The bulk of the “Directorium” is little more than a compilation. It is divided into three parts. The first lays down the chief Articles of the Christian Faith; the second is a collection of the decretals, bulls, and briefs of the popes upon the subject of heretics and heresies, and the decision of the various councils held to determine matters connected with heretics and their abettors, sorcerers, excommunicates, Jews and infidels; the third part, which is Eymeric’s own contribution to the subject, deals with the manner in which trials should be conducted, and gives a detailed list of the offences that come under the jurisdiction of the Holy Office. It may be well before proceeding further to give a résumé of the grounds upon which the Inquisition instituted proceedings, as set forth in the “Directorium.” * * * * * All heretics in general are subject to the animadversions of the Holy Office; but there are, in addition, certain offenders who, whilst not exactly guilty of heresy, nevertheless render themselves justiciable by the Inquisition. These are: BLASPHEMERS who in blaspheming say that which is contrary to the Christian Faith. Thus, he who says, “The season is so bad that God Himself could not give us good weather,” sins upon a matter of faith. SORCERERS AND DIVINERS, when in their sorceries they perform that which is in the nature of heresy--such as re-baptizing infants, burning incense to a skull, etc. But if they confine their sorceries to foretelling the future by chiromancy or palmistry, by drawing the short straw, or consulting the astrolabe, they are guilty of simple sorcery, and it is for the secular courts to prosecute them. Amongst the latter are to be placed those who administer love-philtres to women. * * * * * DEVIL-WORSHIPPERS: Those who invoke devils. These are to be divided into three classes: (_a_) Those who worship the devil, sacrificing to him, prostrating themselves, singing prayers and fasting, burning incense or lighting candles in his honour. (_b_) Those who confine themselves to offering a _Dulie_ or _Hyperdulie_ cult to Satan, introducing the names of devils into the litanies. (_c_) Those who invoke the devil by tracing magic figures, placing an infant in a circle, using a sword, a bed, or a mirror, etc. In general it is easy to recognize those who have dealings with devils on account of their ferocious aspect and terrible air. The invocation in any of the three manners cited is always a heresy. But if the devil should only be asked to do things that are of his office--such as to tempt a woman to the sin of luxury--provided that this is done without adoration or prayer, but in terms of command, there are authors who hold that in such cases the person so proceeding is not guilty of heresy.
