the statue was set up at delphi to commemorate the victory of the tyrant polyzalus of gela in sicily and his chariot in the pythian games of 470 bc, which were held at delphi in honor of pythean apollo. it has also been suggested that the complex was actually commemorating the victory of polyzalos' brother, hieron, at the pythian games of 470 bc in analogy to his ex voto after his victory at the olympic games. it was originally part of a larger group of statuary, including the chariot, at least four horses and possibly two grooms. some fragments of the horses were found with the statue. the masterpiece has been associated with the sculptor pythagoras of samos who lived and worked in sicily, as well as with the sculptor calamis. the sicilian cities were very wealthy compared with most of the cities of mainland greece and their rulers could afford the most magnificent offerings to the gods, also the best horses and drivers. it is unlikely, however, the statue itself comes from sicily. the name of the sculptor is unknown, but for stylistic reasons it is believed that the statue was cast in athens. it has certain similarities of detail to the statue known as the piraeus apollo, which is known to be of athenian origin.
