His successor, #William de Turbe# (1146-1174), was elected to the see, and in the year 1146 was consecrated at Canterbury by Archbishop Theobald. In 1168, Becket had written to De Turbe from Vezelay, a town on the borders of Burgundy and Nivernois, and ordered him, by the Pope's authority, to publicly excommunicate Hugh Bigot, Earl of Norfolk. He had robbed the Priory of Pentnay, in Norfolk, of some of its possessions. De Turbe obeyed, notwithstanding the fact that the king had sent officers to prohibit him from so doing. An absolution was obtained from the Pope, but the king was so far incensed that De Turbe considered it advisable to rest in sanctuary at Norwich until the following year, 1169, when he received the royal pardon. [Illustration: Norwich Castle.] Bishop William de Turbe died 17th January 1174, and was buried in the cathedral choir, on the left side of the founder. #John of Oxford# (1175-1200) was consecrated at Lambeth by Richard, Archbishop of Canterbury, December 14, 1175; he was clerk or royal chaplain to the king. He had presided over the council of Clarendon, the constitutions of which defined the king's prerogatives in regard to the Church, and chiefly with regard to the question of trying clerks charged with crimes in the civil courts. He was despatched to Rome on an embassy to the Pope, Alexander III., and on its failure was sent by Henry to the Diet at Wurzburg; the king, not having been supported by Alexander, determined to uphold his opponent, and as well he, in direct opposition to the Pope, made John of Oxford Dean of Salisbury, with the result that the future Bishop of Norwich incurred the penalty of excommunication by Becket from Vezelay, "for having fallen into a damnable heresy in taking a sacrilegious oath to the emperor, for having communicated with the schismatic of Cologne, and for having usurped to himself the deanery of the church of Salisbury." The dispute was referred to the Pope at Sens, where John of Oxford, with his fellow-ambassador, Gilbert Foliot, Bishop of London, repaired; John of Oxford was rebuked by the Pontiff for his misconduct, but diplomatically managed to effect his end and retain his deanery. Henry had met Becket at Chaumont, through the mediation of the Archbishop of Sens, and, the quarrel being patched up, John of Oxford was sent to escort him to England. He landed, December 1, at Sandwich, in the year 1170, and within the month was murdered at Canterbury.
