Rabin, Andrew, “Preventive law in early Ireland. Rereading the Additamenta in the Book of Armagh”, North American Journal of Celtic Studies 2:1 (2018): 37–55.  
This article argues that the so-called Additamenta, found on ff. 16r–18v of the Book of Armagh, may have functioned as a form of preventive law. Reading the Additamenta in this fashion suggests that the evidence they adduce to legitimize Armagh's property rights reflects those categories of claims thought most likely to prevail should the foundation's landholdings fall into dispute. As an archive of documents that both preserved and shaped institutional memory, they provided a historical frame that limited the possibility of challenges to Armagh's standing or, if those challenges did come to trial, shaped the court's perception to the foundation's benefit. Consequently, even if these documents do not necessarily reflect an ongoing charter tradition, we may still use them as case studies revealing one way in which early Irish landowners—especially those associated with ecclesiastical foundations like Armagh—utilized text and narrative to influence the progress of legal disputes.

In the Book of Armagh, on f 159v, we find a lozenge of text which suggests a division system for the text of the New Testament’s Book of the Apocalypse. This short text, which is also found in the Metz Bible, identifies fourteen moments in the Apocalypse in a manner very similar to the way a set of capitula identifies passages within a text while dividing it into sections-and this text has traditionally been studied as one more set of textual divisions for this biblical book. However, closer examination of the text, combined with a comparison with other sets of capitula from biblical codices and summaries in exegetical handbooks suggest this text neither sections the book efficiently nor does it provide an introduction to its content. Rather, the numbered list of items proceeds visually through the book, offering the reader a guide to imagining the visions directly while knowing the narrative account of those visions is to be found in the biblical book’s text.

Were we dependent on the pre-Norman Irish annals alone, we should know nothing of the early history of the church of Drumlease, near Dromahair, Co. Leitrim. Like many of the other churches of Connacht, Drumlease suffers from the comparative neglect of the western province's early ecclesiastical history on the part of the surviving collections of annals. The ‘Patrician’ texts in the Book of Armagh, however, provide a snap-shot of Drumlease in the later seventh and eighth century, indicating that it was a church of considerable significance in north Connacht at that time. This study comprises two parts. The first, by Colmán Etchingham, introduces the references to Drumlease in the Book of Armagh and examines in detail the relevant passages of the eighth-century text known as the Additamenta. The second part, by Catherine Swift, places Tírechán's reference to Drumlease in the broader context of that seventh-century clergyman's portrayal of the Patrician churches of Connacht in general.
