We have fortunately still existing the main provisions of that constitution which was prepared under the auspices of Saint Patrick, and which, though not immediately, nor simultaneously, was in the end accepted by all Erin as its supreme law. It is contained in a volume called "the Book of Rights," and in its printed form (the Dublin bilingual edition of 1847), fills some 250 octavo pages. This book may be said to contain the original institutes of Erin under her Celtic Kings: "the Brehon laws," (which have likewise been published), bear the same relation to "the Book of Rights," as the Statutes at large of England, or the United States, bear to the English Constitution in the one case, or to the collective Federal and State Constitutions in the other. Let us endeavour to comprehend what this ancient Irish Constitution was like, and how the Kings received it, at first. There were, as we saw in the first chapter, beside the existing four Provinces, whose names are familiar to every one, a fifth principality of Meath. Each of the Provinces was subdivided into chieftainries, of which there were at least double or treble as many as there are now counties. The connection between the chief and his Prince, or the Prince and his monarch, was not of the nature of feudal obedience; for the fee-simple of the soil was never supposed to be vested in the sovereign, nor was the King considered to be the fountain of all honour. The Irish system blended the aristocratic and democratic elements more largely than the monarchical. Everything proceeded by election, but all the candidates should be of noble blood. The Chiefs, Princes, and Monarchs, so selected, were bound together by certain customs and tributes, originally invented by the genius of the Druids, and afterwards adopted and enforced by the authority of the Bishops. The tributes were paid in kind, and consisted of cattle, horses, foreign-born slaves, hounds, oxen, scarlet mantles, coats of mail, chess-boards and chess-men, drinking cups, and other portable articles of value. The quantity in every case due from a King to his subordinate, or from a subordinate to his King—for the gifts and grants were often reciprocal—is precisely stated in every instance. Besides these rights, this constitution defines the "prerogatives" of the five Kings on their journeys through each other's territory, their accession to power, or when present in the General Assemblies of the Kingdom. It contains, besides, a very numerous array of "prohibitions"—acts which neither the Ard-Righ nor any other Potentate may lawfully do. Most of these have reference to old local Pagan ceremonies in which the Kings once bore a leading part, but which were now strictly prohibited; others are of inter-Provincial significance, and others, again, are rules of personal conduct. Among the prohibitions of the monarch the first is, that the sun must never rise on him in his bed at Tara; among
