This head shows a great resemblance to a head on a coin found near Olympia. From the inscription on the coin we know that the head is of the cult statue of Zeus in his temple at Olympia by Pheidias, which was lost in antiquity. Combined with literary evidence, this head gives us a good idea of what the cult statue looked like
