We cannot close the illustrations of this ancient and venerable relic without adding an extract from a most interesting and authentic history of it contributed by our great Irish antiquarian, George Petrie, Esq., R.H.A., M.R.I.A, to the 18th vol. of the Transactions of the Royal Irish Academy, together with an engraving of it taken from a drawing made by the same accomplished artist. “I shall endeavor to arrange these evidences in consecutive order. “It is of importance to prove that this _cumdach_, or reliquary, has been from time immemorial popularly known by the name of _Domnach_, or, as it is pronounced, Donagh, a word derived from the Latin _Dominicus_. This fact is proved by a recent popular tale of very great power, by Mr. Carleton, called the 'Donagh,' in which the superstitious uses to which this reliquary has been long applied, are ably exhibited, and made subservient to the interests of the story. It is also particularly described under this name by the Rev. John Groyes in his account of the parish of Errigal-Keeroch in the third volume of Shaw Mason's Parochial Survey, page 163, though, as the writer states, it was not actually preserved in that parish. “2. The inscriptions on the external case leave no doubt that the Domnach belonged to the monastery of Clones, or see of Clogher. The John O'Karbri, the _Comharb_, or successor of St. Tighernach, recorded, in one of those inscriptions as the person at whose cost, or by whose permission, the outer ornamental case was made, was, according to the Annals of the Pour Masters, Abbot of Clones, and died in the year 1353. He is properly called in that inscription _Comorbanus_, or successor of Tighernach, who was the first Abbot and Bishop of the Church of Clones, to which place, after the death of St. Mac-Carthen, in the year 506, he removed the see of Clogher, having erected a new church, which he dedicated to the apostles Peter and Paul. St. Tighernach, according to all our ancient authorities, died in the year 548. “3. It appears from a fragment of an ancient life of St. Mac-Carthen, preserved by Colgan, that a remarkable reliquary was given by St Patrick to that saint when he placed him over the see of Clogher. “'Et addidit, [Patricius] Accipo, inquit, baculum itineris mei, quo ego membra mea sustento et scrinium in quo de sanctorum Apostolorum reliquiis, et de sanctae Mariae capillis, et sancta Grace Domini, et sepulchro ejus, et aliis reliquiis sanctis continentur. Quibus dictis dimisit cum osculo pacis paterna fultum benedictione.'--_Colgan, Vit. S. Macaerthenni_ (24 Mart.) Acta SS. p. 738. “From this passage we learn one great-cause of the sanctity in which this reliquary was held, and of the uses of the several recesses for reliques which it presents. It also explains the historical _rilievo_ on the top--the figure of St. Patrick presenting the Domnach to St. Mac-Carthen.
