The Study of Celtic Folklore, Mythology & Dogma. John Arnott MacCulloch

not be Celtic, based on some myth now lost to us. The Celts had a cult of human heads, and fixed them up on their houses in order to obtain the protection of the ghost. Bodies or heads of dead warriors had a protective influence on their land or tribe, and myth told how the head of the god Bran saved his country from invasion. In other myths human heads speak after being cut off.¹⁰² It might thus easily have been believed that the representation of a god's head had a still more powerful protective influence, especially when it was triplicated, thus looking in all directions, like Janus.

      The significance of the triad on these monuments is uncertain but since the supporting divinities are now male, now female, now male and female, it probably represents myths of which the horned or three-headed god was the central figure. Perhaps we shall not be far wrong in regarding such gods, on the whole, as Cernunnos, a god of abundance to judge by his emblems, and by the cornucopia held by his companions, probably divinities of fertility. In certain cases figures of squatting and horned goddesses with cornucopia occur.¹⁰³ These may be consorts of Cernunnos, and perhaps preceded him in origin. We may also go further and see in this god of abundance and fertility at once an Earth and an Under-earth god, since earth and under-earth are much the same to primitive thought, and fertility springs from below the earth's surface. Thus Cernunnos would be another form of the Celtic Dispater. Generally speaking, the images of Cernunnos are not found where those of the god with the hammer (Dispater) are most numerous. These two types may thus be different local forms of Dispater. The squatting attitude of Cernunnos is natural in the image of the ancestor of a people who squatted. As to the symbols of plenty, we know that Pluto was confounded with Plutus, the god of riches, because corn and minerals came out of the earth, and were thus the gifts of an Earth or Under-earth god. Celtic myth may have had the same confusion.

      On a Paris altar and on certain steles a god attacks a serpent with a club. The serpent is a chthonian animal, and the god, called Smertullos, may be a Dispater.¹⁰⁴ Gods who are anthropomorphic forms of earlier animal divinities, sometimes have the animals as symbols or attendants, or are regarded as hostile to them. In some cases Dispater may have outgrown the serpent symbolism, the serpent being regarded locally as his foe; this assumes that the god with the club is the same as the god with the hammer. But in the case of Cernunnos the animal remained as his symbol.

      Dispater was a god of growth and fertility, and besides being lord of the underworld of the dead, not necessarily a dark region or the abode of "dark" gods as is so often assumed by writers on Celtic religion, he was ancestor of the living. This may merely have meant that, as in other mythologies, men came to the surface of the earth from an underground region, like all things whose roots struck deep down into the earth. The lord of the underworld would then easily be regarded as their ancestor.¹⁰⁵

      3. The hammer and the cup are also the symbols of a god called Silvanus, identified by M. Mowat with Esus,¹⁰⁶ a god represented cutting down a tree with an axe. Axe and hammer, however, are not necessarily identical, and the symbols are those of Dispater, as has been seen. A purely superficial connection between the Roman Silvanus and the Celtic Dispater may have been found by Gallo-Roman artists in the fact that both wear a wolf-skin, while there may once have been a Celtic wolf totem-god of the dead.¹⁰⁷ The Roman god was also associated with the wolf. This might be regarded as one out of many examples of a mere superficial assimilation of Roman and Celtic divinities, but in this case they still kept certain symbols of the native Dispater—the cup and hammer. Of course, since the latter was also a god of fertility, there was here another link with Silvanus, a god of woods and vegetation. The cult of the god was widespread—in Spain, S. Gaul, the Rhine provinces, Cisalpine Gaul, Central Europe and Britain. But one inscription gives the name Selvanos, and it is not impossible that there was a native god Selvanus. If so, his name may have been derived from selva, "possession," Irish sealbh, "possession," "cattle," and he may have been a chthonian god of riches, which in primitive communities consisted of cattle.¹⁰⁸ Domestic animals, in Celtic mythology, were believed to have come from the god's land. Selvanus would thus be easily identified with Silvanus, a god of flocks.

