This is a 14th-century translation of the entire book of Jonah into Judeo-Greek or Yevanic, the traditional language of the Romaniote community of Byzantium. To quote the Judeo-Greek expert Julia G. Krivoruchko, it “exhibits a fusion of contemporary vernacular language with archaic elements” and “favors an extremely literal translation style.” This translation was first published in Greek transcription by the Dutch hellenist Dirk Christiaan Hesseling, who misdated it to the 12th-century based on a mixup between the Seleucid and common eras. Included as part of a Romaniote maḥzor (Bodleian Library MS. Oppenheim Add. 8° 19), this translation was almost certainly in use as a targum for the reading of Jonah as the Yom Kippur minḥa haftarah. In the original manuscript the majority of verses are preceded with a few words of the Hebrew, a common practice for written targumim. . . .
