Serpent Column (also known as the Serpentine Column, Delphi Tripod or the Plataean Tripod) is an ancient column at the Hippodrome (known as Atmeydany "Horse Square" in the Ottoman period)It is an ancient Greek sacrificial tripod, originally located in Delphi and later relocated to Constantinople (modern Istanbul) by Constantine I in 324. The serpent heads of the 8-meter high column remained until the end of the 17th century. One of the missing heads was later found and put on display at the Istanbul Archaeology Museums.The Serpentine Column has one of the longest literary histories of any object surviving from Greek and Roman antiquity, and it s provenance is not in doubt. It is at least 2486 years old. It was the offering, or trophy, less its original gold tripod, which was dedicated to Apollo at Delphi, after the defeat of the Persian army in the Battle of Plataea in August, 479 BC by those Greek City States, who were in alliance against the Persian invasion of mainland Greece, in the spring of 480 BC – the Persian War. Among the writers, who attest to the column in the ancient literature are Herodotus, Thucydides, Demosthenes, Diodorus Siculus, Pausanias the traveller, Cornelius Nepos and Plutarch.The removal of the column by the Emperor Constantine to his new capital, Constantinople, is attested to by Edward Gibbon, citing the Byzantine historians, Zosimus, Eusebius, Socrates, and Sozomenus in support.
