Book of Rights

The Leabhar-na gCeart (or the Book of Rights) was first written in the fifth century by St Benin, the successor of St Patrick, as archbishop of Armagh; but the work was afterwards enlarged, with many additions made by other writers, to the twelfth century. It gives an account of the Rights, Revenues, and Tributes of the Monarchs, Provincial Kings, and Princes; this work has been translated into English, and published by the Celtic Society. Copies of it are in the libraries of Trinity College, and of the Royal Irish Academy.
