Witches' Sabbath (Goya, 1798) feature of Romanticism, and is to be found for example in Weber's opera "Der Freischütz". However, in a Spanish context, Goya's paintings have been seen as a protest against those who upheld and enforced the values of the Spanish Inquisition, which had been active in Witch hunting during the seventeenth-century Basque witch trials. The later "Witches Sabbath" was painted as a bitter struggle raged between liberals and those in favour of a church and a royalist-lead state, which culminated in the so-called Ominous Decade (1823-1833). Both paintings can be seen as an attack on the superstitious beliefs rife in Spain

In connection with the medieval beliefs in the evil power of witches and in the malevolence of Jews and Judaizing heretics (both being Sabbathkeepers), satanic gatherings of witches were by outsiders called "sabbats", "synagogues", or "convents". Local variations of the name given to witches' gatherings were frequent. Perhaps the earliest work that mentions a something like a gathering that might be interpreted, from the Christian point of view, as witches sabbath is"Canon Episcopi" (906) and later included in Burchard of Worms's collection in the 11th
