CHAP. XXXIII. How Augustine repaired the church of our Saviour, and built the monastery of the blessed Peter the Apostle; and concerning Peter the first abbot of the same.

Augustine having had his episcopal see granted him in the royal city, as has been said, recovered therein, with the support of the king, a church, which he was informed had been built of old by the faithful among the Romans, and consecrated it in the name of the Holy Saviour, our Divine Lord Jesus Christ, and there established a residence for himself and all his successors.’ He also built a monastery not far from the city to the eastward, in which, by his advice, Ethelbert erected from the foundation the church of the blessed Apostles, Peter and Paul, and enriched it with divers gifts; wherein the bodies of the same Augustine, and of all the bishops of Canterbury, and of the kings of Kent, might be buried. Nevertheless, it was not Augustine himself who consecrated that church, but Laurentius, his successor.

The first abbot of that monastery was the priest Peter, who, being sent on a mission into Gaul, was drowned in a bay of the sea, which is called Amfleat, and committed to a humble tomb by the inhabitants of the place; but since it was the will of Almighty God to reveal his merits, a light, from Heaven was seen over his grave every night; till the neighbouring people who saw it, perceiving that he had been a holy man that was buried there, and inquiring who and whence he was, carried away the body, and interred it in the church, in the city of Boulogne, with the honour due to so great a person.
