The Athena Pallas Giustiniani (Or Giustiniani Minerva) is an Antonine Roman marble copy of a Greek sculpture of the Pallas Athena, of the late fifth-early fourth century BC.
The sculpture was probably a cult image rather than a decorative cultural trophy. The serpent at Athena's right foot recalls the archaic myth of Ericthonius in his serpent form. The forearms are restorations, as are the spear and the sphinx upon the goddess's Corinthian helmet.
