The Trinity as Taper: A Welsh Allusion to Langland.
Finds an allusion to WL’s comparison of the Trinity to a taper (B. 17.205-13 [Schmidt], C. 19.167-75 [Pearsall]) in the poem O gyfarch yn y gafell by Dafydd ab Edmwnd (fl. 1450-90). Whereas various homiletic materials compare Christ to a taper, WL and Dafydd are unique in the metaphor of the burning candle for the Trinity.
