Zhang-Zhung (Tibetan: ཞང་ཞུང, Wylie: zhang zhung) is an extinct Tibeto-Burman language that was spoken in what is now western Tibet. The term 'Zhang-zhung language' has been used to refer to two different entities. One of these occurs occasionally in the scriptures of the Bön religion. The other, 'Old Zhang-zhung', appears in a small number of documents preserved in Dunhuang. The language of these texts was identified as 'Zhang-zhung' by F. W. Thomas and this identification has been accepted by Takeuchi Tsuguhito (武内紹人). However, Dan Martin questions the wisdom of identifying these as variants of the same language.
'A Cavern of Treasures' (mdzod phug)
'A Cavern of Treasures' (Tibetan: མཛོད་ཕུག, Wylie: mdzod phug) is a terma uncovered by 'Shenchen Luga' (Tibetan: གཤེན་ཆེན་ཀླུ་དགའ, Wylie: gshen chen klu dga') in the early eleventh century. Martin (n.d.: p. 21) identifies the importance of this scripture for studies of the Zhang-zhung language:
"For students of Tibetan culture in general, the mDzod phug is one of the most intriguing of all Bön scriptures, since it is the only lengthy bilingual work in Zhang-zhung and Tibetan (some of the shorter but still significant sources for Zhang-zhung are signalled in Orofino 1990)."
Bradley (2002) says Zhangzhung "is now agreed to have been a Kanauri or West Himalayish language." Guillaume Jacques (2009) rebuts earlier hypotheses that Zhangzhung might have originated in eastern (rather than western) Tibet by having determined it to be a non-Qiangic language.
The Zhang Zhung language is claimed to have multiple different scripts. However, these scripts appear to have little existence outside of calligraphy manuals. One extant document, a seal originally held at Tsurpu monastery, is claimed to be written in such a script. In the words of McKay (2003: p. 447):
"There is also a Zhang-zhung alphabet, but despite its rather unusual appearance to anyone who is unfamiliar with the Indo-Tibetan ornate style of lettering known as lan-tsha, one observes that it is modeled letter by letter upon Thon-mi Sambhota's alphabet of thirty letters."
