The most prominent among the new Conversos was Selemoh Ha-Levi, a rabbi who had been the most intrepid defender of the faith and rights of his race. On the eve of the massacres, which perhaps he foresaw, and influenced by an opportune vision of the Virgin, in 1390, he professed conversion, taking the name of Pablo de Santa María, and was followed by his two brothers and five sons, founding a family of commanding influence. After a course in the University of Paris he entered the Church, rising to the see of Cartagena and then to that of Burgos, which he transmitted to his son Alfonso. At the Córtes of Toledo, in 1406, he so impressed Henry III that he was appointed tutor and governor of the Infante Juan II, Mayor of Castile and a member of the Royal Council. When, in the course of the same year, the king died he named Pablo among those who were to have the conduct and education of Juan during his minority; when the regent, Fernando of Antequera, left Castile to assume the crown of Aragon, he appointed Pablo to replace him, and the pope honored him with the position of legate _a latere_. In 1432, in his eighty-first year, he wrote his _Scrutinium Scripturarum_ against his former co-religionists. It is more moderate than is customary in these controversial writings and seems to have been composed rather as a justification of his own course.[335] Another prominent Converso was the Rabbi Jehoshua Ha-Lorqui, who took the name of Gerónimo de Santafé and founded a family almost as powerful as the Santa Marías. He too showed his zeal in the book named _Hebræomastix_, in which he exaggerated the errors of the Jews in the manner best adapted to excite the execration of Christians. Another leading Converso family was that of the Caballerías, of which eight brothers were baptized and one of them, Bonafos, who called himself Micer Pedro de la Caballería, wrote, in 1464, the _Celo de Cristo contra los Judíos_ in which he treated them with customary obloquy as the synagogue of Satan and argues that the hope of Christianity lies in their ruin.[336] In thus stimulating the spirit of persecuting fanaticism we shall see how these men sowed the wind and reaped the whirlwind.
