This closes the first era in the history of the church: the old _ecclesiola_ of Didan and his daughter was gutted by the fire, and its roofs and furniture destroyed. Indeed, until lately it was held that the whole building was of wood, and perished therefore with the tower and roof, no vestige of it remaining for later times. But the recent investigations of Mr. J. Park Harrison, an archaeologist of remarkable devotion and insight, have proved that the east wall of the eighth century church, with two of its primitive arches, still remains, a venerable relic of times past, as part of the wall of the cathedral; while the foundations of the three apses, into which the three low arches once led, have been discovered in the garden to the north-east of the church (see pp. 33, 34). So did Anthony à Wood, when in the seventeenth century he wrote of "the antientist buildings" as "on the east and north side of the church," speak more truth than even he himself was aware. After the slaughter of St. Brice's Day, King Ethelred made a vow that he would rebuild St. Frideswide's church. And well did he keep it; if in 1004 he built the splendid church which forms the main part of the cathedral as we know it to-day, sparing the more sacred part of the rude old building, it may be, because of the veneration in which everything connected with St. Frideswide was held. His charter contains the following sentence:-- "In the year of our Lord 1004, in the 2nd indiction, and in the 25th year of my reign, according to the disposal of God's providence, I Ethelred ruling over the whole of Albion, have with liberty of charters by royal authority and for the love of the Almighty, established a certain monastery situated in the city which is called Oxoneford, where the body of St. Frideswide reposes."
