by the folk before the coming of S. Patrick. Even the saint and several bishops were called by the fair pagan daughters of King Loegaire, fir síde, "men of the síd," that is, gods.207 The síd were named after the names of the Tuatha Dé Danann who reigned in them, but the tradition being localised in different places, several mounds were sometimes connected with one god. The síd were marvellous underground palaces, full of strange things, and thither favoured mortals might go for a time or for ever. In this they correspond exactly to the oversea Elysium, the divine land.
But why were the Tuatha Dé Danann associated with the mounds? If fairies or an analogous race of beings were already in pagan times connected with hills or mounds, gods now regarded as fairies would be connected with them. Dr. Joyce and O'Curry think that an older race of aboriginal gods or síd-folk preceded the Tuatha Déa in the mounds.208 These may have been the Fomorians, the "champions of the síd," while in Mesca Ulad the Tuatha Déa go to the underground dwellings and speak with the síde already there. We do not know that the fairy creed as such existed in pagan times, but if the síde and the Tuatha Dé Danann were once distinct, they were gradually assimilated. Thus the Dagda is called "king of the síde"; Aed Abrat and his daughters, Fand and Liban, and Labraid, Liban's husband, are called síde, and Manannan is Fand's consort.209 Labraid's island, like the síd of Mider and the land to which women of the síde invite Connla, differs but little from the usual divine Elysium, while Mider, one of the síde, is associated with the Tuatha Dé Danann.210 The síde are once said to be female, and are frequently supernatural women who run away or marry mortals.211 Thus they may be a reminiscence of old Earth goddesses. But they are not exclusively female, since there are kings of the síde, and as the name Fir síde, "men of the síde," shows, while S. Patrick and his friends were taken for síd-folk.
The formation of the legend was also aided by the old cult of the gods on heights, some of them sepulchral mounds, and now occasionally sites of Christian churches.212 The Irish god Cenn Cruaich and his Welsh equivalent Penn Cruc, whose name survives in Pennocrucium, have names meaning "chief or head of the mound."213 Other mounds or hills had also a sacred character. Hence gods worshipped at mounds, dwelling or revealing themselves there, still lingered in the haunted spots; they became fairies, or were associated with the dead buried in the mounds, as fairies also have been, or were themselves thought to have died and been buried there. The haunting of the mounds by the old gods is seen in a prayer of S. Columba's, who begs God to dispel "this host (i.e. the old gods) around the cairns that reigneth."214 An early MS also tells how the Milesians allotted the underground part of Erin to the Tuatha Déa who now retired within the hills; in other words, they were gods of the hills worshipped by the Milesians on hills.215 But, as we shall see, the gods dwelt elsewhere than in hills.216
Tumuli may already in pagan times have been pointed out as tombs of gods who died in myth or ritual, like the tombs of Zeus in Crete and of Osiris in Egypt. Again, fairies, in some aspects, are ghosts of the dead, and haunt tumuli; hence, when gods became fairies they would do the same. And once they were thought of as dead kings, any notable tumuli would be pointed out as theirs, since it is a law in folk-belief to associate tumuli or other structures not with the dead or with their builders, but with supernatural or mythical or even historical personages. If síde ever meant "ghosts," it would be easy to call the dead gods by this name, and to connect them with the places of the dead.217
Many strands went to the weaving of the later conception of the gods, but there still hung around them an air of mystery, and the belief that they were a race of men was never consistent with itself.
