These goddesses may have been thought of as rushing through the forest with an attendant train, since in later times Diana, with whom they were completely assimilated, became, like Holda, the leader of the "furious host" and also of witches' revels.⁷⁶ The Life of Cæsarius of Arles speaks of a "demon" called Diana by the rustics. A bronze statuette represents the goddess riding a wild boar,⁷⁷ her symbol and, like herself, a creature of the forest, but at an earlier time itself a divinity of whom the goddess became the anthropomorphic form.

Goddesses, the earlier spirits of the waters, protected rivers and springs, or were associated with gods of healing wells. Dirona or Sirona is associated with Grannos mainly in Eastern Gaul and the Rhine provinces, and is sometimes represented carrying grapes and grain.⁷⁸ Thus this goddess may once have been connected with fertility, perhaps an Earth-mother, and if her name means "the long-lived,"⁷⁹ this would be an appropriate title for an Earth-goddess. Another goddess, Stanna, mentioned in an inscription at Perigueux, is perhaps "the standing or abiding one," and thus may also have been Earth-goddess.⁸⁰ Grannos was also associated with the local goddesses Vesunna and Aventia, who gave their names to Vesona and Avanche. His statue also stood in the temple of the goddess of the Seine, Sequana.⁸¹ With Bormo were associated Bormana in Southern Gaul, and Damona in Eastern Gaul—perhaps an animal goddess, since the root of her name occurs in Irish dam, "ox," and Welsh dafad, "sheep." Dea Brixia was the consort of Luxovius, god of the waters of Luxeuil. Names of other goddesses of the waters are found on ex votos and plaques which were placed in or near them. The Roman Nymphæ, sometimes associated with Bormo, were the equivalents of the Celtic water-goddesses, who survived in the water-fairies of later folk-belief. Some river-goddesses gave their names to many rivers in the Celtic area—the numerous Avons being named from Abnoba, goddess of the sources of the Danube, and the many Dees and Dives from Divona. Clota was goddess of the Clyde, Sabrina had her throne "beneath the translucent wave" of the Severn, Icauna was goddess of the Yonne, Sequana of the Seine, and Sinnan of the Shannon.

In some cases forests were ruled by goddesses—that of the Ardennes by Dea Arduinna, and the Black Forest, perhaps because of the many waters in it, by Dea Abnoba.⁸² While some goddesses are known only by being associated with a god, e.g. Kosmerta with Mercury in Eastern Gaul, others have remained separate, like Epona, perhaps a river-goddess merged with an animal divinity, and known from inscriptions as a horse-goddess.⁸³ But the most striking instance is found in the grouped goddesses.

Of these the Deoe Matres, whose name has taken a Latin form and whose cult extended to the Teutons, are mentioned in many inscriptions all over the Celtic area, save in East and North-West Gaul.⁸⁴ In art they are usually represented as three in number, holding fruit, flowers, a cornucopia, or an infant. They were thus goddesses of fertility, and probably derived from a cult of a great Mother-goddess, the Earth personified. She may have survived as a goddess Berecynthia; worshipped at Autun, where her image was borne through the fields to promote fertility, or as the goddesses equated with Demeter and Kore, worshipped by women on an island near Britain.⁸⁵ Such cults of a Mother-goddess lie behind many religions, but gradually her place was taken by an Earth-god, the Celtic Dispater or Dagda, whose consort the goddess became. She may therefore be the goddess with the cornucopia on monuments of the horned god, or Aeracura, consort of Dispater, or a goddess on a monument at Epinal holding a basket of fruit and a cornucopia, and accompanied by a ram's-headed serpent.⁸⁶ These symbols show that this goddess was akin to the Matres. But she sometimes preserved her individuality, as in the case of Berecynthia and the Matres, though it is not quite clear why she should have been thus triply multiplied. A similar phenomenon is found in the close connection of Demeter and Persephone, while the Celts regarded three as a sacred number. The primitive division of the year into three seasons—spring, summer, and winter—may have had its effect in triplicating a goddess of fertility with which the course of the seasons was connected.⁸⁷ In other mythologies groups of three goddesses are found, the Hathors in Egypt, the Moirai, Gorgons, and Graiæ of Greece, the Roman Fates, and the Norse Nornæ, and it is noticeable that the Matres were sometimes equated with the Parcæ and Fates.⁸⁸

In the Matres, primarily goddesses of fertility and plenty, we have one of the most popular and also primitive aspects of Celtic religion. They originated in an age when women cultivated the ground, and the Earth was a goddess whose cult was performed by priestesses. But in course of time new functions were bestowed on the Matres. Possibly river-goddesses and others are merely mothers whose functions have become specialised. The Matres are found as guardians of individuals, families, houses, of towns, a province, or a whole nation, as their epithets in inscriptions show. The Matres Domesticæ are household goddesses; the Matres Treveræ, or Gallaicæ, or Vediantæ, are the mothers of Trèves, of the Gallaecæ, of the Vediantii; the Matres Nemetiales are guardians of groves. Besides presiding over the fields as Matres Campestræ they brought prosperity to towns and people.⁸⁹ They guarded women, especially in childbirth, as ex votos prove, and in this aspect they are akin to the Junones worshipped also in Gaul and Britain. The name thus became generic for most goddesses, but all alike were the lineal descendants of the primitive Earth-mother.⁹⁰

Popular superstition has preserved the memory of these goddesses in the three bonnes dames, dames blanches, and White Women, met by wayfarers in forests, or in the three fairies or wise women of folk-tales, who appear at the birth of children. But sometimes they have become hateful hags. The Matres and other goddesses probably survived in the beneficent fairies of rocks and streams, in the fairy Abonde who brought riches to houses, or Esterelle of Provence who made women fruitful, or Aril who watched over meadows, or in beings like Melusine, Viviane, and others.⁹¹ In Gallo-Roman Britain the cult of the Matres is found, but how far it was indigenous there is uncertain. A Welsh name for fairies, Y Mamau, "the Mothers," and the phrase, "the blessing of the Mothers" used of a fairy benediction, may be a reminiscence of such goddesses.⁹² The presence of similar goddesses in Ireland will be considered later.⁹³ Images of the Matres bearing a child have sometimes been taken for those of the Virgin, when found accidentally, and as they are of wood blackened with age, they are known as Vierges Noires, and occupy an honoured place in Christian sanctuaries. Many churches of Nôtre Dame have been built on sites where an image of the Virgin is said to have been miraculously found—the image probably being that of a pagan Mother. Similarly, an altar to the Matres at Vaison is now dedicated to the Virgin as the "good Mother."⁹⁴

In inscriptions from Eastern and Cisalpine Gaul, and from the Rhine and Danube region, the Matronæ are mentioned, and this name is probably indicative of goddesses like the Matres.⁹⁵
