East meets West on the two sides of the silver tetradrachm shown here, minted in the Bactrian city of Panjhir around 145 B.C. The obverse is inscribed with Greek writing and a helmeted bust of Menander, a Hellenistic Bactrian king who converted to Buddhism in the mid-second century B.C. The coin’s reverse is written in the local Kharosthi script—which uses an alphabet derived from Aramaic—and depicts Athena, the Greek goddess of wisdom, hurling a thunderbolt.
