Welsh Triads
Also known as: Trioedd Ynys Prydein, Triads of the Island of Britain, Welsh Triads
A medieval Welsh catalogue of lore arranged in triads that preserves names, events, and motifs from Brittonic legend, early Arthurian tradition, and the Mabinogi cycle.
Description
The Welsh Triads (Trioedd Ynys Prydein) organize traditional lore into memorable sets of three—heroes, battles, marvels, omens, and moral exemplars—serving as mnemonic scaffolds for poets and storytellers. The collections preserve a cross-section of Brittonic tradition: figures from the Mabinogi stand beside early Arthurian companions and northern British heroes. While concise, the triads encode networks of relationships, variant episodes, and rankings of fame or infamy, hinting at lost narratives and linking extant tales. Their triadic form reflects bardic pedagogy and facilitates oral retention, while the surviving manuscripts attest to continued curatorial activity by medieval scribes.
Historiography
The triads survive in several medieval Welsh manuscripts, notably Peniarth collections and the White Book of Rhydderch (c. 1350) and Red Book of Hergest (late 14th century). Editorial traditions differentiate earlier cores from later accretions and variant groupings. Modern critical study was consolidated by Rachel Bromwich, who collated manuscripts and established a standard numbering while identifying spurious 18th-century additions associated with Iolo Morganwg. The triads have informed scholarship on early Arthurian material and the transmission of Welsh narrative tradition.
Date Notes
Triadic materials likely circulated orally before being compiled in medieval manuscripts such as Peniarth 16 and the White and Red Books.
