Kharosthi script was used for many Gandharan Buddhist manuscripts linked to Silk Road exchange.
Kharosthi was an ancient script used mainly in the northwestern Indian subcontinent, especially Gandhara. It was written from right to left and is generally understood to have developed under influence from the Aramaic writing tradition used in the Achaemenid administrative world.
The script recorded Gandhari, an Indo-Aryan language. Buddhist texts written in Kharosthi are among the oldest surviving Buddhist manuscripts, and their discovery has helped scholars study how Buddhist ideas and texts moved through Central Asia.
Kharosthi eventually disappeared, probably by about the 3rd or 4th century CE. Brahmi was a different and more widely spreading South Asian script, while Sogdian script was associated with an Iranian language and merchant communities farther west and north.
