Overview

Though the Celtic world at its height covered much of western and central Europe, it was not politically unified, nor was there any substantial central source of cultural influence or homogeneity; as a result, there was a great deal of variation in local practices of
Celtic religion (although certain motifs, for example, the god
Lugh

, appear to have diffused throughout the Celtic world). Inscriptions of more than three hundred deities, often equated with their Roman counterparts, have survived, but of these most appear to have been ''
genii locorum'', local or tribal gods, and few were widely worshiped. However, from what has survived of Celtic mythology, it is possible to discern commonalities that hint at a more unified pantheon than is often given credit.
The nature and functions of these ancient gods can be deduced from their names, the location of their inscriptions, their
iconography, the
Roman gods they are equated with, and similar figures from later bodies of Celtic mythology.
Celtic mythology is found in distinct if related, subgroups, largely corresponding to the branches of the

Irish mythology
Irish mythology is the largest surviving branch of Celtic mythology. It was originally
passed down orally in the
prehistoric era. Many myths were later
written down in the
early medieval era by Christian scribes, who modified and Christianized them to some extent.
The myths are conventionally grouped into '
cycles'. The
Mythological Cycle, or Cycle of the Gods, consists of tales and poems about the god-like
Túatha Dé Danann and other mythical races. Many of the Tuath Dé are thought to represent Irish deities.
They are often depicted as kings, queens, druids, bards, warriors, heroes, healers and craftsmen who have supernatural powers. Prominent members of the Tuath Dé include
The Dagda ("the great god"), who seems to have been the chief god;
The Morrígan ("the great queen" or "phantom queen"), a triple goddess associated with war, fate and sovereignty;

The
Ulster Cycle consists of heroic legends about the
Ulaid. It focuses on the mythical Ulster king
Conchobar mac Nessa and his court at
Emain Macha, the hero
Cú Chulainn, and their conflict with the
Connachta and queen
Medb. The longest and most important tale is the epic ''
Táin Bó Cúailnge'' (Cattle Raid of Cooley).
The
Fianna Cycle is about the exploits of the mythical hero
Finn and his
warrior band the
Fianna, including the lengthy ''
Acallam na Senórach'' ("Tales of the Elders").
The
Kings' Cycle comprises legends about historical and semi-historical kings of Ireland (such as ''
Buile Shuibhne'', "The Madness of King Sweeny"), and tales about the origins of dynasties and peoples.
There are also mythical texts that do not fit into any of the cycles; these include the ''
echtrai'' tales of journeys to
the Otherworld (such as ''
The Voyage of Bran''), and the ''
Dindsenchas'' ("lore of places"). Some written material has not survived, and many more myths were probably never written down.
Welsh mythology

Important reflexes of British mythology appear in the
Four Branches of the Mabinogi, especially in the names of several characters, such as
Rhiannon,
Teyrnon, and
Brân the Blessed
Brân the Blessed ( or ''Brân Fendigaidd'', literally "Blessed Crow") is a giant and king of Britain in Welsh mythology. He appears in several of the Welsh Triads, but his most significant role is in the Second Branch of the Mabinogi, '' ...
(''Bendigeidfran'', "Bran
rowthe Blessed"). Other characters, in all likelihood, derive from mythological sources, and various episodes, such as the appearance of
Arawn, a king of the Otherworld seeking the aid of a mortal in his own feuds, and the tale of the hero who cannot be killed except under seemingly contradictory circumstances, can be traced throughout
Proto-Indo-European mythology
Proto-Indo-European mythology is the body of myths and deities associated with the Proto-Indo-Europeans, speakers of the hypothesized Proto-Indo-European language. Although the mythological motifs are not directly attested – since Proto-Ind ...
. The children of
Llŷr ("Sea" = Irish
Ler) in the Second and Third Branches, and the children of
Dôn (
Danu in Irish and earlier Indo-European tradition) in the Fourth Branch are major figures, but the tales themselves are not primary mythology.
While further mythological names and references appear elsewhere in Welsh narrative and tradition, especially in the tale of ''
Culhwch and Olwen'', where we find, for example,
Mabon ap Modron ("Divine Son of the Divine Mother"), and in the collected
Welsh Triads, not enough is known of the British mythological background to reconstruct either a narrative of creation or a coherent pantheon of British deities. Though there is much in common with Irish myth, there may have been no unified British mythological tradition ''per se''. Whatever its ultimate origins, the surviving material has been put to good use in the service of literary masterpieces that address the cultural concerns of

