Many local gods were identified with Apollo both in his capacity of god of healing and also that of god of light.9 The two functions are not incompatible, and this is suggested by the name Grannos, god of thermal springs both in Britain and on the Continent. The name is connected with a root which gives words meaning "burning," "shining," etc., and from which comes also Irish grian, "sun." The god is still remembered in a chant sung round bonfires in Auvergne. A sheaf of corn is set on fire, and called "Granno mio," while the people sing, "Granno, my friend; Granno, my father; Granno, my mother."10 Another god of thermal springs was Borvo, Bormo, or Bormanus, whose name is derived from borvo, whence Welsh berw, "boiling," and is evidently connected with the bubbling of the springs.11 Votive tablets inscribed Grannos or Borvo show that the offerers desired healing for themselves or others.
The name Belenos found over a wide area, but mainly in Aquileia, comes from belo-s, bright, and probably means "the shining one." It is thus the name of a Celtic sun-god, equated with Apollo in that character. If he is the Belinus referred to by Geoffrey of Monmouth,12 his cult must have extended into Britain from the Continent, and he is often mentioned by classical writers, while much later Ausonius speaks of his priest in Gaul.13 Many place and personal names point to the popularity of his cult, and inscriptions show that he, too, was a god of health and of healing-springs. The plant Belinuntia was called after him and venerated for its healing powers.14 The sun-god's functions of light and fertility easily passed over into those of health-giving, as our study of Celtic festivals will show.
A god with the name Maponos, connected with words denoting "youthfulness," is found in England and Gaul, equated with Apollo, who himself is called Bonus Puer in a Dacian inscription. Another god Mogons or Mogounos, whose name is derived from Mago, "to increase," and suggests the idea of youthful strength, may be a form of the sun-god, though some evidence points to his having been a sky-god.15
The Celtic Apollo is referred to by classical writers. Diodorus speaks of his circular temple in an island of the Hyperboreans, adorned with votive offerings. The kings of the city where the temple stood, and its overseers, were called "Boreads," and every nineteenth year the god appeared dancing in the sky at the spring equinox.16 The identifications of the temple with Stonehenge and of the Boreads with the Bards are quite hypothetical. Apollonius says that the Celts regarded the waters of Eridanus as due to the tears of Apollo—probably a native myth attributing the creation of springs and rivers to the tears of a god, equated by the Greeks with Apollo.17 The Celtic sun-god, as has been seen, was a god of healing springs.
Some sixty names or titles of Celtic war-gods are known, generally equated with Mars.18 These were probably local tribal divinities regarded as leading their worshippers to battle. Some of the names show that these gods were thought of as mighty warriors, e.g. Caturix, "battle-king," Belatu-Cadros—a common name in Britain—perhaps meaning "comely in slaughter,"19 and Albiorix, "world-king."20 Another name, Rigisamus, from rix and samus, "like to," gives the idea of "king-like."21
Toutatis, Totatis, and Tutatis are found in inscriptions from Seckau, York, and Old Carlisle, and may be identified with Lucan's Teutates, who with Taranis and Esus mentioned by him, is regarded as one of three pan-Celtic gods.22 Had this been the case we should have expected to find many more inscriptions to them. The scholiast on Lucan identifies Teutates now with Mars, now with Mercury. His name is connected with teuta, "tribe," and he is thus a tribal war-god, regarded as the embodiment of the tribe in its warlike capacity.
Neton, a war-god of the Accetani, has a name connected with Irish nia, "warrior," and may be equated with the Irish war-god Nét. Another god, Camulos, known from British and continental inscriptions, and figured on British coins with warlike emblems, has perhaps some connection with Cumal, father of Fionn, though it is uncertain whether Cumal was an Irish divinity.23
Another god equated with Mars is the Gaulish Braciaca, god of malt. According to classical writers, the Celts were drunken race, and besides importing quantities of wine, they made their own native drinks, e.g. (chourmi), the Irish cuirm, and braccat, both made from malt (braich).24 These words, with the Gaulish brace, "spelt,"25 are connected with the name of this god, who was a divine personification of the substance from which the drink was made which produced, according to primitive ideas, the divine frenzy of intoxication. It is not clear why Mars should have been equated with this god.
Cæsar says that the Celtic Juppiter governed heaven. A god who carries a wheel, probably a sun-god, and another, a god of thunder, called Taranis, seem to have been equated with Juppiter. The sun-god with the wheel was not equated with Apollo, who seems to have represented Celtic sun-gods only in so far as they were also gods of healing. In some cases the god with the wheel carries also a thunderbolt, and on some altars, dedicated to Juppiter, both a wheel and a thunderbolt are figured. Many races have symbolised the sun as a circle or wheel, and an old Roman god, Summanus, probably a sun-god, later assimilated to Juppiter, had as his emblem a wheel. The Celts had the same symbolism, and used the wheel symbol as an amulet,26 while at the midsummer festivals blazing wheels, symbolising the sun, were rolled down a slope. Possibly the god carries a thunderbolt because the Celts, like other races, believed that lightning was a spark from the sun.
Three divinities have claims to be the god whom Cæsar calls Dispater—a god with a hammer, a crouching god called Cernunnos, and a god called Esus or Silvanus. Possibly the native Dispater was differently envisaged in different districts, so that these would be local forms of one god.
1. The god Taranis mentioned by Lucan is probably the Taranoos and Taranucnos of inscriptions, sometimes equated with Juppiter.27 These names are connected with Celtic words for "thunder"; hence Taranis is a thunder-god. The scholiasts on Lucan identify him now with Juppiter, now with Dispater. This latter identification is supported by many who regard the god with the hammer as at once Taranis and Dispater, though it cannot be proved that the god with the hammer is Taranis. On one inscription the hammer-god is called Sucellos; hence we may regard Taranis as a distinct deity, a thunder-god, equated with Juppiter, and possibly represented by the Taran of the Welsh tale of Kulhwych.28
Primitive men, whose only weapon and tool was a stone axe or hammer, must have regarded it as a symbol of force, then of supernatural force, hence of divinity. It is represented on remains of the Stone Age, and the axe was a divine symbol to the Mycenæans, a hieroglyph of Neter to the Egyptians, and a worshipful object to Polynesians and Chaldeans.
