the _Burghal Hidage_. But that Sarum was an important place in Saxon times is clear from the fact that there was a mint there; and there is evidence of the existence of at least four Saxon churches, as well as a hospital for lepers.[638] For more exact knowledge as to the history of this ancient fortress we must wait till the excavations now going on are finished, but in the meanwhile it seems probable that the theory adopted by General Pitt-Rivers is correct. He regarded Old Sarum as a British earthwork, with an inner castle and outer barbicans added by the Normans. After building this castle in the midst of it the Normans appear to have considered the outer and larger fortification too valuable to be given up to the public, but retained it under the government of the castellan, and treated it as part of the castle. There is no mention of the castle of Salisbury in Domesday Book, but the bishop is named as the owner of the manor.[639] The episcopal see of Sherborne was transferred to Sarum in 1076 by Bishop Hermann, in accordance with the policy adopted by William I. that episcopal sees should be removed from villages to towns:[640] a measure which in itself is a testimony to the importance of Salisbury at that time. The first mention of the castle is in the charter of Bishop Osmund, 1091.[641] The bishop was allowed to lay the foundations of his new cathedral within the ancient fortress. As might be expected, friction soon arose between the castellans and the ecclesiastics; the castellans claimed the custody of the gates, and sometimes barred the canons, whose houses seem to have been outside the fortress, from access to the church. These quarrels were ended eventually by the removal of the cathedral to the new town of Salisbury at the foot of the hill. [Illustration: FIG. 30. Old Sarum, Wilts.]
