Twm o’r Nant was the pen name of the Welsh language dramatist and poet Thomas Edwards (January 1739 – 3 April 1810), also known as Tom of the Dingle. He was famous for his anterliwtau (interludes or short plays), which he performed mainly around his native Denbighshire.
Edwards was born in Llannefydd, Denbighshire (now in Conwy County Borough). When a child his parents moved to Y Nant Isaf (Welsh for Lower Brook), near Nantglyn, from which he took his pen name. Edwards had little formal education: he attended one of Griffith Jones' circulating schools where he learned to read, and attended a school in Denbigh for two weeks to learn English. However, he was eager to learn to write – he cadged writing paper and wrote with ink that he made from elderberries.
In 1749 Edwards joined a local company of touring actors who typically performed on an improvised stage such as a cart. He wrote seven interludes before he was twenty years old, all of which have been lost.
In 1763 Edwards married Elizabeth Hughes; the wedding was conducted by the poet-priest Evan Evans (Ieuan Fardd). The couple settled in Denbigh where Edwards worked hauling timber, performing in his interludes throughout North Wales, and selling printed copies of the interludes. After financial problems caused by the bankruptcy of his uncle for whom he stood surety, Edwards moved to South Wales where he again worked in timber haulage and for a time kept an inn in Llandeilo. He returned to North Wales in 1786 where he resumed his performances of interludes and became a stonemason. During 1808 he worked for William Madocks on the construction of the Porthmadog embankment.
Edwards' interludes commentate on the social evils of his day, frequently referring to unpopular taxes, greedy landowners, swindling lawyers and immoral clergymen. They form a link between the medieval and modern traditions of Welsh drama. Edwards also wrote and published ballads, of which about 200 remain (some as fragments). He wrote a short autobiography which was published in the periodical Y Greal in 1805.
