The fourth bishop in succession to the "Mellifluous Mellitus" was Erkenwald, "Light of London," _Christi lampas Aurea_ (675-693). It is said that he was son of Offa, the East Saxon king, who remained "paynim," but Erkenwald "changed his earthly heritage for to have his heritage in heaven; ... and whatsomever he taught in word he fulfilled in deed." He founded the monasteries of Barking and Chertsey. While he was bishop he used to preach about the city from a cart, and once, when a wheel fell off, the cart went forward without falling, "which was against reason and a fair miracle." He died at Barking, and the monks claimed his body, but "a chapter of Paul's and the people" said it should be brought to London. As they carried him to his own church there was a flood, but the waters of the Yla (Lea) were divided and a dry path given to the people of London, "and so they came to Stratford and set down the bier in a fair mede full of flowers, and anon after the weather began to wax fair and the people were full of joy." And, after, they laid and buried the body in St. Paul's, to the which he hath been a special protection against fire, nd time was when he was seen in the church with a banner fighting a fire which threatened to burn the whole city, and so saved and kept his church.[177] The shrine of Erkenwald remained from this time till the Reformation the palladium of the city. [Illustration: FIG. 30.--TOMB OF KING ETHELRED IN OLD ST. PAUL'S.] In Saxon charters the church is styled "St. Paules mynstre on Lundene," and the full invocation appears to have been _Beati Pauli Apostoli Gentium Doctoris_, which in itself probably explains the choice of it for a mission church. Like the church which Augustine built at Canterbury, it would have been "planned in imitation of the Great Basilica of Blessed Peter." Such a basilica of considerable size is still to be seen at Brixworth, Northamptonshire. It would have had a narthex, a nave with "porticoes" or aisles, and beyond the great arch a presbytery and apse. In front would have been an atrium.[178]
