forge, an accomplishment belonging to almost every Irish monk.

The writings of Adamnan, who spent most of his life outside his
native land, show that he was familiar with the best Latin authors,
and had a knowledge of Greek as well. His "Vita S. Columbae" ("Life
of St. Columcille") has made his name immortal as a Latin writer. His
book "De Locis Sanctis" ("On the Holy Places") contains information
he received from the pilgrim bishop Arculfus, who had been driven by
a tempest to take refuge with the monks of Iona. On account of the
importance of the writings of Adamnan and because of his influence in
secular and ecclesiastical affairs of importance, few will question
his right to a distinguished place among the saintly scholars of the
West.

Irish monks, abroad as well as at home, were pre-eminently students
and exponents of Holy Scripture. Sedulius wrote a commentary on the
Epistles of St. Paul; John Scotus Erigena composed a work, "De
Praedestinatione" ("Concerning Predestination"); Dungal was not only
an astronomer, but also an excellent theologian, as is clear from his
defence of Catholic teaching on the invocation of saints and the
veneration of their relics. His knowledge of Sacred Scripture and of
the Fathers is exceedingly remarkable.

St. Columbanus, besides other works, is said to have composed an
exposition of the Psalms, which is mentioned in the catalogue of St.
Gall's library, but which cannot now be identified with certainty.
The writings of this abbot are said to have brought about a more
frequent use of confession both in the world and in monasteries; and
his legislation regarding the Blessed Sacrament fostered eucharistic
devotion.
