The Greatest Ever Faker

He was a 19th century historian, poet and activist.

He founded the modern Eisteddfod – at a gathering atop London's Primrose Hill – uncovered medieval poems, an ancient alphabet and numerous manuscripts that stand as a lodestone of Welsh literary culture and decisively shaped modern Wales's idea of itself.

The thing is: it was mostly fiction - lies and forgeries.

Gareth Gwynn sets out on the trail of Ned of Glamorgan, aka Iolo Morganwg, to find out whether a modern Welsh man can really be an honest Welshman when his national traditions are based on falsehood.

Along the way he can't resist the temptation to create a few traditions of his own, leading down some blind and dangerous philosophical alleys.
