Among the moderns the majority leans to a contrary opinion; nevertheless, many authors of weight, distinguishing the public worship of the common people from the doctrine of the Druids, assert the monotheism of this sacerdotal caste. Samuel F. N. Morus particularly, who, with J. A. Ernesti, was esteemed the master of antiquarian scholarship in Europe during the last century, maintains, in his edition of the "Commentaries" of Caesar, that "human beings, as well as human affairs, fortunes, travels, and wars, were thought by the Celts to be governed and ruled by one supreme God, and that the system of apotheosis, common to nearly all ancient nations, was totally unknown in ancient Gaul, Britain, and the adjacent islands."

The ancient authorities concurring with these conclusions are so numerous and clear spoken that the great historian of Gaul, Amedee Thierry, thinks that such a pure and mystic religion, joined to such a sublime philosophy, could not have been the product of the soil. In his endeavor to investigate its origin, he supposes that it was brought to the west of Europe by the Eastern Cymris of the first invasion; that it was adopted by the higher classes of society, and that the old idolatrous worship remained in force among the lower orders.

The unity and omnipotence of the Godhead, metempsychosis, or the doctrine and the transmigration of soul —not into the bodies of animals, as it obtained and still obtains in the East, but into those of other human beings—the eternal duration of existing substances, material and spiritual, consequently the immortality of the human soul, were the chief dogmas of the Druids, according to the majority of antiquarians.

If this be true, then it can be said boldly that, with the exception of revealed religion in Judea, which was always far more explicit and pure, no system can be found in ancient times superior to that of the Druids, more especially if we add that, in addition to religious teaching, a whole system of physics was also developed in their large academies. "They dispute," says Caesar, "on the stars and their motions, on the size of the universe and of this earth, on the nature of physical things, as well as on the strength and power of the eternal God."

To bring our question home, what were the religious belief and worship of the Irish Celts while still pagans? Very few positive facts are known on the subject; but we have data enough to show what they were not; and in such cases negative proofs are amply sufficient.

It was for a long time the fashion with Irish historians to attribute to their ancestors the wildest forms of ancient idolatry. They appeared to consider it a point of national honor to make the worship of Erin an exact reflex of Eastern, Grecian, or Roman polytheism. They erected on the slightest foundations grand structures of superstitious and abominable rites. Fire- worship, Phoenician or African horrors, the rankest idol-worship, even human sacrifices of the most revolting nature, were, according to them, of almost daily occurrence in Ireland. But, with the advancement of antiquarian knowledge, all those phantoms have successively disappeared; and, the more the ancient customs, literature, and history of the island are studied, the more it becomes clear that the pretended proofs adduced in support of those vagaries are really without foundation.

In the first place, there is not the slightest reason to believe that the human sacrifices customary in Gaul were ever practised in Ireland. No really ancient book makes any mention of them. They were certainly not in vogue at the time of St. Patrick, as he could not have failed to give expression to his horror at them in some shape or form, which expression would have been recorded in one, at least, of the many lives of the saint, written shortly after his death, and abounding in details of every kind. If not, then, during his long apostleship, we may safely conclude that they never took place before, as there was no reason for their discontinuance prior to the propagation of Christianity.

There was a time when all the large cromlechs which abound in the island were believed to be sacrificial stones; and it is highly probable that the opinion so prevalent during the last century with respect to the reality of those cruel rites had its origin in the existence of those rude monuments. After many investigations and excavations around and under cromlechs of all sizes, it is now admitted by all well-informed antiquarians that they had no connection with sacrifices of any kind. They were merely monuments raised over the buried bodies of chieftains or heroes. Many sepulchres of that description have been opened, either under cromlechs or under large mounds; great quantities of ornaments of gold, silver, or precious stones, utensils of various materials, beautiful works of great artistic merit, have been discovered there, and now go to fill the museums of the nation or private cabinets. Nothing connected with religious rites of any description has met the eyes of the learned seekers after truth. Thus it has been ascertained that the old race had reached a high degree of material civilization; but no clew to its religion has been furnished.

As to fire-worship, which not long ago was admitted by all as certainly forming a part of the Celtic religion in Ireland, so little of that opinion remains to-day that it is scarcely deserving of mention. There now remains no doubt that the round towers, formerly so numerous in Ireland, had nothing whatever to do with fire-worship. For a long time they were believed to have been constructed for no other object, and consequently long prior to the coming of St. Patrick. But Dr. Petrie and other antiquarians have all but demonstrated that the round towers never had any connection with superstition or idolatry at all; that they were of Christian origin, always built near some Christian church, and of the same materials, and had for their object to call the faithful to prayer, like the campanile of Italy, to be a place of refuge for the clergy in time of war, and to give to distant villages intimation of any hostile invasion.

The fact in the life of St. Patrick, when he appeared before the court of King Laeghaire, upon which so much reliance is placed as a proof of the existence of fire-worship, is now of proportionate weakness. It seems, to judge by the most reliable and ancient manuscripts, that, after all, the kindling of the king's fire was scarcely a religious act.
