context_page_description: Lope de Barrientos, sometimes called Obispo Barrientos, was a powerful clergyman and statesman of the Crown of Castile during the 15th century, although his prominence and the influence he wielded during his lifetime is not a subject of common study in Spanish history.
  From relatively humble beginnings in Medina del Campo, where he studied grammar, he took advantage of a secular custom of Castilian monarchs to selectively promote lower class court nobility to the service of Ferdinand I of Aragon—a privilege normally reserved for those of high birth.
  Barrientos exploited every opening to climb in social rank against the backdrop of a complex political atmosphere: he became a Dominican friar; served as a professor of theology at the University of Salamanca; as the bishop of three successive cities—Segovia, Ávila, and chiefly of Cuenca
  —as royal confessor of John II of Castile; an Inquisitor; an advisor to Henry IV of Castile; and as Chancellor of Castile. In addition, he published a series of theological treatises and tracts concerning religious problems encountered in 15th-century Spain.
context_section_description: Because the majority of Lope de Barrientos' writings are of a theological bent and addressed to issues of his era, they are more the province of scholarly study today, than of general interest. The major portion of his work is addressed to the ideological modernization of the Hispanic Church. He penned a number of treatises on the Sacraments (all in Latin), a compendium of moral theology and a Book of laws with which he hoped to contribute to the enrichment of canonical law.
  Clavis Sapientiae: Barrientos' earliest extant work—a theological philosophy encyclopedia of the epoch. Although no originals survive, a hand-written copy is held by the national Library of Madrid.
  Opusculum super intellectu quorumdam verborum cuiusdam decreti contenti in volumine decretorum, ubi Gratianus, tractans de materia sacrilegii, XVII, q. III, ait: sacrilegii quoque reatum incurrit, qui iudaeis publica officia committit: A discussion of the social, religious, racial and doctrinal problem that, according to Lope de Barrientos, were provoked by Jews. For him, the most suitable solution was their segregation, and, if possible, their expulsion (which would occur just a few years later, partly at his instigation). Some manuscripts survive in good condition; a few in the hands of private parties and others in various cathedral archives.
  Index latinus ad sancti Antonini, Archiepiscopi Florentini, Summam Theologicam: Manuscript preserved in the file of the Cathedral of Segovia.
  He also wrote several, less specialized manuscripts in Spanish, but intended for an educated audience.
  Crónica del halconero (1454): A chronicle chiefly of the life of  John II of Castile, as well as of the writer, Álvar García of Santamaría.
  Contra algunos zizañadores de la nación de los convertidos del pueblo de Israel (1445–1451) ("In opposition to those who agitate against converted Israeli people"): A defense of Spanish Jewish converts. The Library of the University of Salamanca has one copy and another copy from the 17th century is in the National Library of Madrid.
  Tratado de caso e fortuna ("Treatise on Prophesies"): Written at the request of John II of Castile while Barrientos was bishop of Cuenca, it is purely scholastic and discursive, with excessive reliance on Aristotelian teachings and little original material. It was published in 1927 in Salamanca, but there are ancient copies in: the National Library of Madrid dating to 1549; another in the British Museum in London dating to the 15th century; and a last copy in the Library of the University of Salamanca.
  Tractado del dormir et despertar et del soñar et de las adevinanças et agüeros et profeçía ("Treatise on sleeping and waking; of dreaming and of divinations; of presages and prophecies"): Consists of six treatises created at the behest of John II, following his satisfaction with the Tratado de caso e fortuna, and displays a similar orthodox form. It attempts to distinguish divinely inspired dreams concerning biblical scripture and biblical figures such as Joseph, from dreams that are nothing more than dreams. It also explores the Christian theory of the prophet and the omens and riddles presented in the Bible. The British Museum of London has a number of well-preserved copies. There is one hand-written copy dating from 1559 held by the National Library of Madrid and a few more in the University of Salamanca library dating from the 15th century.
  Tractado de la divinança ("Treatise on divination"): Thought to be a manipulated summary of a book from the library of Enrique de Villena, but nonetheless considered Barrientos' most important work, it is a didactic sermon with philosophical pretensions that explores theories of philosophy which deny the possibility of divination, contrasting them with the religious sphere where many have been directly affected by divine intervention, as well as by the influence of evil spirits. In order to demonstrate that malignant spirits can influence the lives of men, he explores the Genesis story of Eve and the serpent in the Garden of Eden. He arrives at the conclusion that the "
