The macellum was Aizanoi's market building, and its fame comes from inscriptions connected with Emperor Diocletian's Price Edict. That edict tried to fix maximum prices across the Roman Empire, a wonderfully human reminder that inflation and official frustration are not modern inventions.
The structure is not as dramatic as the temple, but it adds texture to the visit. Aizanoi was not only sacred and ceremonial; it was also a working city with trade, taxes, and everyday bargains.
