The Celtic-speaking world

Few riddles are attested in medieval Celtic languages, though this depends on how narrowly a riddle is defined; some early medieval Welsh and Irish juridical texts have been read as being riddles. One undisputed riddle is attested in medieval Welsh, an elaborate text entitled 'Canu y Gwynt' ('song of the wind') in the fourteenth-century Book of Taliesin probably inspired by Latin riddles on the same theme. However, this record is supplemented by Latin material, apparently from a Brittonic cultural background in North Britain, about Lailoken: in a twelfth-century text, Lailoken poses three riddles to his captor King Meldred.

The earliest riddles attested in Irish are generally held to be found in a short collection from the fifteenth-century Book of Fermoy. However, other forms of wisdom contest do occur in Irish literature, such as The Colloquy of the Two Sages, first attested in twelfth-century manuscripts, and in one such contest, in Imthecht na Tromdaime, first attested in the fifteenth century, at least one riddle is arguably posed.

Even research on the post-medieval Celtic-speaking world has yielded a "comparatively meagre corpus".
