Among the works of authority referred to by mediæval writers the Revelations of Methodius long held a prominent place. Its popularity continued even into comparatively modern times, for from the year 1475 printed editions of the text appeared at frequent intervals. Sackur, its latest editor, who has prepared a critical version of the work, goes so far as to credit it with an influence second only to that of the canonical books and the Church Fathers. It is the purpose of the present study, first, to investigate the influence of this work upon Middle-English writers, discovering, if possible, to what extent and in what version, they used Methodius; and furthermore, to publish, as evidence of the popularity of the Revelations, a Middle-English metrical translation, which has been preserved in a single ms. Before taking up this phase of the influence of Methodius, however, it will simplify the discussion to summarize briefly what sort of material the Revelations contains, and what is known of its author and its origin.
