Why do some scholars identify the bronze head from Nineveh as Sargon of Akkad?

Scholars often identify the life-size bronze head found at Nineveh as Sargon of Akkad because of its historical and cultural context within the city.

The identification is supported by the following points:

• Dynastic Significance: Inscriptions confirm that Sargon’s second son, Manishtusu, built the temple of E-Mashmash at Nineveh, explicitly identifying himself as the "son of Sargon." It is considered highly probable that a statue of the dynasty's founder would have been placed in such a significant location.1
• Artistic Style: The head features a monarch wearing the traditional wig-helmet of early Sumerian rulers, a style associated with the founder of the Akkadian Empire.21

While some researchers suggest the head could represent Sargon's grandson, Naram-Sin, due to the piece's sophisticated casting and modeling techniques, many experts prefer the attribution to Sargon. This preference is based on the observation that metalwork in Mesopotamia advanced in style more rapidly than stone sculpture during that era, making the earlier date consistent with the high quality of the bronze work.1
