now left but some few pieces of hia own writing, and a few old rammish books of history, printed." O'Flaherty was of a commanding presence, and was proud of his blood and ancestry. He was a strange mixture of simplicity and wisdom ; and amongst his neighbours had the reputation of being able to work miracles and exor- cise evil spirits. He died in 1718, aged about 89, leaving an only son Michael, to whom, in 1 736, a portion of the family estates was restored. "^^ ^*^

O'Flinu, Eochaidh, an eminent Irish writer, who died in 984. O'Curry gives a particular account of his writings, several of which have been preserved in the Books of Leinster, Ballymote, and Lecain, and O'Clery's Book of Invasions. ^'

O'Glacan, ITeil, a distinguished phy- sician who flourished in the early part of the 1 7th century, was born in the Coimty of Donegal. He studied medicine, and ad- vanced himself to the position of Professor of Medicine at Toulouse, and Physicijm and Privy-Councillor to the King of France. He travelled in Spain to make observations upon the plague, and ultimately removed to Bologna, where he was much esteemed, and where he probably died. He wrote Trac- tatus dePeste (Toulouse, 1629), and Cursus Medicus (Bologna, 1655). 339

O'Gorman, Marian, or Maelmnire, Abbot of Knock, near Louth, composed in 1 171 a calendar generally known as the Calendar of Marianus. Colgan says it is in elegant Irish verse, and much esteemed for its beauty of style and faithfulness of detail. The only old copy of this manu- script is preserved in the Burgundian Library at Brussels. Dr. Todd and Dr. Beeves considered it sufficiently valuable to have transcripts made for their private use. ^33 339

O'Halloran, Silvester, surgeon and historian, was born in Limerick, 31st De- cember 1 728. He studied medicine in the schools of London, Paris, and Leyden, and devoted himself to practice in his native city. Before he was twenty-one he pub- lished a Treatise on Cataract, the first of several medical essays from his pen. Archteology divided his attention with medicine ; he was an Irish scholar, and one of the earliest members of the Eoyal Irish Academy. A treatise on the pre- servation of ancient annals appeared in 1770 ; An Introduction to the Study of the Antiquities of Ireland, in 1772 ; his General History of Ireland, in 2 vols. 4to. London, 1774; besides minor papers read before the Academy and else- where. His ^'History is now but little referred to, as the most valuable and ac-

It is distinguished throughout by great national enthusiasm and considerable erudition, but its topo- graphical descriptions, though on the whole tolerably correct, have been in many in- stances revised and altered by modern in- vestigators. . . It was an astonishing performance at the date of its publica- tion." "s He is spoken of by a contempo- rary as " the tall, thin doctor, in his quaint French dress, with his gold-headed cane, beautiful Parisian wig, and cocked hat ;.

His portrait is prefixed to a notice in the Dublin Journal of Medical Science, vol vi. [One of his sons, Joseph, entered the army, served fifteen years in India, and rose to be Lieutenant-General Sir Joseph O'Halloran : he died in London about 1843, aged 80.] "s 196 "s

O'HaiUou, Redmond, a dispossessed proprietor of Ulster, under the Cromwel- lian settlement, and leader of a band of outlaws. [His father or grandfather, here- ditary Royal Standard-bearer north of the Boyne, was killed in 1 600 at the pass of Carlingford, fighting on the English side. James I. bestowed upon his family seven townlands, of which they were dispossessed in 1653, under the Cromwellian settlement, receiving some pittance of land in Con- naught. J Redmond headed a band of " tories," and kept the counties of Tyrone and Armagh in terror, the farmers paying him regular contributions to be protected from other outlaws. He thought more than once of retiring to France, where he was known to fame as Count O'Hanlon ; but the expectation of a French invasion, and the hope of retrieving his ancestral lands kept him at home. He was at length betray- ed by his foster-brother in the hills near Eight-mile-Bridge, in the County of Down, 25th April 1 68 1, and his head was placed over the jail of Downpatrick. Many other dispossessed proprietors followed O'Hanlon's example. Colonel Poer in Munster, Colonel Coughlan in Leinster, and Colonel Dudley Costello in Connaught, headed bands of tories that gave infinite trouble to the Government. '3

O'Hara, Sir Charles, Baron Ti- rawley, an officer distinguished in the War of the Spanish Succession, was born in the County of Mayo, in 1640. He was raised to the peerage in 1706.
