Graciana de Barrenechea

Francisco Goya's The Incantation: the witch in yellow may represent Graciana de Barrenechea. Graciana de Barrenechea (Basque: ; –1610) was a Basque woman accused of being a leading figure in devil-worship during the Basque witch trials. She died in prison prior to the 1610 auto-da-fé at Logroño, with her remains and an effigy burned instead.

Family Barrenechea's first husband was Juanes (or Joanes) de Yriarte, a shepherd. They had three daughters, including Estevanía and María de Yriarte; Estevanía married another shepherd, Juanes (or Joanes) de Goiburu, the son of a leading shepherd, Miguel de Goiburu.

They all lived in and around Zugarramurdi during the Basque witch trials, with scholars Mikel Azurmendi and Emma Wilby theorising that this extended family was a focal point of witchcraft accusations due to previously fighting for village freedom from the nearby Urdax monastery (which became the authority in local witch-hunting): Miguel was accused of being the ringleader of the akelarre, and Barrenechea was also accused of having been "queen" of the akelarre, preceding Maria de Arburu. Barrenechea's first husband and third daughter were the only ones not accused of being witches. In her recorded confessions, Barrenechea apparently admitted to being "queen of the coven", of cannibalising dismembered children and exhumed bodies, and of having a love affair with the devil. She also confessed becoming so jealous of another woman, Marijuán de Odia, for the devil's affections that she and the devil poisoned Odia, who died three days later, with toad skin.

Besides confessions, there were many accusations against Barrenechea by children from when Barrenechea lived in Arraioz, claiming that she enticed them to the devil and tried to abduct them, with many public confrontations between the parents and Barrenechea. A passer-by saw that Barrenechea could not speak, but could breathe; bystanders encouraged Barrenechea to commit herself to God, and then she died. Children who witnessed her death said the goat-devil appeared beside her at the moment she died. In 1611, the royal council of the Inquisition absolved everyone tried of witchcraft at Logroño, She was portrayed by Carmen Maura in the 2013 film Witching & Bitching, a horror-comedy that depicts Barrenechea "reveling in demonic-lubricious libertarian rituals"; Azurmendi has been particularly critical of this portrayal.
