Two very significant eisteddfodau were held at Denbigh in 1824 and 1828, under the auspices of Cymdeithas Cymmrodorion Powys. In 1824, as this picture shows, the prize for playing the harp was this miniature silver model of a harp. It's very interesting, because it's obvious that this particular prize was modelled on the famous model of a harp kept today at Plas Mostyn, and which was won by the harpist at the second Caerwys eisteddfod, back in 1567. It is worth remembering that, as far as we know, the prizes at those early eisteddfodau were made to be worn. And the silver harp given in 1824 in Denbigh obviously has a link with that earlier prize, which makes it very interesting to say the least.
