Scripts
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."
