An ancient Irish harp attracts the attention of visitors from the repute attaching to it, of being the harp of Brian Boroimhe (pron. Boru, d. 1014). It is elegantly carved, and in form much resembles the harp of Queen Mary, an engraving of which is exhibited beside it. It had thirty strings. The following is the tradition respecting this harp, as quoted in the _Ulster Journal of Archæology_, vol. vii., p. 99, from a MS. by Ralph Ouseley, 1783.[134] “It had been taken to Rome, and remained there until Innocent XI. sent it as a token of good will to Charles II., who deposited it in the Tower. Soon afterwards, the Earl of Clanricarde, seeing it, assured the King that he knew an Irish nobleman (meaning O’Brien, Earl of Thomond) who would probably give a limb of his estate for this relic of his great ancestor; on which his Majesty made him a present of it. Lord Clanricarde brought the instrument to Ireland; but Lord Thomond, being abroad, never became possessed of it. Some years after, a Lady Henley purchased it by barter, in exchange for twenty rams and as many ewes of English breed, in order to give it to her son-in-law, Henry M‘Mahon, Esq., of Clunagh, County Clare; from whom it passed through other hands to an accomplished gentleman, the Right Hon. William Conyngham,” who presented it to Trinity College. Conyngham seems to have been given the harp by Chevalier O’Gorman, who gave a history of it (published in Vallancey’s _Collectanea_, vol. iv. 7) differing from that just quoted. According to O’Gorman’s story, Brian’s son Donogh, on being deposed, took the harp (with the crown and regalia) to Rome, and gave them to the Pope.[135] He adds the fiction that it was on the ground of possessing these regalia that Pope Adrian claimed the right to dispose of the lordship of Ireland. The story goes on to say that a later Pope gave the harp to Henry VIII., who presented it to the first Earl of Clanricarde.[136] The celebrated antiquary, Dr. George Petrie, considered that our harp dated from about A.D. 1400, and was a portable instrument used for ecclesiastical purposes. One strong objection to the earlier date he based on the fact that it bore a silver badge with the arms of O’Neill, armorial bearings not having been in use much earlier than the date he assigned. This badge disappeared for some time, and fortunately came into the possession of a distinguished antiquary, Mr. Robert Day, of Cork, affixed to a piece of armour found in some recent excavations in the Phœnix Park. As soon as Mr. Day learned the history of the badge, he promptly presented it to the Library. In its absence it was easy to observe that the carving was continuous, so that the badge must have been a later addition. Petrie’s first argument, therefore, fell to the ground. It is true, however, that the figures of two wolf-dogs are carved on the harp itself. His second objection was founded on the occurrence of the letters IHC, which may be traced
