Eisteddfod's Welsh rule could deter artist Josephine Sowden

A winning artist at last year's National Eisteddfod says she may not enter again because of a rule limiting the use of languages other than Welsh.
Josephine Sowden's video, The Lilies of the Field, won the £5,000 prize at the Lle Celf (Art Space), but her use of English words drew some criticism.
Any original words in art works must be in Welsh, although other languages can be used in quotations.
A festival spokesman said he hoped the rule would not deter artists.
