The late scholar Brynley Francis Roberts, who died in 2023 aged 92, described the function of triads in early Welsh culture in this way:
The triads are a classification technique devised by the guardians of Welsh tradition to facilitate the recall of this material by systematizing it and associating three characters or episodes with one another on the basis of a feature common to all three: the triad would then have a formulaic title, ‘the three [epithets, or adjectives] of the Island of Britain . . .’ 1991: 80-1.
The Trioedd Ynys Prydein, commonly referred to as the Welsh Triads or with the acronym TYP, were possibly compiled in the 11th or 12th centuries, but the earliest surviving version in manuscript dates from the mid 13th century; the so-called Later Version survives in two subsequent collections (The White Book of Rhydderch, and The Red Book of Hergest) from the mid and late 14th century, and in sundry other texts.¹
Additionally, Roberts noted that “the Welsh Arthurian world underlies the allusions to legends of Arthur found in Trioedd Ynys Prydein (The Triads of the Island of Britain),” a feature which has long attracted the attention of those whose first language isn’t Welsh.
But there are also the Arthurian triads from a later source, brought together by a certain Edward Williams in the late 18th century. However, these are often regarded as of questionable value, the reason being that Williams is better known by his bardic name, Iolo Morganwg – that is, Edward (Iorwerth) of Glamorgan. And Iolo is known to have forged or invented some of the material he pretended was traditional.
