The "letters of exhortation" which he is said to have addressed to Mellitus, Archbishop of Canterbury, and to Justus, Bishop of Rochester, are no longer extant, but certain other letters of his have been preserved.
De "brev med förmaningar" som han sägs ha skrivit till Mellitus, ärkebiskop av Canterbury, och till Justus, biskop av Rochester, finns inte bevarade, men några andra brev finns fortfarande kvar.
