Syriac is the language of ancient Syria and one of the dialects of Aramaic, which was an official language of the Persian Empire. It was spoken in northern Mesopotamia and around ancient Antioch. In the second or third century C.E., as a written language, Syriac came into wide use. Within this Western dialect of Aramaic, many important early Christian texts are preserved, and which is still used by Syrian Christians as a liturgical language.
