"The _Senchus Mor_ has been selected by the commissioners for early publication as being one of the oldest and one of the most important portions of the ancient laws of Ireland which have been preserved. It exhibits the remarkable modification which these laws of pagan origin underwent, in the fifth century, on the conversion of the Irish to Christianity. "This modification was ascribed so entirely to the influence of St. Patrick that the _Senchus Mor_ is described as having been called in after times 'Cain Patraic,' or Patrick's law. "The _Senchus Mor_ was so much revered, that the Irish judges, called Brehons, were not authorized to abrogate anything contained in it. "The original text, of high antiquity, has been made the subject of glosses and commentaries of more recent date; and the _Senchus Mor_ would appear to have maintained its authority among the native Irish until the beginning of the seventeenth century, or for a period of 1,200 years. "The English law, introduced by King Henry the Second in the twelfth century, for many years scarcely prevailed beyond the narrow limits of the English pale (comprising the present counties of Louth, Meath, Westmeath, Kildare, Dublin, and Wicklow). Throughout the rest of Ireland the Brehons still administered their ancient laws amongst the native Irish, who were practically excluded from the privileges of the English law. The Anglo-Irish, too, adopted the Irish laws to such an extent that efforts were made to prevent their doing so by enactments first passed at the parliament of Kilkenny in the fortieth year of King Edward III. (1367), and subsequently renewed by Stat. Henry VII., c. 8, in 1495. So late as the twenty-fourth and twenty-fifth years of the reign of King Henry VIII. (1534) George Cromer, archbishop of Armagh and primate of Ireland, obtained a formal pardon for having used the Brehon laws. In the reign of Queen Mary, 1554, the Earl of Kildare obtained an eric of 340 cows for the death of his foster-brother, Robert Nugent, under the Brehon law. "The authority of the Brehon laws continued until the power of the Irish chieftains was finally broken in the reign of Queen Elizabeth, and all the Irish were received into the king's immediate protection by the proclamation of James I. This proclamation, followed as it was by the complete division of Ireland into counties, and the administration of the English laws throughout the entire country, terminated at once the necessity for, and the authority of, the ancient Irish laws. "The wars of Cromwell, the policy pursued by King Charles II. at the restoration, and the results of the revolution of 1688, prevented any revival of the Irish laws; and before the end of the seventeenth century the whole race of judges (Brehons) and professors (Ollamhs) of the Irish laws appears to have become extinct." {131}
