The first men ever to have a public statue made of them—men who were not kings—were these two: Harmodius and Aristogeiton.
They tried to kill a dictator (then called a tyrant: a man who had taken power by force) and were afterwards venerated as freedom fighters—tyrannicides—by the Athenian people.
The original group-statue, by a sculptor named Antenor, was made of bronze and was set up in about 500BC on a hill across from the marketplace.
It stood there for thirty years. Then the Persians captured Athens and carried it off to their capital city as a war trophy.
As soon as the Persians left, the Athenians ordered a copy of the looted Tyrannicides statue and put it back on the hill.
Finally, two hundred years later, Alexander the Great recovered the original one from the Persian palace in Susa and had it sent back to Athens. For a long time there were two of the statues (four figures) side by side on the Areopagus hill.
They have long since disappeared; all we have are Roman copies like the one above.
