Earpwald, not long after he had embraced the Christian faith, was slain by one Ricbert, a pagan; and from that time the province was in error for three years, till Sigbert succeeded to the kingdom, brother to the same Earpwald, a most Christian and learned man, who was banished, and went to live in Gaul during his brother’s life, and was there initiated into the mysteries of the faith, whereof he made it his business to cause all his province to partake as soon as he came to the throne. His exertions were nobly promoted by Bishop Felix, who, coming to Honorius, the archbishop, from the parts of Burgundy, where he had been born and ordained, and having told him what he desired, was sent by him to preach the Word of life to the aforesaid nation of the Angles. Nor were his good wishes in vain; for the pious labourer in the spiritual field reaped therein a great harvest of believers, delivering all that province (according to the inner signification of his name) from long iniquity and unhappiness, and bringing it to the faith and works of righteousness, and the gifts of everlasting happiness. He had the see of his bishopric appointed him in the city Dommoc, and having presided over the same province with pontifical authority seventeen years, he ended his days there in peace.

At this time, the kingdom of the East Angles, after the death of Earpwald, the successor of Redwald, was [pg 172]governed by his brother Sigbert, a good and religious man, who some time before had been baptized in Gaul, whilst he lived in banishment, a fugitive from the enmity of Redwald. When he returned home, as soon as he ascended the throne, being desirous to imitate the good institutions which he had seen in Gaul, he founded a school wherein boys should be taught letters, and was assisted therein by Bishop Felix, who came to him from Kent, and who furnished them with masters and teachers after the manner of the people of Kent
