seconda metà IV sec. d.C.
The bronze aquamarine pan features an engraved decoration with the head of the ocean in the central round surrounded by marine scenes. The scenes represent a sailor on a sailboat carrying amphorae, a fisherman with a rod, two fishermen with nets collected in a rowboat and a standing fisherman with a rod and fish. The entire field is thickly filled with depictions of animals and sea birds. The aquamarine pan is an accessory of the banquet service: it was in fact used for washing hands, as documented by the depiction on a silver plate of the late 4th century by Cesena, who represents a servant in the act of pouring water from a jug inside the pan, while the guest rinses his hand. This type of bronze pan was produced until the seventh century. The specimen of the Crypta Balbi represents one of the highest achievements of late antiquity toreutics, probably created by an atelier active in Rome in the advanced IV century which elaborated with a particular style models of the previous century. For this reason, the dating of the aquamarine pan can take place in the second half of the fourth century.
