The College maintained the Dominican tradition of textual and linguistic activities as part of the Order's missionary dimension. Like Moerbeke's translations of Aristotle in the 1260s and the "editio piana" of 1570 (see above), editorial and translation projects were undertaken by the college's professors, the most notable of which would be the "leonine edition" of Aquinas' works (see below). Vincenzo Candido (1573-1654) presided over the translation of the Bible into Arabic. Candido had entered the Order at the convent of Santa Maria sopra Minerva completing there his novitiate and studies and becoming a doctor of theology, and later rector of the College in 1630. Candido also was part of the commission that concemned Jansenism. His own "Disquisitionibus moralibus" (1643) was later accused of laxims. Giuseppe Ciante (d. 1670), a leading Hebrew expert of his day and author of works such as the "De sanctissima trinitate ex antiquorum Hebraeorum testimonijs euidenter comprobata" (1667) and "De Sanctissima incarnatione clarissimis Hebraeorum doctrinis...defensa" (1667), completed his studies at the college was professor of theology and philosophy there before 1640. "In 1640 Ciantes was appointed by Pope Urban VIII to the mission of preaching to the Jews of Rome ("Predicatore degli Ebrei") in order to promote their conversion." In the mid-1650s Ciantes wrote a "monumental bilingual edition of the first three Parts of Thomas Aquinas' "Summa contra Gentiles", which includes the original Latin text and a Hebrew translation prepared by Ciantes, assisted by Jewish apostates, the "Summa divi Thomae Aquinatis ordinis praedicatorum Contra Gentiles quam Hebraicè eloquitur…". Until the present this remains the only significant translation of a major Latin scholastic work in modern Hebrew."
