What it is

A cursive alphabet derived from Aramaic used to write Sogdian, the lingua franca of Silk Road merchants. The Ancient Letters, found in a Great Wall tower at Dunhuang, are its first great dated evidence.

The Ancient Letters (Aurel Stein, 1907) are dated to c. 313 AD; older Sogdian inscriptions exist but are scarce, so the exact origin of the script is uncertain.

What it led to

  • the Old Uyghur script, from which Mongolian derives
  • commercial, Buddhist, Manichaean and Christian documents in Sogdian
  • the role of the Sogdians as intermediaries between China, India and Persia
