In the foregoing pages it has been attempted to trace, from its various sources, the progress of the legend which culminated in Dante’s _Commedia_. It did not form a part of this design to collect the corresponding traditions which abound in the folklore of many times and peoples, nor even to give an exhaustive account of the forms which the legend assumed in the several fields which have come within our purview; rather to confine our examination to those examples which may be regarded as its sources, or may have contributed to its transmission, or determined the form which it assumed in later stages of its development. We have seen that Dante’s poem had been led up to by a long series of predecessors, like it in theme, if in nothing else, and that it had already approved its fitness for a place in the world’s literature, by the success which it had achieved, in countless forms, among peoples of widely diverse stages of culture. We have also seen how the Irish Church, in its palmy days, developed a highly characteristic treatment of the theme, and while following, in the main, the accepted traditions of the mediæval Church, introduced certain modifications of a strongly individual and national type. Of this class the Vision of Adamnán has been selected for a specimen, as representing the highest level attained by the school to which it belonged, and as being the most important contribution made to the growth of the legend within the Christian Church prior to the advent of Dante.
