A bronze column in the shape of intertwined snakes (the Serpent column) was created from melted-down Persian weapons, and was erected at Delphi. It commemorated all the Greek city-states that had participated in the battle, listing them on the column, and thus confirming some of Herodotus's claims. Most of it still survives in the Hippodrome of Constantinople (present-day Istanbul), where it was carried by Constantine the Great during the founding of his city on the Greek colony of Byzantium.
