Chronicles and Original Histories.

Chronicles of the Crusades, being contemporary narratives of the crusade of Richard Coeur de Lion, by Richard of Devises and Geoffrey de Vinsauf; and of the Crusade of Saint Louis, by Lord John de Joinville. London: Henry G, Bohn, 1848. —Quoth the librarian, “The chronicle here attributed to Geoffrey de Vinsauf is now shown to be, in large part, a Latin translation of Ambrose’s L’estoire de la guerre sainte, probably made by Richard, canon and prior of Holy Trinity, London, about 1200. cf. Gross, Sources and Literature of English History.”
