The tyranny of the Deinomenids, under whom Syracuse had become a great power in the Greek world, was overthrown in about 466 BC and replaced by a new oligarchic constitution traditionally called the Second Democracy. This tetradrachm is from the rare first issue of this new government. While superficially similar to the Deinomenid issues of the 470s BC, it bears an innovation: the serpentine figure of a Ketos, or sea-serpent, in the obverse exergue. Perhaps the emblem of the ruling oligarchy, the Ketos would feature on Syracusan tetradrachms for roughly the next 30 years.
