The title Trecheng Breth Féne "A Triad of Judgments of the Irish", more widely known as "The Triads of Ireland", refers to a miscellaneous collection of about 214 Old Irish triads (and some numerical variants) on a variety of topics, such as nature, geography, law, custom and behaviour. Its compilation is usually dated to the ninth century.

The following example is Triad 91:
The use of the triad form (arrangement into threes) to encapsulate certain ideas is neither distinctively Irish nor Celtic, but can be widely attested in many societies over the world, in part owing to its usefulness as a mnemonic device. It does appear to be particularly popular in the literatures of Celtic-speaking areas, one notable other example being the later Welsh collection Trioedd Ynys Prydein ("Triads of the Isle of Britain"). Beyond the particular form, however, there is nothing to suggest a shared literary tradition. Although triads can be pointed out in both Irish and (again later) Welsh law texts, they are the rule in neither as other numerical forms are usually preferred. Kuno Meyer proposed that the practice was inspired from the Old Testament, which however, offers very few examples. Fergus Kelly concludes that "[t]he case for a special Celtic cult of threeness is unproven, as is the attempt by Meyer and other scholars to establish a biblical origin."
