Galileo and the four moons of Jupiter
the first moon
bearing the fatal cup
the second moon
around a different god.
the priest and people sang
to a universe no longer listening,
the fourth moon
he knew what had enthralled a continent
was not worth dying for.
Galileo's telescopic observations of the major moons of Jupiter in 1610 confirmed that the rest of the universe did not revolve around the Earth or the Sun, undermining the prevalent contemporary religious dogma. The commentary here plays on the names Galileo gave them from Greek mythology: Ganymede was a cupbearer for the gods on Olympus and Callisto a nymph who entranced Zeus with her dancing; Io was another nymph seduced by Zeus, but the play here is on a line from the Christmas carol Ding Dong Merrily On High, and Europa was also (seemingly inevitably) seduced by Zeus and gave her name to the continent.
