Sinners that have been induced to see the errors of their ways and to amend, find the bridge narrow and difficult at first, but easy afterwards, while those fall off who have persevered in evil. We thus have only three of the usual four categories which frequently occur in Irish eschatology, as in the Book of Enoch: the _boni valde_, the _boni sed non valde_, and the _mali valde_. However, the _mali sed non valde_ are represented, approximately, by those spirits of mingled qualities, and those sinners that are redeemed by their good works, who are dealt with specially in the sequel. The torments meted out to evildoers are of the usual description, though represented with that increasing fulness and terror which had been perceptible for some time previously in the Irish visions, or _Imrama_, the result, apparently, of increased familiarity with the Continental writers of this kind, who, so early as the Apocalypses of St. Peter and St. Paul, had devoted much ingenuity to this horrible branch of their subject. We may also perceive an attempt at a more accurate classification of crimes and punishments; in this respect, too, those Apocalypses display more method than the visions of subsequent writers. The classification adopted by our author, which would seem to be his own, contains indications both of his nationality, and of his acquaintance with foreign literature. Four categories of evildoers are enumerated, in which, although they exhibit nothing of Dante’s scientific precision, a certain system is apparent, in spite of the several classes overlapping to a certain extent. In chapter 25 fratricides and sacrilegious persons are dealt with, including fraudulent Erenachs--the guardians of the Church’s temporalities--who had abused the considerable powers which the tribal constitution of the Irish Church had given them. The class described in chapter 27 comprises, for the most part, those guilty of various kinds of dishonesty or violence, though some of them, such as false judges, sorcerers, and teachers of heresy, would seem to belong rather to the two following classes, the one of which comprises renegade ecclesiastics and heresiarchs (chapter 28), while the other, and last deals with an apparently heterogeneous collection of crimes, all of which, however, will be found to involve, somehow, a breach of faith on the part of the offender.
