"Lives" of the Saint have narrated on this subject, and given our
reasons for accepting the Armoric theory as the most reasonable
solution of the problem, it will be advisable to give a brief summary
of the arguments brought forward to prove that St. Patrick was an
Armorican Britain, born at Boulogne-sur-Mer.

Boulogne-sur-Mer, or ancient Bononia, was called by the same name,
"Bonaven," as the town in which St. Patrick implies that he was born.
Boulogne possessed a Roman encampment, and it was, therefore, Bonaven
Taberniae, mentioned in the "Confession."

Caligula's tower, on the north-eastern cliffs, in the town and within
the suburbs, was called "Turris Ordinis" by the Romans, but "Nemtor" by
the Gaulish Celts, as Hersart de la Villemarque states in his "Celtic
Legend."

It is certain that Niall of the Nine Hostages made use of the Port of
Boulogne when he invaded Armorica in the twenty-seventh year of his
reign, and that he died at that port after his assassination.

It is probable that Niall sailed to Boulogne when invading Armorica on
the first occasion, for he was carrying his arms into the same country,
of which Boulogne was the principal port, and the only one used by the
Romans when invading England.

The return of Niall from his first expedition into-Armorica with
captives, including St. Patrick, on board in the year 388, corresponds
precisely with the fifteenth year of St. Patrick, who was born in the
year 373. This fact is not only testified by Keating, but by Hersart de
la Villemarque in his "Celtic Legend," who narrates that Calphurnius,
