シリア文字
The Sogdian alphabet was originally used for the Sogdian language, a language in the Iranian family used by the people of Sogdia. The alphabet is derived from Syriac, a descendant script of the Aramaic alphabet. The Sogdian alphabet is one of three scripts used to write the Sogdian language, the others being the Manichaean alphabet and the Syriac alphabet. It was used throughout Central Asia, from the edge of Iran in the west, to China in the east, from approximately 100–1200 A.D.
