Brittany have forms more slender and smaller in stature than those of the living;[105] and herein we find one of the factors which supporters of the Pygmy Theory would emphasize, but it is thoroughly psychical. Old Breton farmers after death return to their farms, as though come from Fairyland; and sometimes they even take a turn at the ploughing.[105] As in Ireland, so in Brittany, the day belongs to the living, and the night, when a mortal is safer indoors than out, to spirits and the dead.[105] The Bretons take great care not to counterfeit the dead nor to speak slightingly of them,[106] for, like fairies, they know all that is done by mortals, and can hear all that is said about them, and can take revenge. Just as in the case of all fairies and goblins, the dead disappear at first cock-crow.[107] The world of the dead, like the land of Faerie or the Otherworld, may be underground, in the air, in a hill or mountain like a fairy palace, under a river or sea, and even on an island out amid the ocean.[107] As other Celts do against evil spirits and fairies, the Breton peasants use magic against evil souls of the dead,[108] and the priests use exorcisms. The Breton realm of the dead equally with the Irish Fairyland is an invisible world peopled by other kinds of spirits besides disembodied mortals and fairies.[109] The dead haunt houses just as Robin Good-fellows and brownies, or pixies and goblins, generally do. The dead are fond of frequenting cross-roads, and so are all sorts of fairies. In Brittany one must always guard against the evil dead, in Cornwall against pixies, in other Celtic lands against different kinds of fairies. In Ireland and Scotland there is the banshee, in Wales the death-candle, in Brittany the _Ankou_ or king of the dead, to foretell a death. And as the banshee wails before the ancestral mansion, so the _Ankou_ sounds its doleful cry before the door of the one it calls.[109] There seems not to be a family in the Carnac region of the Morbihan without some tradition of a warning coming before the death of one of its members. In Ireland only certain families have a banshee, but in Brittany all families. Professor Le Braz has devoted a large part of his work on _La Légende de la Mort_ to these Breton death-warnings or _intersignes_. They may be shades of the dead under many aspects--ghostly hands, or ghosts of inanimate objects. They may come by the fall of objects without known cause; by a magpie resting on a roof--just as in Ireland; by the crowing of cocks, and the howling of dogs at night. They may be death-candles or torches, dreams, peculiar bodily sensations, images in water, phantom funerals, and death-chariots or death-coaches as in Wales.
