The Icening-street runs between this hill and the Bourn river, coming from Newberry, as I suppose, through Chute forest, where vulgarly called Chute causeway: at Lurgishal it makes a fine terrace-walk in the garden of Sir Philip Medows; then passes the Bourn river about Tudworth, and so by this place to the eastern gate of Old Sarum, the Roman _Sorbiodunum_, where it runs most precisely north-east and south-west, as we said before. This city is perfectly round, and formed upon one of the most elegant designs one can imagine: probably a fortress of the old Britons, and I fancy somewhat like the famous Alesia in Gaul, memorable for the ancient Hercules, its founder, and for the siege of the great Cæsar; which only his genius could have taken in his circumstances. The prospect of this place is at present very august, and would have afforded us a most noble sight when in perfection: such a one will not be difficult to conceive when we have described it. It fills up the summit of a high and steep hill, which originally rose equally on all sides to an _apex_: the whole work is 1600 foot diameter, included in a ditch of a prodigious depth: it is so contrived that in effect it has two ramparts, the inner and outer, the ditch between: upon the inner, which is much the higher, stood a strong wall of twelve foot thick, their usual standard, which afforded a parapet at top for the defendants, with battlements quite round: upon still higher ground is another deep circular ditch, of 500 foot diameter; this is the castle or citadel. Upon the inner rampire of this was likewise another wall, I suppose of like thickness: so that between the inner ditch and the outer wall, all around, was the city. This is divided into equal parts by a meridian line: both the banks are still left; one to the south, the other to the north; and these had walls upon them too: the traces of all the walls are still manifest, and some parts of them left; but we may say with the poet of the whole, ————_lapsis ingentia muris Saxa jacent, nulloque domus custode tenetur._ +Lucan.
