The tegulae sulphuris: the marks of the Romans

The tegulae sulphuris are fundamental archaeological finds for understanding and studying the production activities and commercial relations that took place in Agrigentum.
They are clay tablets with inscriptions from right to left that showed the name of the workshop that produced them or who controlled their trade, to indicate their origin, just as happens today with the markings that we find on everyday objects.

tegulae sulfuris
The tegulae sulfuris were small slabs of clay used by the ancient Romans to imprint the name of the producer on the containers of molten sulfur loaves. They were presented with a rectangular shape of various dimensions, and all had high relief inscriptions from right to left, so that, on the molten sulfur, the name of the factory of origin remained engraved/engraved, readable from left to right as a normal text.
