WILLIAM OWEN, an eminent Welsh scholar, was born in the parish of Llanfihangel-y-Pennant in Merionethshire in 1759. All his energies from an early period were devoted to the advancement of his native language. On removing to London at the age of seventeen, he began a series of exertions for preserving and illustrating the ancient Welsh literature. He assisted Owen Jones in editing the poems of Dafydd-ap-Gwilym and of Llywarch Hen, and in compiling the Mynegian Archaeology of Wales. At the same time he was producing several works on his own account. His great work, The Welsh and English Dictionary, appeared in 1793-1803; and his Cambrian Biography, in 1803. Scarcely less indefatigable were his labours in behalf of his mother-tongue, after he had succeeded in 1806 to a considerable estate near Denbigh. He wrote Welsh translations of Milton's Paradise Lost, Heber's Palestine, and other English poems. He was preparing for the press a treatise on The Ancient Romances of Britain, when he died in 1835 at Dolwydlay-Cay, a house at the foot of Cader Idris.
