"It was in this church that the last princes of Tyrone and Tyrconnel were interred. In the second row of tombs with which the pavement of the church is lined, the Irish traveller will find without difficulty the epitaph of Hugh baron of Dungannon, who died in September, 1609, and of the two O'Donnells, who died in the autumn of 1608.[20] It is known that Hugh O'Neil, earl of Tyrone, was also interred here; but hitherto his tomb has been sought for in vain. The archives of the adjoining monastery, however, have at length come to our aid. The last great Irish chieftain expired in the Palazzo Salviati, on the 20th of July, 1616, and the register of San Pietro-in-Montorio marks the 24th of July, 1616, as the day on which his remains were, with princely pomp, laid within its vaults. This same register further tells us that his epitaph, now wholly obliterated, held _the first place in the third row_ of tombs which mark the pavement of the church, and that it consisted of the simple record: D. O. M. HIC QUIESCUNT OSSA HUGONIS PRINCIPIS O'NEILL. "It was alongside the tomb of Hugh O'Neil that Eugene Matthews, archbishop of Dublin, reposed in death. His epitaph, says the register of the church, holds _the second place in the third row of tombs_. The slab which corresponds with this indication now only retains some faint traces of letters here and there, it being impossible to decipher even one word of its original inscription. Here again the church register comes to our aid; it tells us that the following was the inscription on Dr. Matthews' tomb: D. O. M. EUGENIO MATTHEI, ARCHIEPISCOPO DUBLINENSI, DOCTRINÆ CLARITATE NATALIUM SPLENDORE, FIDE IN DEUM PIETATE IN PATRIAM SINGULARI QUI POSTQUAM SOLLICITI PASTORIS, DIUTURNO AC DIFFICILI TEMPORE IN HIBERNIA, NUMEROS OMNES ADIMPLESSET, SUB GREGORIO XV., ROMAM VENIT, UBI AB OPTIMO PONTIFICE BENIGNE HABITUS, DUM PATRIÆ SUÆ NEGOTIA PROMOVERET, EXTREMUM DIEM CLAUSIT KAL. SEPT. 1623.
