Naples National Archaeological Museum
Its main example is a 63 cm high Roman marble copy of the 1st century AD of a Greek original of the second half of the 5th century BC, now in the Naples National Archaeological Museum. It was part of a colossal acrolithic statue, and shows the goddess with a central parting and wearing a diadem. It was named Hera by the first archaeologists to see it, due to its severe style and unsmiling expression, and they also interpreted these features as making it a Roman copy of an original by Polycleitus.
