Moreover, the Celtic Rule of Columbanus was carried into Picardy by
St. Valery, St. Omer, St. Bertin, St. Mummolin, and St. Valdelenus;
but the Irish Caidoc and Fricor had already preceded them, their work
resulting in the foundation of the Abbey of St. Riquier.

ITALY: Something yet remains to be said of the monks of Ireland in
Italy. Anterior to St. Columbanus's migration, his fellow countryman,
St. Frigidian (or Fridian), had taken up his abode in Italy at Monte
Pisana, not far from the city of Lucca, where he became famed for
sanctity and wisdom. On the death of the bishop of Lucca, Frigidian
was compelled to occupy the vacant see. St. Gregory the Great wrote
of him that "he was a man of rare virtue". His teachings and holy
life not only influenced the lives of his own flock, but brought to
the faith many heretics and pagans. In Lucca this Celtic apostle is
still honored under the name of St. Frediano.

St. Pellegrinus is another Irish saint who sought solitude at
Garfanana in the Apennines; and Cathaldus, a Waterford saint, in 680,
became Bishop of Taranto, which he governed for many years with zeal
and great wisdom. His co-worker was Donatus, his brother, who founded
the church at Lecce in the Kingdom of Naples.

Of the two learned Irishmen, Clemens and Albinus, who resided in
France in the eighth century, Albinus was sent into Italy, where at
Pavia he was placed at the head of the school attached to St.
Augustine's monastery. Dungal, his compatriot, was a famous teacher
in the same city. Lothair thus ordained concerning him: "We desire
that at Pavia, and under the superintendence of Dungal, all students
should assemble from Milan, Brescia, Lodi, Bergamo, Novara, Vercelli,
Tortona, Acqui, Genoa, Asti, Como."
