The bowl to the right is called the Staffordshire Moorlands cup and it was discovered in 2004 by experienced metal detectors out for a walk.
The bowl has the names of the first 5 forts on Hadrian's Wall engraved along the top outside rim, and originally had a handle and might have been used as a type of skillet. It dates to the 2nd century.
It has elaborate Celtic-style curvilinear design and possesses much of its original decoration which was done in vivid turquoise, blue, red, yellow and purple enamel.
In the photo below you can see the name "DRACO" inscribed on the top left. It is uncertain if Draco was the owner of the bowl or the person who manufactured it.
The photo below is of a copy of the Rudge cup, found at the bottom of a well at the site of a Roman villa in Wiltshire, England. It shows a representation of Hadrian's Wall with its turrets and milecastles. The cup dates to the first half of the second century and also lists forts on the Wall.
It is believed that these bowls are military souvenirs of the time, much as we would go on a trip and buy a coffee cup or a set of salt and pepper shakers with "Niagara Falls" or "Las Vegas" emblazoned on it. Probably only high-ranking Roman officers could afford to purchase these.
I visited Hadrian's Wall in northern England in 2008 while I was writing Eleri's Tale. Fascinating country!
