This is the story of the meteor that changed the world forever. In 312 AD the Roman Emperor Constantine claimed he saw a mysterious light in the sky which convinced him to convert to Christianity, forever altering the course of history. Now scientists believe they may have tracked down the source of this mysterious light. A team of geologists have identified a crater in Italy which they believe was produced by the impact of a previously unrecorded meteorite. The finding could explain not only the story of Constantine, but might also provide an explanation for a local legend which recounts how members of a pagan cult were overwhelmed by a light in the sky as bright as a second sun. The cult too immediately converted to Christianity. A team of international experts set out to get to the bottom of the mystery.
