Many people took an oath on the holy abbot’s relics and promised to obey “The Law of Adomnan”. Adomnan was twice desecrated by the Vikings: first in the ninth century and then again exactly 200 years later in the eleventh century. Adomnan can be found at Nether Leask in Aberdeenshire to this day.
In the same year the saint secured the exemption of women and children from compulsory military service (a purely pagan custom) and worked out the regulations that provided for the protection of children and clergy: Specifically, they exempted priests from military obligations.Adomnan a truce could be reached, the monks brought the saint’s relics to Ireland and visited forty churches that administratively belonged to Iona.And indeed, it became possible to reach a truce very soon.The composition of many beautiful poems in Gaelic is attributed by many scholars to Adomnan as well. It told of the spiritual insights and revelations received by Adomnan.This account enjoyed wide popularity in the Middle Ages. Adomnan reposed in peace in the Lord in the year 704 (according to another version, 705) as a very old man, venerated by all for his exemplary holy life and many years of labors for the good of the Holy Church.Historians suggest that for some time the saint headed the Skreen Monastery in the Irish county of Sligo; the area where this monastery stood once was known as “the Seals’ Hill”.
