“ Genuine popul.nr legends possess a high literary value, and must always be received with interest, although they 
may aspire to no greater elevation than that of a mere nursery tale ; and amongst the most valuable which modern 
research has brought to light, must he placed ‘ Lady Guest’s Mabinogion.’ The tales are curious additions to the 
stock of undoubted Celtic remains. It is interesting to trace in their supernatural machinery the close connexion 
which subsists between the marvels of the East and of the West; and to find not only some of the wonders, but 
actually some of the incidents, which amused our childhood in the ‘Arabian Nights,’ told with earnest faiUi and 
wild poetry, by the Welsh bards of the twelfth century.” — Athen.s;um.
