Thus all wise-women and charlatans became subject to the jurisdiction of the Inquisition, and no richer field for the folklorist can be found than in their numerous trials, where all the details of their petty devices and spells and charms are reported at length. There was the corresponding duty imposed on it to exterminate all popular superstitions throughout the land, and possibly it might have had a measure of success in this if it could have treated these practitioners as impostors. Unfortunately its jurisdiction over them was based on the reality of their exercising demonic powers, and their persecution only tended to confirm popular belief in the efficacy of their ministrations, while the public reading of their sentences _con meritos_ spread abroad the knowledge of their powers and formulas. If aught was lacking to strengthen belief in sorcery and divination it was furnished, in 1585, by Sixtus V, in his solemn bull _Coeli et Terræ_. In this he denounced astrology and all other species of divination, all magic incantations, the invocation and consultation of demons, the abuse of the sacraments, the pretended imprisonment of demons in rings, mirrors and vials, the obtaining of responses from demoniacs or lymphatic or fanatic women; he commanded all prelates and bishops and inquisitors diligently to prosecute and punish all who were guilty of these illicit divinations, sorceries, superstitions, magic, incantations and other detestable wickedness, even though hitherto they had no faculty to do so, and the rules of the Tridentine Index, prohibiting all works on divination and magic were to be strictly enforced.[413] The Spanish Inquisition, as we have seen, had long before exercised all the faculties conferred by the bull, and it is difficult to understand why, in 1595, it obtained for the first time, in the commission issued to Inquisitor-general Manrique de Lara, a clause covering all who practised these diabolical arts, and all who believed and employed them--a clause retained in all subsequent commissions.[414] The Inquisition, in fact, had not welcomed the bull, possibly in fear of claims based on it of cumulative episcopal jurisdiction. It did not allow it to be published in Spain until 1612 when, for some reason, a Romance version was printed and sent to all the tribunals with orders for its publication and enforcement, leading subsequent writers to attribute to it the cognizance of these matters by the Inquisition.[415] [Sidenote: _EXCLUSIVE JURISDICTION_]
