Duchesne in his Historiae Normannorum scriptores antiqui, at Paris in 1619. Another edition is in the Patrologia Latina, tome cxli, of J. P. Migne (Paris, 1844), but the best is perhaps the one edited by J. Lair (Caen, 1865). Dudo claims that Richard I of Normandy was sent by his father William I Longsword to learn the "Dacian" language with Bothon. Dudo stated in the same passage that the inhabitants of Bayeux more often spoke "Dacian" than "Roman" (i.e. Old French). Notes Edition and translation French Translation: Lair, Jules (ed.).
