Firmalampen, or "factory lamps," were among the first mass-produced products during Roman times and were imported throughout the Empire. There were even recognizable brand names such as Strobili, Communis, Phoetaspi, Eucarpi and Fortis. "It was indeed a commercial success. Fortis gained such a name for its lamps that its stamp was copied and reproduced throughout the empire. It was one of the earliest examples of pirated brands," said Donato Labate, the archaeologist in charge of the dig.
