A Compendium of Irish Biography/Vallancey, Charles
Vallancey, Charles, General, an antiquary, was born in England in 1721. He entered the army at an early age, was attached to the Royal Engineers, became a lieutenant-general in 1798, and a general in 1803. He came to Ireland before 1770 to assist in a military survey of the island, and made the country his adopted home. His attention was strongly drawn towards the history, philology, and antiquities of Ireland at a time when they were almost entirely ignored, and he published the following, among other works: Collectanea de Rebus Hibernicis, 6 vols., between 1770 and 1804; Essay on the Irish Language, 1772; Grammar of the Irish Language, 1773; Vindication of the Antient Kingdom of Ireland, 1786; Antient History of Ireland proved from the Sanscrit Books, 1797; Prospectus of a Dictionary of the Aire Coti or Antient Irish, 1802. He was a member of many learned societies, was created an honorary LL.D., and became a fellow of the Royal Society in 1784. During the Insurrection he furnished the Government with plans for the defence of Dublin. Queen's-bridge, Dublin, was built from his designs. He died 8th August 1812, aged 91. There are portraits of him in the Royal Irish Academy and in the board-room of the Royal Dublin Society. In the light of modern research his theories and conclusions—a fanciful compound of crude deductions from imperfect knowledge—are shown to be without value, and such as would not now receive a moment's attention. George Petrie says: "It is a difficult and rather unpleasant task to follow a writer so rambling in his reasonings and so obscure in his style; his hypotheses are of a visionary nature." The Quarterly Review declares that: "General Vallancey, though a man of learning, wrote more nonsense than any man of his time, and has unfortunately been the occasion of much more than he wrote. The Edinburgh Review says: "To expose the continual error of his theory will not cure his inveterate disease. It can only excite hopes of preventing infection by showing that he has reduced that kind of writing to absurdity, and raised a warning monument to all antiquaries and philologians that may succeed him."
