Tiny symbols engraved into ancient Roman drinkware may be more than merely decorative accents. The talent of ancient Rome’s artisans is displayed across the empire’s vast archaeological remains, such as its architecture, mosaics, and sculptures. Also known as a cage cup or reticulated cup, these vessels rose to popularity during the 4th century CE, and are considered apex examples of Roman glassworking. But after examining the piece firsthand in 2023, Washington State University art expert Hallie Meredith set out to compare it with other examples of Roman cage cups. Additional analysis of tool markings as well as unfinished pieces and inscriptions revealed each cage cup wasn’t made by a single artisan.