      Thus the Celtic Dispater had various names and forms in different regions, and could be assimilated to different foreign gods. Since Earth and Under-earth are so nearly connected, this divinity may once have been an Earth-god, and as such perhaps took the place of an earlier Earth-mother, who now became his consort or his mother. On a monument from Salzbach, Dispater is accompanied by a goddess called Aeracura, holding a basket of fruit, and on another monument from Ober-Seebach, the companion of Dispater holds a cornucopia. In the latter instance Dispater holds a hammer and cup, and the goddess may be Aeracura. Aeracura is also associated with Dispater in several inscriptions.¹⁰⁹ It is not yet certain that she is a Celtic goddess, but her presence with this evidently Celtic god is almost sufficient proof of the fact. She may thus represent the old Earth-goddess, whose place the native Dispater gradually usurped.

      Lucan mentions a god Esus, who is represented on a Paris altar as a woodman cutting down a tree, the branches of which are carried round to the next side of the altar, on which is represented a bull with three cranes—Tarvos Trigaranos. The same figure, unnamed, occurs on another altar at Trèves, but in this case the bull's head appears in the branches, and on them sit the birds. M. Reinach applies one formula to the subjects of these altars—"The divine Woodman hews the Tree of the Bull with Three Cranes."¹¹⁰ The whole represents some myth unknown to us, but M. D'Arbois finds in it some allusion to events in the Cúchulainn saga. To this we shall return.¹¹¹ Bull and tree are perhaps both divine, and if the animal, like the images of the divine bull, is three-horned, then the three cranes (garanus, "crane") may be a rebus for three-horned (trikeras), or more probably three-headed (trikarenos).¹¹² In this case woodman, tree, and bull might all be representatives of a god of vegetation. In early ritual, human, animal, or arboreal representatives of the god were periodically destroyed to ensure fertility, but when the god became separated from these representatives, the destruction or slaying was regarded as a sacrifice to the god, and myths arose telling how he had once slain the animal. In this case, tree and bull, really identical, would be mythically regarded as destroyed by the god whom they had once represented. If Esus was a god of vegetation, once represented by a tree, this would explain why, as the scholiast on Lucan relates, human sacrifices to Esus were suspended from a tree. Esus was worshipped at Paris and at Trèves; a coin with the name Æsus was found in England; and personal names like Esugenos, "son of Esus," and Esunertus, "he who has the strength of Esus," occur in England, France, and Switzerland.¹¹³ Thus the cult of this god may have been comparatively widespread. But there is no evidence that he was a Celtic Jehovah or a member, with Teutates and Taranis, of a pan-Celtic triad, or that this triad, introduced by Gauls, was not accepted by the Druids.¹¹⁴ Had such a great triad existed, some instance of the occurrence of the three names on one inscription would certainly have been found. Lucan does not refer to the gods as a triad, nor as gods of all the Celts, or even of one tribe. He lays stress merely on the fact that they were worshipped with human sacrifice, and they were apparently more or less well-known local gods.¹¹⁵

      The insular Celts believed that some of their gods lived on or in hills. We do not know whether such a belief was entertained by the Gauls, though some of their deities were worshipped on hills, like the Puy de Dôme. There is also evidence of mountain worship among them. One inscription runs, "To the Mountains"; a god of the Pennine Alps, Poeninus, was equated with Juppiter; and the god of the Vosges mountains was called Vosegus, perhaps still surviving in the giant supposed to haunt them.¹¹⁶

      Certain grouped gods, Dii Casses, were worshipped by Celts on the right bank of the Rhine, but nothing is known regarding their functions, unless they were road gods. The name means "beautiful" or "pleasant," and Cassi appears in personal and tribal names, and also in Cassiterides, an early name of Britain, perhaps signifying that the new lands were "more beautiful" than those the Celts had left. When tin was discovered in Britain, the Mediterranean traders called it (chassiteros), after the name of the place where it was found, as cupreus, "copper," was so called from Cyprus.¹¹⁷

      Many local tutelar divinities were also worshipped. When a new settlement was founded, it was placed under the protection of a tribal god, or the name of some divinised river on whose banks the village
