Ganymede is one of the four moons (Io, Europa, and Callisto are the others) that Galileo observed in 1610 from a tower that has its double at the King Street Station. The discovery presented the first real crack on the earthcentric Ptolemaic universe. The cause of the crack, which eventually ruptured a massive body of human knowledge, was the realization that Jupiter and its moons could represent the organization of the whole solar system. After Galileo, it was not impossible to see earth's position in the order of the universe as more like one of those giant moons. This conception is one of the most important events (and events in the Badiou sense) in the history of the human form of consciousness.
