THE Fifth "Life," written by Probus, an Irish monk, who died at Meyence in the year 859, is regarded as the best of the old Latin "Lives" of St. Patrick; it is considered to be an amended edition of the "Book of Armagh," written by Muirchu Macc-Mactheni, so truly that the blank left by the missing folio in that famous book can be filled in by copying the "History of Probus." (Canon O'Hanlon's "Lives of the Irish Saints," March 17th.) The "Life of St. Patrick," by Probus, commences as follows:-- "Cap. I.--St. Patrick, who was also called Suchet, was a Briton by nationality. . . . He was born in Britain [in Britanniis], being the son of Calphurnius, a deacon, who was the son of Potitus, a priest, and his mother was named Conchessa, in a district within the region of Bannaue Tiburniae, not far from the Western Sea, which district, as we have discovered beyond doubt, was situated in the province of Nentria, where the giants are said to have formerly dwelt." "XII.--When he was in his own country with his father Calphurnius and his mother Conchessa, in their own seaside city [city Arimuric] there was a great outbreak of hostilities in these parts. The sons of King Rithmit, coming from Britain, laid Arimuric and the surrounding country waste. They massacred Calphurnius and his wife Conchessa; but their children, Patrick and his brother Ruchti, together with their sister Mila, they took captives to Ireland. They sold Patrick to Prince Milcho, but his brother Ruchti and his sister Mila to another Prince." Colgan, in his annotations, substitutes Neutria for Nentria (4), and Armorica for Arimuric, Caesar testifies that all the towus on the sea coast of Armorica were called Armoricse (Britannia, vol i. p. 13). "In his own city Armuric" has therefore been rendered "in his own seaside city." When Probus wrote his history there was no province in existence called either Nentria or Neutria; but there was a province called Neustria, which embraced Armorica or the northern sea coast of Gaul, where St. Patrick was residing in his own native country (in patria) with his parents, when he was made captive. It follows, likewise, that St. Patrick's native town, "Bannaue Tiburnise," according to Probus, was the seaside city in Armorica referred to. The Bannaue Tiburniae of Probus and the Bonaven Taberniae of St. Patrick are evidently one and the same as Bononia, where the Romans were encamped, which, as it has already been proved, was called Bonauen Armorik by the Gaulish Celts. If any other proof were needed, the description of the province given by Probus as the country formerly inhabited by giants can leave no doubt on the subject.
