The vision over, Tundale begged to be allowed to stay, but the Angel told him that he must return to the body. He further bade him remember what he had seen, that he might deliver it to the people of the world. He engaged Tundale to eschew evil in future, and promised to protect and counsel him. For several reasons, it seemed advisable to relate Tundale’s vision with some fulness of detail. In the first place, it can hardly be that a work which so soon acquired, and long maintained, an immense popularity throughout all Western Christendom, failed to exercise great influence in the way of fixing, if not of determining, the views generally held concerning the Otherworld. Further, as the work of an Irish author, written in the centre of Europe, and almost immediately adopted throughout the West; embodying, moreover, while continuing and enlarging, the ideas currently held by members of the Christian Church respecting the future life, and, at the same time, containing many elements of distinctly Irish, and even pagan, origin, it reveals beyond dispute the existence, the manner, and, partly, the extent of the contribution which the legend made to the development of modern literature, after quitting the soil upon which it had matured. The Vision of Tundale has many points in common with the _Fis Adamnáin_, _e.g._ the preference accorded to the martyrs and ascetics, the special provision made for the charitable sinners, the nine orders of Heaven, the episodes of the bridges and the Tree of Life, etc. Like Adamnán, Tundale expressed a desire to remain in Paradise, but was bidden return, and relate what he had seen. From a literary point of view, the work is decidedly inferior to the _Fis_; it is retrograde, too, in the absence of a definite scheme of the Otherworld; historically, however, it marks a forward step in the development of the purgatorial idea, of which, perhaps, it affords the most complete example which religious fiction contains, prior to its final perfection by Dante. It also prepares the way for the group of legends associated with St. Patrick’s Purgatory, for it introduces the idea of the Seer himself suffering the purgatorial pains, with a view to his own redemption; Tundale’s vision, however, contains no suggestion of a local purgatory in this world. In both these respects, he is followed by Dante, to some extent, though the comparatively slight annoyances endured by the latter during his ascent of the purgatorial mount--with the exception of the fiery wall, for which there was a special reason--were rather, so to speak, incidents of travel, necessitated by the nature of the country through which he had to pass, than sufferings inflicted on him for his purgation. In one respect, Marcus merits to be raised to a bad eminence among his kind: we have marked already, in the development of the Irish idea of the Otherworld, a growing tendency to accumulate horrors, and to elaborate and multiply painful details; but
