A copper-alloy seal-box lid of the Roman period.

The lid is piriform, with an incomplete hinge lug at the larger end. It is decorated with a separately moulded phallus, secured with a single rivet. The end of the phallus is flattened with a circular slight depression and deeper central dot. This area would very probably have been enamelled, but no traces survive. The surface of the cover is tinned.
