We have already compared the shape of Erin to a shield, in which the four Provinces represented the four quarters. Some shields have also _bosses_ or centre-pieces, and the federal province of MEATH was the _boss_ of the old Irish shield. The ancient Meath included both the present counties of that name, stretching south to the Liffey, and north to Armagh. It was the mensal demesne, or "board of the king's table:" it was exempt from all taxes, except those of the Ard-Righ, and its relations to the other Provinces may be vaguely compared to those of the District of Columbia to the several States of the North American Union. ULSTER might then be defined by a line drawn from Sligo Harbour to the mouth of the Boyne, the line being notched here and there by the royal demesne of Meath; LEINSTER stretched south from Dublin triangle-wise to Waterford Harbour, but its inland line, towards the west, was never very well defined, and this led to constant border wars with Munster; the remainder of the south to the mouth of the Shannon composed MUNSTER; the present county of Clare and all west of the Shannon north to Sligo, and part of Cavan, going with CONNAUGHT. The chief seats of power, in those several divisions, were TARA, for federal purposes; EMANIA, near Armagh, for Ulster; LEIGHLIN, for Leinster; CASHEL, for Munster; and CRUCHAIN, (now Rathcrogan, in Roscommon,) for Connaught. How the common people lived within these external divisions of power it is not so easy to describe. All histories tell us a great deal of kings, and battles, and conspiracies, but very little of the daily domestic life of the people. In this respect the history of Erin is much the same as the rest; but some leading facts we do know. Their religion, in Pagan times, was what the moderns call _Druidism_, but what they called it themselves we now know not. It was probably the same religion anciently professed by Tyre and Sidon, by Carthage and her colonies in Spain; the same religion which the Romans have described as existing in great part of Gaul, and by their accounts, we learn the awful fact, that it sanctioned, nay, demanded, human sacrifices. From the few traces of its doctrines which Christian zeal has permitted to survive in the old Irish language, we see that _Belus_ or "Crom," the god of fire, typified by the sun, was its chief divinity—that two great festivals were held in his honour on days answering to the first of May and last of October. There were also particular gods of poets, champions, artificers and mariners, just as among the Romans and Greeks. Sacred groves were dedicated to these gods; Priests and Priestesses devoted their lives to their service; the arms of the champion, and the person of the king were charmed by them; neither peace nor war was made without their sanction; their own persons and their pupils were held sacred; the high place at the king's right hand and the best fruits of the earth and the waters were theirs.
