Akerbeltz

Also Known As: Basque aker, “he-goat”, and beltz, “black”: “the black he-goat”; also plain Aker
Region/Culture: Southern Europe
Mythos: Basque Mythology
Primary Type/Nature: Gods and Deities
Mythical Attributes: A spirit that heals and guards domestic animals, working its protection through a living black he-goat kept among the herd.
Role in Mythos: In José Miguel de Barandiarán’s account of Basque belief, Akerbeltz is a protective numen closely tied to the goddess Mari, and the same black goat became the presiding figure of the witches’ gathering in the trial records of the early 1600s.
Relation to Humans: Farming households across the Basque Country kept a black he-goat in the stable so that its protection would keep sickness away from the cattle and sheep. Witch-hunters of the seventeenth century turned the same animal into the devil that the accused were said to worship.

The cows shift in the dark and the stable is warm with their breath. Among them, tied where the herd can smell it, stands a black billy goat, rank enough that the whole low room carries its odour. Nobody keeps it for milk or meat. It is there so that the cattle will not fall ill.

That goat is the whole visible body of Akerbeltz. The name is simply a description in Basque: aker is a he-goat and beltz is black. What made the black he-goat more than livestock was a belief that a protective spirit worked through it, and that belief comes down to us in two very different kinds of record. One is the patient notebook work of Basque ethnographers in the twentieth century. The other is the testimony extracted by witch-hunters in 1609 and 1610.

The ethnographic record is plain and surprisingly consistent. At Ainhoa in Labourd, José Miguel de Barandiarán noted in 1955 that some shepherds and stockmen raised a black he-goat in the stable for protection. The Atlas Etnográfico de Vasconia, which gathered village-by-village surveys across the Basque provinces, found the same habit almost everywhere it looked. At Sara the he-goat, the nanny goat and the donkey were all counted as animals that protect whatever else is kept in the stable. In Astigarraga, Getaria and Elgoibar farmers placed a goat, akerra, among their cows so that they would not sicken, naming lung disease, udder infection and miscarriage among the troubles it kept away. At Hondarribia people said that if a billy goat lived in the cowshed the disease called lipu beltza would not come in, because of its smell. In Larraun shepherds kept one because it drew all the harm onto itself. In the Valle de Ayala a farmer tied a goat in his stable as late as 1996, after his cattle caught brucellosis, and reckoned it worked.

Most of those informants spoke of a goat, not a god. The step from animal to spirit was taken, on the page at least, by Barandiarán, the priest and ethnographer whose Mitología vasca (1960) remains the standard account of Basque belief. In his words, the numen called Akerbeltz has healing powers and a beneficent influence over the animals entrusted to its care, and it exerts that influence through its symbol, the he-goat. That is why, he wrote, households hoping to keep sickness from their herd raise a he-goat in the stable, and it must be black, an aker beltz, so that the protection works more strongly. He went further and tied the figure to Mari, the great goddess of Basque tradition, describing the black goat as a genius that in some respects seems to stand in for Mari herself, and recording that every black kid was considered a symbol of her. Fuller summaries built on his work add that Akerbeltz dwells underground, commands many lesser spirits and raises storms. Whose picture this is matters. The farm practice is recorded in dozens of villages; the named, ruling spirit behind it is Barandiarán’s synthesis of that practice and of scattered beliefs about Mari, set down in the twentieth century.

The second record is darker. In 1609 the magistrate Pierre de Lancre was sent into Labourd to root out witchcraft, and in four months of hearings he condemned dozens of people. His book Tableau de l’inconstance des mauvais anges et démons (1612) placed the witches’ sabbath on a heath he called the Lanne de bouc, the goat’s moor, and filled it with a goat-shaped devil. One witness, Jean d’Aguerre, told the court that the devil came to the gathering as a goat. De Lancre wrote of witches who loved a stinking goat, caressed it, and coupled with it. Across the mountains in 1610, the Spanish Inquisition’s tribunal at Logroño tried the people of Zugarramurdi and the Baztan valley on the same kind of charges. The Basque word for the witches’ meeting, akelarre, is usually explained as the he-goat’s meadow.

Put the two records side by side and the shape is hard to miss. The animal that the farmhouse trusted with its cattle is the animal the courts made into Satan. Twentieth-century folklorists read the sabbath goat as an old protective spirit that Christian authority had turned into a devil. That reading is plausible, and it may be right. It is also an interpretation, and the trial records themselves never use the name Akerbeltz.

There is one more possible trace, much older and much less certain. From the Haute-Garonne, on the French side of the Pyrenees, comes a Roman-period altar dedicated to a god called Aherbelste. Its original find-spot has been lost; the candidates are Aulon, Saint-Aventin, or most probably Landorthe. Some have read the name as aker plus a word for black, which would make it a black-goat god more than a millennium and a half before Barandiarán. Others derive the first part from a word for stone instead. The altar is real. The link is a guess.

What the goat could do is modest and specific. It kept disease out of the stable, drew sickness onto itself, and cured the animals in its charge. Its limits were just as practical. The protection lived in a single mortal animal, and it had to be the right colour: a goat that was not black, by Barandiarán’s account, did the work less well. No source gives Akerbeltz a myth of its own, a birth, or a death. Its entire power sat in a smelly animal at the end of a rope, which is perhaps why it lasted so long.

Frequently Asked Questions

What is Akerbeltz?

Akerbeltz is a protective spirit of Basque folk belief whose name means “black he-goat.” It was believed to guard and heal domestic animals through a living black billy goat kept in the stable. The ethnographer José Miguel de Barandiarán described it as a numen closely linked to the goddess Mari.

Why did Basque farmers keep a black goat in the stable?

Basque farmers kept a black he-goat among their cattle and sheep to keep disease away from the herd. Village surveys in the Atlas Etnográfico de Vasconia record the practice from Ainhoa, Sara, Hondarribia, Larraun and many other places, with some saying the goat’s smell kept illness out and others that it drew harm onto itself. Barandiarán wrote that the goat had to be black for the protection of Akerbeltz to work best.

Is Akerbeltz the devil?

Akerbeltz was not originally the devil, but witch-hunters made the black goat into one. During the Labourd witch trials of 1609, Pierre de Lancre recorded testimony that the devil appeared at the witches’ sabbath as a goat. Twentieth-century folklorists read this as an older protective spirit turned into a demon by Christian authorities, although the trial records never use the name Akerbeltz.

What is the connection between Akerbeltz and Mari?

José Miguel de Barandiarán described the black he-goat as a genius that in some respects seems to stand in for Mari, the chief goddess of Basque tradition. He also recorded that every black kid was considered a symbol of Mari.

Is Akerbeltz mentioned in Roman inscriptions?

Possibly, but the link is uncertain. A Roman-period altar from the Haute-Garonne is dedicated to a god named Aherbelste, and some have read that name as meaning “black goat.” Others derive it from a word for stone, and the altar’s exact find-spot has been lost.
