The debate over whether the statue represents Poseidon or Zeus hinges on the lost attribute held in the figure's right hand. As Caroline Houser writes, "Sometimes the Artemision protector is called 'Poseidon'. Those who would do so have been known to argue that the image must be that of the great sea god since the statue was found in the Mediterranean. But like other statues of totally different subjects, this one went into the sea simply because it was on board a ship that sank. Others cite the example of the Poseidonia coins, overlooking the much weightier evidence presented by the numerous surviving statuettes of Zeus launching his thunderbolt in a pose matching that of the Artemision figure."[5]
A major additional problem with that hypothesis is that a trident would obscure the face, especially from the profile view, which most scholars (even those who have supported an identification as Poseidon) have held to be the most, or even the only, important view. Iconographic parallels with coins and vase painting from the same time period show that this obscuring pose is extremely unlikely. However, the trident may have been unusually short, avoiding the problem. On the other hand, the statue is essentially a larger version of an extensive series of smaller solid bronze figurines extending back into the late 7th century, all of which strike the same pose and represent Zeus.[6] On the basis of this and other iconographic parallels with vase-painting,[7] most scholars presently think it is a Zeus. However, opinion remains divided.
The god is caught at the moment of pause in the full potentiality of his coming movement, described by Carol Mattusch: "the figure has the potential for violence, is concentrating, poised to throw, but the action is just beginning, and we are left to contemplate the coming demonstration of strength."[8] It is an original work of great strength in the Severe style that preceded the fifth-century classical style, dated to ca. 460 BCE. A comparison can be made with the Charioteer of Delphi, a roughly contemporaneous bronze.
