Æ20 - Caracalla ΘΥΑΤΕΙΡΗΝΩΝ

Thyatira, a Lydian city whose prosperity rested almost entirely on its dyeing and textile guilds, was among the most prolific issuers of civic bronze in the Pergamene conventus — a Roman judicial district that grouped smaller cities under Pergamum's administrative umbrella. The city struck continuously throughout Caracalla's reign, from his co-emperorship under Septimius Severus through his sole rule after his brother Geta's murder in 211.

The reference V.2#77469 places this within the Vogt corpus of Lydian civic bronzes, a cataloguing system that remains the primary scholarly tool for distinguishing the city's prolific and often difficult-to-differentiate issues.
