The south gate spanned S. Aldate’s, close to the south-west corner of Christ Church; Little Gate was at the end of Brewer Street, and the west gate was in Castle Street, beyond the old Church of S. Peter-le-Bailly. From the south gate faint traces in “The Friars” indicate its course, and the indications are clear enough by New Inn Hall Street, Ship Inn Yard and Bullock’s Alley. Cornmarket Street was crossed by S. Michael’s Church, where stood the north gate. The gate house of the north gate was used as the town prison. It rejoiced in the name of Bocardo, jestingly so called from a figure in logic; for a man once committed to that form of syllogism could not expect to extricate himself save by special processes.
Old bastions and the line of the ditch are found behind the houses opposite Balliol College. The site of Balliol College was then an open space, and Broad Street was Canditch. This name was derived by Wood from Candida Fossa, a ditch with a clear stream running along it. Wood’s etymology is not convincing. Mr Hurst has suggested a more likely derivation in Camp Ditch. As a street name it reached from the angle of Balliol to Smith Gate. An indication of the old fosse, filled up, is to be found in the broad gravel walk north of the wall near New College.
From Bocardo the wall ran towards the Sheldonian Theatre. The outer line of the passage between Exeter Chapel and the house to the north of it was the line of the south face of the old city wall. A bastion was laid bare in 1852 in the north quad of Exeter. The wall passed in a diagonal line across the quadrangle south of the Clarendon Building, turned northwards in Cat’s Street, and ran up to the octagonal Chapel of Our Lady by Smith Gate. The remains of this little chapel, with a beautiful little “Annunciation” in a panel over the south entrance, have recently been revealed to the passer-by by the new buildings of Hertford College, between which and the feeble mass of the Indian Institute it seems strangely out of place.
From Smith Gate the wall returned to New College, and so completed the circuit of the town. A reference to the map will elucidate this bare narration of mine.
But to return to Robert D’Oigli, the Conqueror’s Castellan. From what little we know of him, he would appear to have been a typical Norman baron, ruthless, yet superstitious, strong to conquer and strong to hold. Very much the rough, marauding soldier, but gifted with an instinct for government and order, he came over to the conquest of England in the train of William the Bastard and in the company of Roger D’Ivry, his sworn brother, to whom, as the chronicler tells us, he was “iconfederyd and ibownde by faith and sacrament.” Oxfordshire was committed to his charge by the Conqueror, to reduce to final subjection and order. He seems to have ruled it in rude soldierly fashion, enforcing order, tripling the taxation of the town and pillaging without scruple the religious houses of the neighbourhood. For it was only by such ruthless exaction that the work which William had
