this period in western England. However, most temples seem to have been replaced eventually by Christian churches on the same site or nearby. "Celtic" churches or monasteries seem to have flourished during this period in the British areas, such as that at Glastonbury, though mostly not until the 6th century; but the "Saxons" were pagan. This reinforced a great antipathy between the peoples. Many Roman cemeteries continued into much later times, such as that at Cannington, Somerset. In the east, there was a gradual transition among the pagan Saxons from cremation to inhumation. Although the arrival of Saint Augustine is traditionally seen as the significant Christianising event for the Saxons, a bishop had already arrived in Kent with the king's Merovingian wife. Other Saxons remained pagan after this time. In 429, a British Deacon, Palladius, had requested support from the Pope in Rome to combat Pelagianism. Bishops Germanus and Lupus of Troyes were sent. Germanus, a former military commander, is reported to have led the British to the "Hallelujah" victory, possibly in Wales or Herefordshire. Germanus is said to have made a second visit to England later. Participation by a British bishop at a synod in Gaul demonstrates that at least some British churches were in full administrative and doctrinal touch with Gaul as late as 455. In the north, Whithorn is said to be the earliest church in Scotland, being founded in 397 by Saint Ninian. Coroticus (or Ceretic) was a apostate Pict king who was the recipient of the letter from Saint Patrick. His base may have been Dumbarton Rock on the River Clyde, and his descendant Rhydderch Hael is named in the Life of Saint Columba. Rhydderch was a contemporary of Áedán mac Gabráin of Dal Riata and Urien of Rheged in the late 6th century, as well as of Æthelfrith of Bernicia. Unlike Columba, Kentigern, the supposed apostle to the Britons of the Clyde and alleged founder of Glasgow, is a shadowy figure. Anglo-Saxon migration Linguistic evidence Linguistics is useful in the analysis of culture, and to an extent political associations. Bede in Historia ecclesiastica gentis Anglorum (completed in 731) wrote that "currently, [there are in Britain] the languages of five peoples, namely that of the Angles (English), the Britons (Brittonic), the Scots (Gaelic), the Picts and the Latins" (HE 1.1). A review of the changes in the Brythonic language during this period is given by
