From the article:
"The dramatic discovery is a beautifully crafted miniature bronze figure of the Roman goddess Ceres which is thought to be a mount from a larger piece of furniture. Ceres was the goddess of agriculture, grain and fertility which is a highly appropriate goddess for Arbeia because it was a supply base where thousands of tons of grain were stored in granaries to feed the army stationed along Hadrian’s Wall. This is the second goddess that the WallQuest project has found at Arbeia in two years. In 2014, a local volunteer found a carved stone head of a protective goddess, or tutela.
