A full-length marble statue of him was erected in that court in 1701, and it now stands near the school buildings of the new hospital. A portrait of Clayton, by Jonathan Richardson, hangs in the governor's hall at the counting-house of that institution, and in the livery room of the Drapers' Company is a three-quarter length of him by Kneller, painted in 1680. The speech by Clayton, as lord mayor elect, to the citizens on 29 Sept. 1679 was printed in that year; it was strong on behalf of protestantism.

CLAYTON, ROBERT (1695–1758), Irish bishop, born at Dublin in 1695, was a descendant of the Claytons of Fulwood, Lancashire, whose estates came to him by inheritance. He was the eldest of eight children of Dr. Robert Clayton, minister of St. Michael's, Dublin, and dean of Kildare, and Eleanor, daughter of John Atherton of Busie. Zachary Pearce [q. v.] privately educated him at Westminster School. He entered Trinity College, Dublin, became B.A. 1714, a fellow the same year, M.A. 1717, LL.D. 1722, and D.D. 1730. He made the tour of Italy and France, and on his father's death in 1728 came into possession of a good estate and married Catharine, daughter of Lord Chief Baron Donnellan. He gave his wife's fortune to her sister, and doubled the bequest, under his father's will, to his own three sisters.
A gift of 300l. to a distressed scholar recommended to him by Samuel Clarke (1675-1729) [q. v.] brought him the intimate friendship of Clarke. Clayton embraced Clarke's doctrines and held to them through life. Queen Caroline, hearing from Dr. Clarke of Clayton's remarkable beneficence, had him appointed to the bishopric of Killala and Achonry in 1729-1730. In 1735 he was translated to that of Cork and Ross, and in 1745 to that of Clogher. His first literary production was a letter in the 'Philosophical Transactions,' August 1738, on a French refugee, in Cork, suckling a child, with an account of a remarkable skeleton. In 1739 he published 'The Bishop of Corke's Letter to his Clergy,' Dublin, 8vo, and 'A Sermon preached before the Judges of Assize,' Cork, 4to, and in 1740 ' The Religion of Labour,' Dublin, 4to, for the Society for Promoting English Protestant Schools in Ireland. In 1743 he published ' A Replication . . . with the History of Popery,' &c., Dublin, 4to, directed against the author of 'A Brief Historical Account of the Vaudois.' In 1747 appeared 'The Chronology of the Hebrew Bible vindicated ... to the Death of Moses,' London, 4to, pp. 494. In 1749 he published ' A Dissertation on Prophesy . . . with an explanation of the Revelations of St. John,' Dublin, 8vo; reprinted London, 8vo. This work aimed at reconciling Daniel and Revelation, and proving that the ruin of popery and the end of the dispersion of the Jews would take place in A.D. 2000. Two letters followed, printed separately, then together, 1751, London, 8vo, 'An Impartial Enquiry into the Time of the Coming of the Messiah.' In 1751 appeared the remarkable work written by him, though often asserted to be that of a young clergyman of his diocese, 'Essay on Spirit . . . with some remarks on the Athanasian and Nicene Creeds,' London, 1751, 8vo. This book, full of Arian doctrine, led to a long controversy. It was attacked by William Jones, Warburton (who described it as 'the rubbish of old heresies'), Nathaniel Lardner, and many others. The Duke of Dorset, the lord-lieutenant, refused on account of this work to appoint him to the vacant archbishopric of Tuam. Several editions appeared in 8vo and 12mo, 1752, 1753, and 1759. In 1752 a work having appeared called ' A Sequel to the Essay on Spirit,' London, 8vo, Clayton published 'The Genuine Sequel to the Essay,' &c., Dublin, 8vo. His next work was 'A Vindication of the Histories of the Old and New Testament, in answer to the Objections of . . . Bolingbroke,' pt. i., Dublin, 1752, 12mo. The same year he was made fellow of the Society of Antiquaries, having some years before been elected a fellow of the Royal Society. In 1753 he published 'A Journey from Grand Cairo to Mount Sinai, and back again. In Company with some Missionaries de propaganda Fide,' &c., translated from a manuscript which had been mentioned by Pococke in his 'Travels.' The chief interest lay in the account of the supposed inscriptions of the Israelites in the Gebel el Mokatab. The work was addressed to the Society of Antiquaries, and the author offered to give 500l., spread over five years, to assist an exploration in Mount Sinai, but the society took no steps in the matter. Mr. Wortley Montagu, however, was induced to visit the spot and give an account of the inscriptions. The same year Clayton published 'A Defence of the Essay on Spirit,' London, 8vo. His next
