The Romans considered the cockerel a messenger to the god Mercury, and the rooster was often depicted at the feet of the god. In Britain's Roman Cirencester, a rare and beautiful example of the cockerel was found in the grave of a child. Cotswold Archaeology features an in-depth look at the artifact on their website.

From the website:
The Cirencester cockerel is the only example to have survived with its openwork tail and the only one from Britain from a grave. When first made it would have been extremely colourful, the metal bright, and the wings, breast, eyes and tail with a pattern of red, blue and yellow enamels.
