Carben Victor, a convert, living at Cologne between 1442 and 1515, was the author of the following controversial works: (1). "Opus Aureum ac Novum in quo Omnes Judaeorum Errores Manifestatur." (2). "Propugnaculum Fidei Christianæ, Instar Dialogi inter Christianum et Judæum in quo quod Jesus verus Messias, verus Deus et Homo, Totius que Humani Generis Salvator."
Canta Joshua Dei, according to Steinschneider, belonged to the family Cantarini (מהחזנים), and according to Wolf, B. II. i. 131, he was a convert to Christianity. He, together with Baptista Vittorio Eliano, denounced the Talmud as containing blasphemies against the Christian faith, in 1559, and the result was the burning of Hebrew books, and his own assassination in the streets of Cremona.
Carthagena don Alfonso, son of Paul of Burgos, died at Burgos in 1456. He was baptized together with his father, brother and sister, in 1391, and became Archdeacon of Compostella, and then succeeded his father in the See of Burgos. The writers in the "Jewish Encyclopædia" contradict each other in ascribing the succession at Burgos to both him and his brother Alonzo, which cannot be unless one brother succeeded another. In 1431 he was the representative of Castile at the Council of Basel. Pope Pius II., in his memoirs, called him "An ornament to the prelacy." Pope Eugenius IV., hearing that the Bishop of Burgos was about to visit Rome, declared in full conclave, that "in presence of such a man he felt ashamed to be seated in St. Peter's chair." Among Carthagena's writings, on history, morals, and other subjects, there is a commentary on the twenty-sixth Psalm, "Correctus Ludovicius."
Cohen Todoros, a native of France, lived at Florence in the sixteenth century. After he embraced Christianity, at the age of fifty, at Geneva, he wrote a book entitled "Maroth Elohim, Liber Visorum Divinum," in which he relates the history of his conversion, and quotes passages from the Bible and Kabbalistic works in favour of Christianity. The work, published in Paris in 1553, was translated into Latin by Angelo Caruni (Florence, 1554). It is inserted in Johannes Buxtorf's "Synagoga Judaica."

Cardinal Ximenes de Cisneros commissioned him to translate the Bible into Latin. This translation is contained in the "Complutensian Polyglot" (1541-17). He also wrote "Additiones ad Librum Nicolai Lirani de Differentiis Translationem (Verborum)," which has not been printed.
Crescenzi Alexander lived at Rome in the seventeenth century. In 1666 he translated from the Spanish into Italian Antony Colmenarde Ludesina's treatise on "Chocolate." Mandosius speaks of him as a mathematician who became celebrated on account of his report, which he edited with mathematical notes, on the eruption of Vesuvius in 1660.
Christiani Pablo, a convert of the thirteenth century. After his baptism he became a member of the Order of the Dominicans. He is notorious as an over-zealous missionary, who cherished the Boanergian spirit more than the spirit of Christ towards his brethren, and he is only mentioned here on account of the famous controversy he held at the palace of King James with the great Rabbi Nahmonides, when he tried to prove from the Talmud the truth of Christianity, and Rabbi Nahmonides declared that he did not believe in the Haggadic stories of the Talmud.
Compiegne de Weil, Ludwig, lived at Paris, and later at Metz, in the second half of the seventeenth century. He was a descendant of Rabbi Jacob Weil, of Nuremberg. After embracing Christianity he studied theology at the Sorbonne. He translated several parts of Maimonides' "Yad ha Hazakah."
