Corpus Iuris Hibernici
The Corpus Iuris Hibernici is a six-volume collection of the sources for the study of early Irish law edited by D. A. Binchy. It presents a transcription of the manuscripts relevant to this study.
The CIH was intended as a replacement for the Ancient Laws of Ireland, a series which relied on more limited sources and suffered from unscholarly and unreliable editorial work. Prior to Binchy's work, the best sources for early Irish law were the unpublished transcripts of John O'Donovan and Eugene O'Curry, which circulated in scholarly libraries in a few copies. Because of this, scholars like Rudolf Thurneysen were forced to rely on O'Donovan and O'Curry to correct errors in the published version, but nonetheless referred to the Ancient Laws of Ireland in their published footnotes for reasons of accessibility.
Though the CIH was highly rated for its editorial work, it received some criticism for its difficulty of use. Critics pointed out that it had no translations, no explanatory notes, few cross-references, and a table of contents which only listed the manuscripts transcribed. Myles Dillon called the work "austere". T. M. Charles Edwards suggested that, rather than produce an edition of the manuscripts, a scholar of Binchy's stature could well have produced a critical edition of the texts themselves. Fergus Kelly's Guide to early Irish law and Liam Breatnach's Companion to the Corpus iuris hibernici took on the task of identifying, describing, and making comprehensible these texts. Breatnach has identified 102 individual texts in the CIH and has incorporated elsewhere published texts into the corpus.
