Video & Text Work inspired by the important role of darkness in early Irish Literary technique :

"The deliberate use of enigmatic speech, too, is very well attested. In early Irish literature, the poetic rhetoric is described as having the qualities duibhe ('blackness' in the sense of obscurity), dorchatu ('darkness' in the sense of being mysterious) and dlúithe ('compactness'). The darkness of the poets' language is particularly stressed, and one early text poses the question 'where is poetry?' and then gives the answer 'in darkness' (i ndorchaidhéta)."
