Seventh century.
Airmedach, Abbot of Craibhi-Lasri, occurs at the 1st day of January, in the
"Martyrology of Tallagh."' This saint is called Eirmbeadhach in the "Annals
of the Four Masters." Marianus O'Gorman inserts this
Hermetius in the Calendar at the 1st day of January. His birth may probably
be referred to the early part of the seventh century. The "Martyrology of
Donegal" mentions Ermedhach, Abbot of Craebh-Laisre,
as having been venerated at this day. In a table appended, the name of this
holy man is Latinized or Grecized, Hermes. The present saint died A.D. 681,
according to the "Annals of the Four Masters," or A.D. 682, according to
those of Ulster. Craebh-Laisre is said to be the name of a place near
Clonmacnoise. Some doubt has been entertained as to whether this saint had
been identical with a certain Hermetius, Bishop and Abbot of Clogher,
mentioned in the "Tripartite Life of St. Patrick." He is said to have
written Acts of the great Irish apostle. Craebh-Laisre means in English
"Laisre's Bush," or "Branch," viz., of the "Old Tree"
(
O'Hanlon).