Remnants of Gaulish and other mythology

The Celts also worshiped a number of deities of which little more is known than
their names. Classical writers preserve a few fragments of legends or myths that may possibly be Celtic.
According to the Syrian rhetorician
Lucian,
Ogmios was supposed to lead a band of men chained by their ears to his tongue as a symbol of the strength of his eloquence.

Lucan mentions the gods
Taranis,
Teutates and
Esus
Esus is a Celtic god known from iconographic, epigraphic, and literary sources.
The 1st-century CE Roman poet Lucan's epic ''Pharsalia'' mentions Esus, Taranis, and Teutates as gods to whom the Gauls sacrificed humans. This rare mention of Cel ...

Anguiped (a snake-legged human-like figure). The

Along with dedications giving us god names, there are also deity representations to which no name has yet been attached. Among these are images of a three-headed or three-faced god, a squatting god, a god with a snake, a god with a wheel, and a horseman with a kneeling giant.
Some of these images can be found in

in Britain,
indicating the symbols were both pre-Roman and widely spread across Celtic culture. The distribution of some of the images has been mapped and shows a pattern of central concentration of an image along with a wide scatter, indicating these images were most likely attached to specific tribes and were distributed from some central point of tribal concentration outward along the lines of trade. The image of the three-headed god is centrally concentrated among the Belgae, between the Oise, Marne, and Moselle rivers. The horseman with the kneeling giant is centered on either side of the Rhine. These examples seem to indicate regional preferences for a common image stock.
Julius Caesar on Celtic gods and their significance

The classic entry about the Celtic gods of Gaul is by
Julius Caesar
Gaius Julius Caesar (12 or 13 July 100 BC – 15 March 44 BC) was a Roman general and statesman. A member of the First Triumvirate, Caesar led the Roman armies in the Gallic Wars before defeating his political rival Pompey in Caesar's civil wa ...
's history of his war in Gaul. In this he names the five principal gods worshiped in Gaul (according to the
practice of his time, he gives the names of the closest equivalent Roman gods) and describes their roles:
Mercury was the most venerated of all the deities, and numerous representations of him were to be discovered. Mercury was seen as the originator of all the arts (and is often taken to refer to
Lugus for this reason), the supporter of adventurers and of traders, and the mightiest power concerning trade and profit.
Next the Gauls revered
Apollo
Apollo is one of the Twelve Olympians, Olympian deities in Ancient Greek religion, ancient Greek and Ancient Roman religion, Roman religion and Greek mythology, Greek and Roman mythology. Apollo has been recognized as a god of archery, mu ...

Jupiter
Jupiter is the fifth planet from the Sun and the List of Solar System objects by size, largest in the Solar System. It is a gas giant with a Jupiter mass, mass more than 2.5 times that of all the other planets in the Solar System combined a ...
, and
Minerva. Among these divinities, Caesar described the Gauls as holding roughly equal views as other populations: Apollo dispels sickness, Minerva encourages skills, Jupiter governs the skies, and Mars influences warfare. MacBain argues that Apollo corresponds to
Irish Lugh, Mercury to
Manannan mac Lir, Jupiter to
the Dagda, Mars to
Neit, and Minerva to
Brigit.
In addition to these five, Caesar mentions that the Gauls traced their ancestry to
a god he likened to Dis Pater (possibly Irish
Donn).
