A named protector can be kept away
The sons of Uisnech accept return because trusted men guarantee their safety. Conchobar's contrivance separates Fergus from them without making the announced protection meaningful in practice. The guarantors' subsequent revenge confirms the seriousness of the violated undertaking, but does not save its beneficiaries. A promise can organize trust while still depending on people being able and willing to enforce it.

An exact agreement with a destructive purpose
Lugh's compensation demand is publicly guaranteed, yet its details are explained only after the brothers accept. The full fine must be delivered, while the claimant uses forgetting to strip away the resources that could protect the travelers. The problem is not simply that someone breaks a promise. The narrative also asks what happens when formal compliance serves an intentionally unforgiving design.

A duty exploited by a deceiver
The woman at Slieve Cullinn invokes Fionn's obligation to help women in distress, directing him into the enchanted lake. Joyce uses the language of gesa for that binding demand. It should not be treated as legally identical to the named sureties in Deirdre's story. The useful comparison is narrower: conduct meant to display honor becomes vulnerable when another person controls the conditions.

- Period / witness
- Medieval Irish prose and verse preserved in medieval and early modern manuscript witnesses; Leahy translation 1905–1906. Two comparisons use Joyce’s separately adapted tales.
- Recording context
- This entry concerns the literary version named in its passages, transmitted by Christian-era Irish manuscript culture and translated by A. H. Leahy. Legendary settings are not dates of composition or evidence for a single pre-Christian canon. Tuireann and Slieve Cullinn are read in Joyce’s 1920 print witness, not treated as the same legal genre.
A recording location is not necessarily a story’s origin. Dates of texts, copies, and translations answer different questions.
