Head of either the god Serapis or Jupiter as suggested by the rays of the crown. The god has a paternal expression which would fit either Serapis or Jupiter. The head is unbroken and looks in a pristine condition to be ancient. The face has a particularly granular face that may have been intentional to make it look ancient. There are two drilling holes by the nose that are not common in ancient pieces and may have been used for taking measurements.
Blundell's 'Account' refers to the head as being discovered in ruins on the Via Appia in Rome. He appreciated it for its dignity and great majesty and identified it because of the golden rays of lights on its head.
