Archaeologists have found a major pottery workshop site which specialized in the mass production of 'name-brand' lamps for the ancient Roman world. According to Discovery.com, a dump near the site contained items marked with the Strobili, Communis, Phoetaspi, Eucarpi and Fortis 'labels'. The brand names have been found in all parts of the Roman Empire and Fortis was especially 'trendy' (their word) right into the second century A.D.. In regards to the latter, it has long been suspected that Fortis was based in Mutina/Modena, and now we have strong evidence of such.

Donato Labate (the archaeologist in charge of the dig) said (inter alia):

"We found a large ancient Roman dumping filled with pottery scraps. There were vases, bottles, bricks, but most of all, hundreds of oil lamps, each bearing their maker's name."

"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."

"We know now for sure that Fortis came from Mutina. The city was a major pottery center, a cluster of pottery workshops, as the variety of brand names on the newly discovered items testifies."


Just to give you an idea of how far afield a Fortis lamp might go, back in 2001 one was found at Carmarthenshire (Wales); photo and report at the BBC.
