The Athena Promachos (Ἀθηνᾶ Πρόμαχος "Athena who fights in the front line") was a colossal bronze statue of Athena sculpted by Pheidias, which stood between the Propylaea and the Parthenon on the Acropolis of Athens. Athena was the tutelary deity of Athens and the goddess of wisdom and warriors. Pheidias also sculpted two other figures of Athena on the Acropolis, the huge gold and ivory ("chryselephantine") cult image of Athena Parthenos in the Parthenon and the Lemnian Athena.
The designation Athena Promachos is not attested before a dedicatory inscription of the early fourth century CE;Pausanias (1.28.2) referred to it as "the great bronze Athena" on the Acropolis.
The Athena Promachos was one of the earliest recorded works by Pheidias. It was erected during the Classical period of Ancient Greek culture, approximately 456 BCE. It was made with the Persian spoils of the Battle of Marathon, won some years earlier. Parts of the marble base remain; according to the preserved inscription, it measured about 10 m (30 ft) high. It showed Athena standing with a spear alongside, her shield resting upright against her leg, and her right arm extended, bearing a winged figure in that hand. The statue was so large it is said that the tip of the spear and her helmet crest were visible at sea, off Cape Sounion.
Surviving accounts for the creation process for the sculpture cover nine years, but the dates are not identifiable, because the names of officials are missing. The sculpture may have commemorated Kimon's defeat of the Persians at the Eurymedon in 467 or the peace of Kallias in approximately 450 or 449.
