Bechbretha

[4]: 12  Ten other manuscripts (including British Library, MS Egerton 88) and O'Davoren's Glossary offer fragments of or quotations from the Bechbretha (of varying length).

[4]: 8–13 D. A. Binchy proposed that the Irish legal texts Bechbretha and Coibes Uisci Thairdne ("Kinship of conducted water", a tract on watermills) were by the same author.

Thomas Charles-Edwards and Fergus Kelly follow Binchy in this hypothesis, and further propose that Bretha im fhuillema gell ("Judgements concerning pledge-interests") was a work from the same school as the author of the above two texts.

Questions about the swarming of hives onto others' land, which he tries hard to fit into the existing law of animal trespass, concern him much more than injuries to persons by bees.

Early Irish law very rarely gives cases involving genuine historical personages (preferring to invoke mythical or Biblical stories).
