Linguistic features of the (Galilean) Aramaic text, including its many Greek loan words, are one of the stronger arguments in support of an earlier dating. More recently Allegra Iafrate (2015) argued for a date in the 10th century due to the fact that Targum Sheni shows dependency on and shares striking similarities with De Ceremoniis, a work which itself was composed in the middle of the 10th century in the Byzantine Empire.
