The earliest of Phidias' works were dedications in memory of Marathon, celebrating the Greek victory. His first commission was a group of national heroes with Miltiades as a central figure. At Delphi he created a great group in bronze including the figures of Greek gods Apollo and Athena, several Attic heroes, and General Miltiades the Younger. On the Acropolis of Athens, Phidias constructed a colossal bronze statue of Athena, the "Athena Promachos", which was visible far out at sea. Athena was the goddess of wisdom and warriors and the protector of Athens. At Pellene in Achaea, and at Plataea, Phidias made two other statues of Athena, as well as a statue of the goddess Aphrodite in ivory and gold for the people of Elis.
