Bible translations into Sogdian

Portions of the Bible were translated into the Sogdian language in the 9th and 10th centuries. All surviving manuscripts are incomplete Christian liturgical texts (psalters and lectionaries), intended for reading on Sundays and holy days. It is unknown if a whole translation of any single book of the Bible was made, although the text known as C13 may be a fragment of a complete "Gospel of Matthew". All but one text are written in Syriac script; only a few pages of the "Book of Psalms" written in Sogdian script are extant.
None of the surviving Sogdian texts was translated from the original Hebrew or Greek. All but one are derived from Syriac translations, mostly from the "Peshitta" but with some readings in C5 that could be from the "Vetus Syra" or the "Diatessaron". One, a text of Psalm 33 under a Greek heading, was translated from the Septuagint. A number of Sogdian translations of non-Biblical works, both Christian and Manichaean, contain Biblical quotations, but these were translated along with the works in which they are found.
All surviving Sogdian Biblical texts were found in the ruins of the monastery of Bulayïq, near Turpan, which was affiliated with the East Syriac Church of the East. The Psalm 33 fragment translated from Greek probably originally belonged to the Melkite community of Tashkent in Sogdia proper. Biblical texts in Syriac, Middle Persian and New Persian have been found at the same site. It appears that Sogdian, the local vernacular, gradually displaced Middle Persian, the vernacular of the early missionaries, and was in turn displaced by New Persian as that language spread in Central Asia. The first language of a majority of the monastic community of Bulayïq, however, was Old Uyghur towards the end.
The Bible has not been translated into the sole surviving descendant of Sogdian, the Yaghnobi (Neo-Sogdian) language.
