Modern scholarly consensus is that the Eastern Iranian language ancestral to the Pamir languages in Central Asia and the medieval Saka language of Xinjiang, was one of the Scythian languages. Evidence of the Middle Iranian "Scytho-Khotanese" language survives in Northwest China, where Khotanese-Saka-language documents, ranging from medical texts to Buddhist texts, have been found primarily in Khotan and Tumshuq (northeast of Kashgar). They largely predate the Islamization of Xinjiang under the Turkic-speaking Kara-Khanid Khanate. Similar documents, the Dunhuang manuscripts, were discovered written in the Khotanese Saka language and date mostly from the tenth century.
