The enactments of this synod were afterwards known in Latin as “Lex Adamnani,” and in Gaelic “Cain Adhamhnain.” In addition to a certain privilege conceded to him and to his successors of levying contributions for sacred purposes, Dr. Reeves thinks it was on this occasion that the questions of Easter and the tonsure were publicly discussed, and Adamnan’s views and usage adopted in Ireland. Afterwards he seems to have been some years in that country promoting his reforms. He certainly was there in 701; and Bede mentions that he crossed from Erin to Hy the summer of the year that he died, and indicates that he had been there a considerable time previously. His death occurred on September 23rd, 704. It is thus touchingly commemorated by the great historian. “For it came to pass that before the next year came round he departed this life; the Divine goodness so ordering it that, as he was a man most earnest for peace and unity, he should be taken away to everlasting life before the return of the season of Easter he should be obliged to differ still more seriously from those who were unwilling to follow him in the way of truth.” He had apparently celebrated his last Easter in Ireland, and died at the mature age of seventy-seven. His fame rests on his writings, chiefly the _Life of St. Columba_, and his book on the “Holy Places”—_De Locis Sanctis_. Adamnan himself saw not these Holy Land localities, but a French bishop on his return from the east was driven by a storm to spend the winter with Adamnan, who took down on waxen tablets his interesting accounts of the chief places visited, and afterwards wrote out, _brevi textu_, on parchment. It is better written and more fluent even than the biography, and when found many years after, it was published as “the earliest account coming from modern Christian Europe of the condition of Eastern lands and the cradle of Christianity.” Adamnan presented the book to King Aldfrid of Northumbria. There are extant MSS. of it as old as the eighth, ninth, and tenth centuries still on the Continent—at Rome, Corbey, Saltzburg, and other places. Besides these chief Latin works he is credited with a _Life of St. Patrick_; poems, quoted by Tighernach, the “Four Masters,” and the Book of Lecain; a _History of Ireland_ to his own times, and _An Epitome of Irish Laws in Metre_. These two latter are only mentioned by Ward[16] (on what authority is not known), and may be probably only compilations of more modern times.
