From the Britons the city in 577 was captured by the Saxons. They called it Gleauanceaster, which exists to this day under the contracted form of Gloucester. At that time it was included in the kingdom of Wessex, and was afterwards annexed to that of Mercia. In the meanwhile tradition says that a bishop's see was founded at Gloucester in the second century. Lucius, the first Christian king of Britain, is held to be the founder, and is also supposed to have been buried in the Church of St. Mary de Lode of this city. With all respect to tradition, this can only be accepted with reservation. If true, the present church of St. Mary de Lode deserves far greater recognition than it receives. Though evidently an old foundation much restored, it can hardly lay claim to such antiquity. In all probability a temple to some Roman deity existed, which, by conflicting accounts of historians, gave rise to the supposition of an early established see. Though there is proof that Christianity existed during the Roman occupation of England, it seems more likely that, after their general exodus from the island in 418, a diocese, if any, was soon after established at Gloucester, over which Eldad presided in 490. This first bishopric, on the subversion of the country by the Anglo-Saxons, must have become extinct; for the next we hear of it is when, as part of the kingdom of Mercia, the entire county of Gloucester is included in the diocese of Lichfield at the time of the introduction of Christianity. However, the first authentic evidence of monasticism appears in the year 679, when the holy brethren founded their establishment. Under the auspices of Wulfhere, then King of Mercia, this priory was dedicated to St. Oswald, and in the same year was annexed to the newly established see of Worcester. It afterwards became the abbey. The city's importance in the same year was considerably increased by the royal patron. The King's brother and successor, Ethelred, nevertheless, completed the ecclesiastical building, which some contend was a nunnery. This the Danes destroyed. It was then refounded for the reception of secular priests in 821, by Bernulf, King of Mercia.
