lieutenant, and to the Duke of Manchester. He died in Dublin on 30 April 1859, and was buried on 3 May in Chapelizod churchyard.
Besides the works noted and many separate sermons and tracts, O'Sullivan wrote: 1. 'A Guide to an Irish Gentleman in his Search for a Religion,' Dublin, 1838; in defence of the established church, upon the publication of Moore's 'Travels of an Irish Gentleman in Search of a Religion,' 2 vols. London, 1833. It was answered anonymously in 'A Lanthorn for the Rev. Mortimer O'Sullivan's Guide to an Irish Gentleman in his Search for a Religion. From the Latin and German of Dr. Martin Luther,' Dublin, 1833. 2. 'The Case of the Protestants of Ireland stated, with Notes,' London, 1836. 3. 'Of the Apostasy predicted by Saint Paul,' pt. i. Dublin, 1841; pts. i. and ii. together, Dublin, 1842. 4. 'Theory of Developments in Christian Doctrine applied and tested,' London and Dublin, 1846; a reply to Cardinal Newman's 'Apologia.' 5. 'The Hour of the Redeemer,' a series of discourses preached in the chapel of Trinity College, Dublin, 1853.
O'Sullivan, Samuel (1790–1851), divine, elder brother of the above, born at Clonmel on 13 Sept. 1790, was educated with Mortimer at the Clonmel endowed school; attended protestant services with his school-master, and was powerfully attracted by the liturgy. When he obtained a scholarship at Trinity College, Dublin (1814), he was entered as a member of the church of England. He graduated B.A. in 1818, and M.A. in 1825. He was an active member of the university historical society, and carried off the medal for the best speaker in debates. Taking holy orders in the established church, he was first curate of St. Catherine's, Dublin, and at the same time chaplain of the Marshalsea, Dublin. In 1827 he succeeded Dean Le Fanu as chaplain to the Royal Hibernian Military School in Phoenix Park. His life was chiefly devoted to literary pursuit*. His first work, 'The Agency of Divine Providence manifested in the principal Transactions, religious and political, connected with the History of Great Britain from the Reformation to the Revolution in 1688,' Dublin, 1816, displayed a philosophic temper remarkable in a man of twenty-five. He contributed regularly to 'Blackwood's Magazine' and to 'Fraser's.' Some of the earliest papers in the 'Dublin University Review and Quarterly Magazine,' Dublin, No. 1, January 1833, were from his pen. He died on 6 Aug. 1851, and was buried on the 9th in the churchyard at Chapelizod, Dublin. His wife, with a son, Henry R. M. O'Sullivan, and a daughter, survived him. At the time of his death he had completed the 'Catechism of the United Church of England and Ireland explained and confirmed, with References to Holy Scripture,' Dublin, 1850. A volume of 'Remains, containing articles left by him in manuscript, was published by the Rev. J. C. Martin, D.D., and Mortimer O'Sullivan, Dublin, 1853, 3 vols.

O'SULLIVAN or O'SULLIVAN-BEARE, PHILIP (1590?–1660?), historian, born about 1590, son of Dermot O'Sullivan and nephew of Donall O'Sullivan-Beare [q. v.], lord of Dunboy, was in 1602, while still a lad, sent by his uncle to Spain, where, after the fall of Dunboy, he was joined by his father and his family. He was educated at Compostella, became a soldier, and served on board the Spanish ships of war. In 1619 he was in the squadron appointed to guard the treasure-fleet on its approach to Cape St. Vincent from the Barbary pirates, who were also on the look-out for it, and wrote an interesting account of the service to his old tutor (Compendium, edit. 1621, ff. 270–9). His military life was, however, not very noteworthy: his predilection was for literature, and to that he principally devoted himself. His most important work was the 'Historiæ Catholicæ Iberniæ Compendium' (Lisbon, 4to, 1621), an octavo edition of which, edited by Matthew Kelly [q. v.], was published at Dublin in 1860. The most valuable part of it is the history of the Elizabethan wars, the story of which he received orally from his father and his father's companions; it has the merits and defects incidental to a work so written — the vigour, the bitter partisanship, the inability to understand more than the personal issue, the inaccuracy of detail, and the confusion of dates. His other works, all in Latin, are 'Patriciana Decas,' a life of St. Patrick (1629); and a violent and abusive criticism of Archbishop Usher, under the title of Archicornigeromastix, sive Jacobi Usheri Heresiarchæ Confutatio.' He wrote also many lives of saints, which were not published, and in 1634 sent Bolland some contributions to his colossal undertaking. This is the last that is definitely known of him, though Webb has identified him with the
