The oldest known copy, in four folio volumes, of which the date and origin are unknown, but which is certainly almost entirely Walafrid's work, gives us his method.
Walafrid's poetical works also include a short life of St Blaithinaic, a high-born monk of Iona, murdered by the Danes in the first half of the 9th century; a life of St Mammas; and a Liber de visionibus Wettini.
Many of Walafrid's other poems are, or include, short addresses to kings and queens (Lothair, Charles, Louis, Pippin, Judith, &c.) and to friends (Einhard, Grimald, Hrabanus Maurus, Tatto, Ebbo, archbishop of Reims, Drogo, bishop of Metz, &c.).
For a bibliography of Walafrid's historical works, and of writings dealing with them, see Potthast, Bibliotheca hist.
Walafrid's works are published in Migne's Patrologia Latina, vols.
