History professor Hallie Meredith discovered hidden markings on an ancient Roman glass cup, revealing new insights into the empire's glassware culture from around the 4th to 6th centuries AD.
The abstract openwork shapes, previously considered decorative, are now believed to be the ancient equivalent of 'brand logos', identifying the workshops and artisans responsible for the intricate glassworks.
Dr Meredith's research suggests that luxurious diatreta cups were not crafted by individual glassmakers but by coordinated teams of engravers, polishers, and apprentices.
These marks indicate collective workshops rather than personal autographs, highlighting a sophisticated and collaborative production process that could span weeks or months.
The findings challenge long-standing historical debates on Roman glass vessel production, emphasising the importance of understanding the people and teams behind the craftsmanship.
