I come now to the most celebrated of all the pre-Celtic folks that inhabited Ireland, the Fir Bolg. In including these among the industrial castes of ancient Ireland, I claim the support of the oldest written traditions, which clearly tell that the Fir Bolg, or "Men of Bags," obtained that name from an industrial connection with leathern bags. The story of the origin of the name, as found in the Book of Invasions, Keating's History, etc., is no doubt well-known. They migrated, we are told, from Ireland to Greece (Greece in ancient Irish writings means the Eastern Empire). There, being outlanders, according to the ideas of our forefathers, they did not obtain the local franchises and became a serf people. Their occupation was to carry sand and earth in leathern bags and spread a soil over rocky places, as is still done in parts of Ireland, to make fertile land. From this occupation, they were named Fir Bolg. They afterwards used the hides in which they worked to construct ships in the ancient fashion, and in these ships they escaped back to Ireland and liberty.
Quite a different version of the story is found in the Book of Lecan, a book which contains a great miscellany, awaiting most desirable publication, of excerpts from older writings, especially excerpts of material which does not accord with what one may call the received teachings of later times on matters of Irish legend and tradition. This particular passage contains what is doubtless the oldest extant account of the Fir Bolg. Its language, in my opinion, is of not later date than the eighth century. Like the accepted story, it says that they were a branch of the race of Nemed, but unlike the accepted story, it does not say that they left Ireland in a body and came back to it in a body after many years. On the contrary, it tells us that they continued to inhabit Ireland all the time, but carried on a particular trade with the eastern world. The manner of their trade was this. They put Irish earth into leathern bags and exported it to the east, where they sold it to the Greeks to be spread on the ground around their cities as a protection against venomous reptiles. From this trade they got the name of Bagmen.
Dubhaltach Mac Fir Bhisigh, in the unpublished introduction to his Book of Genealogies, tells us that Fir Bolg was the specific name of a particular section of the pre-Gaelic population, but became extended in common usage so as to be applied to the whole of that population. Of this statement we have abundant corroboration, with details enabling us to locate the abode of various sections of the Bag-folk properly so called. One section, called Bolgraighe, was the principal Rent-paying community of the ancient Tir Conaill, a territory of much smaller extent than the Tir Conaill of later times. Another section inhabited the district of Sliabh Badbgna (Slieve Baune) in the east of County Roscommon, where, I have been told, popular tradition still recognises their descendants. Another section dwelt in the district of Cong in the south of County Mayo, another in Sliabh Eachtgha (Aughty) in the south of County Galway.
The manufacture of bags from hide or leather was no doubt not a highly esteemed occupation, and it was probably out of contempt that the name Fir Bolg was extended to the whole conquered population by the Celtic ascendancy. The subject communities produced not only skilled artisans but men of great piety and learning in early Christian times. Saint Mo-Chuarog, for example, who is called Sapiens, "the Learned," and who introduced a reform into the Irish chronography of his time, was a member of the Rivet-folk, the Seamonraighe of the Déisi. But the general attitude of the Gaels towards the older population was undoubtedly disdainful. The passage quoted by Dubhaltach from "an ancient book" is familiar to many in O'Curry's translation:
"Every one who is black-haired, who is a tattler, guileful, tale-telling, noisy, contemptible; every wretched, mean, strolling, unsteady, harsh and inhospitable person; every slave, every mean thief, every churl, every one who loves not to listen to music and entertainment, the disturbers of every council and every assembly, and the promoters of discord among people—these are the descendants of the Firbolgs, of the Galians, of the Liogairne, and of the Fir Domhnann in Eirinn. But the descendants of the Fir Bolg are the most numerous of all these."
This is fine old ascendancy talk, the sort of language that has served in many ages to justify the oppression of liberty; and there is plenty of evidence that the older population was in some instances subjected to very harsh treatment—in some instances, not in all, nor were the ancient communities always spoken of in such terms of contempt.
Among them, besides industrial groups or castes, there were also others which appear to have followed the profession of arms. Cú Chulainn, according to one tradition preserved by Dubhaltach, belonged to a non-Gaelic tribe called Tuath Tabhairn, and it will be remembered that he is once described as "a small dark man." "Thou little elf!" his charioteer used to call him, to provoke him to do his utmost in the fight. His rival, Fear Diadh, was a noble of the Fir Domhnann from Connacht, and the Fir Domhnann still existed as a subject community in the times to which the tract on the Rent-paying Folks has relation. They are located in a stretch of country comprising the greater part of the counties of Mayo and Sligo. In the eastern Midlands, from the Shannon to the Irish Sea, the same tract places another of these ancient tribes named the Luaighni—a name still preserved in that of the barony of Lune in Meath. These are represented as forming the chief fighting force of the kings of North Leinster in the heroic period. When Conchobhar sets out to exact reparation for the Táin and the invasion of Ulster, he is met by the forces of the Luaighni at Rosnaree on the Boyne, his heroes one after another are worsted in the fight, his army almost routed, and it is only when their king has fallen in single combat that the Luaighni abandon the field. In the curious story of the revolution brought about by the revolt of the Rent-paying tribes against the oppressive rule of the Gaelic nobility, it is the chief of the Luaighni, Cairbre of the Cat's Head, who becomes king of Ireland for twenty years.
Still more remarkable is the tribute of the ancient saga to the valour and discipline of the Galians. In the ninth century the Galians are still described by the poet Mael Muru as one of the outstanding sections of the population who are not Gaels. The tract on the Rent-paying Folks divides them into three tuatha and gives the location of each. They inhabited the northern parts of old Leinster, in the present counties of Wicklow, Kildare, and King's County. The story of the Táin tells how the Galians excelled all the other troops that joined Medb on her march from Cruachain for the invasion of Ulster. "This enterprise," said the warlike queen, "will be a barren one for all of us, except for one force alone, the Galians of Leinster." "Why blamest thou these men?" said her consort. "Blame them we do not," replied Medb. "What good service then have they done that they are praised above the rest?" said Ailill. "There is reason to praise them," said Medb. "They are splendid soldiers. When the rest are beginning to make their pens and pitch their camps, the Galians have already finished setting up their booths and huts. When the rest are still building booths and huts, the Galians have finished preparing their food and drink. While the others are getting ready their food and drink, the Galians have done eating and feasting, and their harps are playing for them. When all the others have finished eating and feasting, by that time the Galians are asleep. And even as their servants and thralls are distinguished above the servants and thralls of the Men of Erin, so shall their heroes and champions be distinguished above the heroes and champions of the men of Erin on this hosting. It is folly then for the rest to go, for the Galians will enjoy the victory." And in fear and jealousy the queen declared that nothing would please her but to fall upon the Galians and destroy them. Her husband expostulated. "Shame on thy speech!" he said, "a woman's counsel, for no better reason than because they pitch their tents and make their pens so promptly and unwearily." And Fergus interposing swore that he and his Ulstermen would stand by the Galians to the death. The Galians, he said, are but one division in eighteen of our army. Even so, we shall take care that they shall be no danger to us. And he took and divided the forces of the Galians among the rest so that not five of them were in one place together.
Of this Galian stock came Fionn and Oisin and Oscar and all their kindred, according to some accounts. They were of the sept Ui Tairsigh, one of the three folks who, says Mael Muru, are not of the Gaedhil. This sept dwelt at Drumcree in the barony of Delvin in Westmeath. Their name and existence as a sept is probably not so ancient as the time of Fionn, but we may suppose that in their own time they claimed descent from the family of Fionn, from Clann Bhaoisgne.
