I didn't say there was no Welsh literature, just that it is trivial in breadth and depth next to work originated in English languages.

When was the last time you read Beowulf in the original? I think Old English is probably as unintelligible as Welsh to the average English reader. At least in Welsh they'll recognise all the letters, even if they get the sounds wrong...
