After the Classical period, references to Antandrus become scarce in surviving sources. The next reference to events at Antandrus comes several centuries later c. 200 BC, when Antandrus was on the route of Delphic "thearodokoi", and in the 2nd century BC an inscription from Antandrus tells us that the city sent judges to Peltai in Phrygia to arbitrate a dispute. From c. 440 - c. 284 BC, Antandrus had minted its own coinage; this began again in the reign of the Emperor Titus (AD 79-81) and continued until the reign of Elagabalus (AD 218-222). In the Byzantine period Antandrus was an episcopal see in the metropolis of Ephesus.
