Of these Targum Neofiti I is by far the largest. It consist of 450 folios covering all books of the Pentateuch, with only a few damaged verses. The history of the manuscript begins 1587 when the censor Andrea de Monte (d. 1587) bequeathed it to Ugo Boncompagni—which presents an oddity, since Boncompagni, better known as Pope Gregory XIII, died in 1585. The route of transmission may instead be by a certain "Giovan Paolo Eustachio romano neophito." Before this de Monte had censored it by deleting most references to idolatry. In 1602 Boncompagni's estate gave it to the College of the Neophytes, a college for converts from Judaism and Islam, until 1886, when the Holy See bought it along with other manuscripts when the Collegium closed (which is the reason for the manuscripts name and its designation). Unfortunately, it was then mistitled as a manuscript of Targum Onkelos until 1949, when Alejandro Díez Macho noticed that it differed significantly from Targum Onkelos. It was translated and published during 1968–79, and has since been considered the most important of the Palestinian Targumim, as it is by far the most complete and, apparently, the earliest as well.
