Know then, most Holy Father, that since the time when our early ancestors, the three sons of Milesius or Micelius of Spain, by God’s will came into Ireland (then destitute of all inhabitants) with a fleet of thirty ships from Cantabria, a city of Spain standing on the bank of the river Ebro or Hiberus (from which we take the name we bear), 3,500 years and more have passed, and of those descended from these men, 136 kings without admixture of alien blood assumed the monarchical rule over all Ireland down to king Legarius, from whom I, Donald, have derived my descent in a straight line. It was in [those] days that our chief apostle and patron St. Patrick, sent us at the inspiration of the Holy Ghost by your predecessor Celestine in the year 432 taught the truths of the Catholic Faith with the fullest success to our fathers.
And after the Faith had been preached and received, 61 kings of the same blood, without intervention of alien blood, kings admirably in the faith of Christ and filled with works of charity, kings that in temporal things acknowledged no superior, ruled here uninterruptedly in humble obedience to the Church of Rome until the year 1170.
And it was they, not the English nor others of any nation who eminently endowed the Irish Church with lands, ample liberties and many possessions, although at the present time she is, for the most part, sadly despoiled of those lands and liberties by the English.
