Edward,** keeper of the museum at Oxford, was a native of South Wales, the son of Charles Lhuyd, Esq., of Llanvorde. He was educated at Jesus College, Oxford, where he was created M.A. July 21, 1701. He was bred under Dr Plot, whom he succeeded as keeper of the Ashmolean museum, and had the use of all Vaughan's collection. With incessant labour and great exactness he employed a considerable part of his life in searching into the Welsh antiquities; had perused or collected a great deal of ancient and valuable matter from their MSS.; transcribed all the old charters of the monasteries that he could meet with; travelled several times over Wales, Cornwall, Scotland, Ireland, Armorica Bretagne, countries inhabited by the same people; compared their antiquities, and made observations on the whole; but died in July 1709, before he had digested them into the form of a discourse, as he intended, on the ancient inhabitants of this island. The untimely death of this excellent antiquary prevented the completing of many admirable designs. For want of proper encouragement, he did very little towards understanding the British bards, having seen but one of those of the sixth century, and not being able to procure access to two of the principal libraries in the country. He communicated many observations to Bishop Gibson, whose edition of the Britannia he revised; and published "Archologia Britannica," giving some account additional to what has been hitherto published of the languages, histories, and customs, of the original inhabitants of Great Britain, from collection and observations in travels through Wales, Cornwall, Bas Bretagne, Ireland, and Scotland, vol. i. Glosoffraphy, Oxford 1707," fol. He left in MS. a Scottish or Irish-English Dictionary, proposed to be published in 1732 by subscription, by Mr David Malcolm, a minister of the church of Scotland, with additions; as also the Elements of the said language; with necessary and useful informations for propagating more effectually the English language, and for promoting the knowledge of the ancient Scottish or Irish, and very many branches of useful and curious learning. Lhuyd, at the end of his preface to the Archologia, promises an historical dictionary of British persons and places mentioned in ancient records. It seems to have been ready for press, though he could not set the time of publication. His collections for a second volume, which was to give an account of the antiquities, monuments, &c., in the principality of Wales, were numerous and well chosen; but, on account of a quarrel between him and Dr Wynne, then fellow, afterwards principal of the college, and bishop of St Asaph, he refused to buy them, and they were purchased by Sir Thomas Seabright, of Beachwood in Hertfordshire, in whose library the greatest greatest part still remain, but so indigested, and written with so many abbreviations, that nobody can undertake to publish them. They consist of about 40 volumes in folio, 10 in quarto, and above 100 smaller, and all relate to Irish or Welsh antiquities, and chiefly in those languages. Carte made extracts from them about or before 1736; but these were chiefly historical. Sir John Seabright has given Mr Pennant 23 of Lluyd's MSS. Latin and English. Many of his letters to Llitter, and other learned contemporaries, were given by Dr Fothergill to the university of Oxford, and are now in the Ashmolean museum. Lluyd undertook more for illustrating this part of the kingdom than any one man besides ever did, or than any one man can be equal to.
