Sogdian

The Sogdian script developed from the Aramaic and was first used
during the 4th century AD. The earliest form of the script, shown below,
was used to write letters and for inscriptions. A cursive version of
the script was used in secular documents, royal proclamations, and
Buddhist and Manichaen manuscripts. The Sogdian script largely fell
out of use during the 10th century, though was used to some extent
until the 13th century.

Sogdian is an extinct member of the eastern branch of Middle Iranian
languages once spoken in Sogdiana, a region that includes parts of
China (Xinjiang), Uzbekistan, Tajikistan, Pakistan. Yaqnabi, a language
spoken in Tajikistan is thought to be a modern descentant of Sogdian.
