The
Gauls divided the universe into three parts:
Albios ("heaven, white-world, upper-world"),
Bitu ("world of the living beings"), and
Dubnos ("hell, lower-world, black-world").;; According to
Lucan, the
Gaulish druids believed that the soul went to an Otherworld, which he calls by the Latin name
Orbis alius, before being
reincarnated.
Greco-Roman geographers tell us about Celtic belief in islands consecrated to gods and heroes. Among them were
Anglesey (
Môn), off the north coast of Wales, which was the sacred isle of the druids of Britain; the
Scilly isles, where archaeological remains of proto-historical temples have been found; and some of the
Hebrides, which were, in the Gaelic tradition, home to ghosts and demons: on one of them,
Skye, the Irish hero
Cúchulainn was taught by the warrior woman
Scathach. Byzantine scholar
Procopius of Caesarea described the Otherworld of the ancient Gauls. He said it was thought that the land of the dead lay west of Great Britain. The Continental Celtic myths told that once the souls of the dead had left their bodies, they traveled to the northwest coast of
Gaul and took a boat toward Britain. When they crossed the
Channel, the souls went to the homes of the fishermen, and knocked desperately at their doors. The fishermen then went out of their houses and led the souls to their destination in ghostly ships. There are still remains of those beliefs in the folklore of
Brittany, where the name
Bag an Noz is used to denote those ships who carry the dead to their goal:
Anatole Le Braz describes in his book
La légende de la mort chez les Bretons armoricains the existence of souls' processions which make their way toward coastal places like Laoual, to start their last travel from there. In
Asturian mythology, there are many stories which describe human encounters with
xanas, fairies which are dancing around a chief fairy, the
Xana Mega, or the "Queen of Fairies", known as in
Galicia. The
castro of Altamira is said to hide an enormous underground realm which is ruled by a royal couple, and whose entrance is found some place on the hill. ==Modern treatments==