Danu gave her name to the whole group of gods, and is called their mother, like the Egyptian Neith or the Semitic Ishtar.218 In the annalists she is daughter of Dagda, and has three sons. She may be akin to the goddess Anu, whom Cormac describes as "mater deorum hibernensium. It was well she nursed the gods." From her name he derives ana, "plenty," and two hills in Kerry are called "the Paps of Anu."219 Thus as a goddess of plenty Danu or Anu may have been an early Earth-mother, and what may be a dim memory of Anu in Leicestershire confirms this view. A cave on the Dane Hills is called "Black Annis' Bower," and she is said to have been a savage woman who devoured human victims.220 Earth-goddesses usually have human victims, and Anu would be no exception. In the cult of Earth divinities Earth and under-Earth are practically identical, while Earth-goddesses like Demeter and Persephone were associated with the underworld, the dead being Demeter's folk. The fruits of the earth with their roots below the surface are then gifts of the earth- or under-earth goddess. This may have been the case with Danu, for in Celtic belief the gifts of civilisation came from the underworld or from the gods. Professor Rh^ys finds the name Anu in the dat. Anoniredi, "chariot of Anu," in an inscription from Vaucluse, and the identification is perhaps established by the fact that goddesses of fertility were drawn through the fields in a vehicle.221 Cormac also mentions Buanann as mother and nurse of heroes, perhaps a goddess worshipped by heroes.222
Danu is also identified with Brigit, goddess of knowledge (dán), perhaps through a folk-etymology. She was worshipped by poets, and had two sisters of the same name connected with leechcraft and smithwork.223 They are duplicates or local forms of Brigit, a goddess of culture and of poetry, so much loved by the Celts. She is thus the equivalent of the Gaulish goddess equated with Minerva by Cæsar, and found on inscriptions as Minerva Belisama and Brigindo. She is the Dea Brigantia of British inscriptions.224 One of the seats of her worship was the land of the Brigantes, of whom she was the eponymous goddess, and her name (cf. Ir. brig, "power" or "craft"; Welsh bri, "honour," "renown") suggests her high functions. But her popularity is seen in the continuation of her personality and cult in those of S. Brigit, at whose shrine in Kildare a sacred fire, which must not be breathed on, or approached by a male, was watched daily by nineteen nuns in turn, and on the twentieth day by the saint herself.225 Similar sacred fires were kept up in other monasteries,226 and they point to the old cult of a goddess of fire, the nuns being successors of a virgin priesthood like the vestals, priestesses of Vesta. As has been seen, the goddesses Belisama and Sul, probably goddesses of fire, resembled Brigit in this.227 But Brigit, like Vesta, was at once a goddess of fire and of fertility, as her connection with Candlemas and certain ritual survivals also suggest. In the Hebrides on S. Bride's day (Candlemas-eve) women dressed a sheaf of oats in female clothes and set it with a club in a basket called "Briid's bed." Then they called, "Briid is come, Briid is welcome." Or a bed was made of corn and hay with candles burning beside it, and Bride was invited to come as her bed was ready. If the mark of the club was seen in the ashes, this was an omen of a good harvest and a prosperous year.228 It is also noteworthy that if cattle cropped the grass near S. Brigit's shrine, next day it was as luxuriant as ever.
Brigit, or goddesses with similar functions, was regarded by the Celts as an early teacher of civilisation, inspirer of the artistic, poetic, and mechanical faculties, as well as a goddess of fire and fertility. As such she far excelled her sons, gods of knowledge. She must have originated in the period when the Celts worshipped goddesses rather than gods, and when knowledge—leechcraft, agriculture, inspiration—were women's rather than men's. She had a female priesthood, and men were perhaps excluded from her cult, as the tabued shrine at Kildare suggests. Perhaps her fire was fed from sacred oak wood, for many shrines of S. Brigit were built under oaks, doubtless displacing pagan shrines of the goddess.229 As a goddess, Brigit is more prominent than Danu, also a goddess of fertility, even though Danu is mother of the gods.
Other goddesses remembered in tradition are Cleena and Vera, celebrated in fairy and witch lore, the former perhaps akin to a river-goddess Clota, the Clutoida (a fountain-nymph) of the continental Celts; the latter, under her alternative name Dirra, perhaps a form of a goddess of Gaul, Dirona.230 Aine, one of the great fairy-queens of Ireland, has her seat at Knockainy in Limerick, where rites connected with her former cult are still performed for fertility on Midsummer eve.
