Psalms, Proverbs, and Job are generally treated as a unit, as are the targumim of the five scrolls (Esther has a longer "Second Targum" as well.) The targum of Chronicles is quite late, possibly medieval, and is attributed to a Rabbi Joseph. Other Targumim on the Torah There are also a variety of western targumim on the Torah, each of which was traditionally called Targum Yerushalmi ("Jerusalem Targum"), and written in Western Aramaic. An important one of these was mistakenly labeled "Targum Jonathan" in later printed versions (though all medieval authorities refer to it by its correct name). The error crept in because of an abbreviation: the printer interpreted the abbreviation T Y (ת"י) to stand for Targum Yonathan (תרגום יונתן) instead of the correct Targum Yerushalmi (תרגום ירושלמי). Scholars refer to this targum as Targum Pseudo-Jonathan. To attribute this targum to Jonathan ben Uzziel flatly contradicts the talmudic tradition (Megillah 3a), which quite clearly attributes the targum to Nevi'im alone to him, while stating that there is no official targum to Ketuvim. In the same printed versions, a similar fragment targum is correctly labeled as Targum Yerushalmi. The Western Targumim on the Torah, or Palestinian Targumim as they are also called, consist of three manuscript groups: Targum Neofiti I, Fragment Targums, and Cairo Geniza Fragment Targums. 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
