The mission of St. Augustine, backed with the royal countenance of Ethelbert, had, though not completed, done much towards conversion; but on their death practically the whole of the Christian territory, excepting Kent, relapsed into heathenism, and to such an extent that Augustine's successor, Laurentius, was on the point of giving up the whole mission and taking refuge in Gaul. Not until 625 did a mission again venture forth from the Kentish kingdom, and then their tentative efforts were rendered abortive by the battle of Hatfield in 633, which for a while seems to have crushed all hope at Rome. But a couple of years later an independent missionary, Birinus, was consecrated in Italy, and was sent by the people to make fresh attempts to break down the barriers of heathenism in England. Through his influence Cynegils became the first Christian king of the West Saxons. To inaugurate his conversion the monarch decided to establish a bishopric, and immediately began to collect materials for building, at his capital of Winchester, a cathedral, which was eventually constructed by his son Cenwahl in 646. The Danes in 867 broke up the establishment, and the year following, secular priests were substituted. They remained till 963, when Ethelwold, by command of King Edgar, expelled them to make room for the monks of the Benedictine Order from Abendon. They enjoyed uninterrupted possession, and were richly endowed with royal donations, as the dissolution revealed the extent of its revenue. Henry VIII. then refounded it for a bishop, dean, chancellor, twelve prebendaries, and other subordinate officers. The Cathedral was first dedicated to St. Amphibalus, then jointly to St. Peter and St. Paul, and afterwards to St. Swithin, once bishop here. With Henry VIII.'s régime the title was altered to the Holy and undivided Trinity. The church of Cynegils having become entirely ruined, a new cathedral was commenced in 1073-98 by Bishop Walkelyn. The two Norman transepts and the low central tower, as also the very early crypt, still exist. The church is a spacious, massive, and splendid cruciform building of Norman architecture with subsequent additions in the Gothic style. The whole of the Norman nave was demolished and re-erected on a far grander scale by William of Wykeham at the end of the fourteenth century, though not quite completed till after his death. The choir was much restored in the fourteenth century, whilst it underwent considerable alteration by Bishop Fox from 1510 to 1528. Here is the tomb of William II. A great feature is the magnificent reredos behind the altar. It extends the full width of the choir, with two processional entrances pierced through its lofty wall, and covered with tier upon tier of rich canopied niches. They once contained colossal statues. Behind this reredos there is a second stone screen, which enclosed the small chapel in which stood the magnificent gold shrine studded with jewels. It contained the body of St. Swithin,
