Siderius nuncius (The Starry Messenger)

Another revolutionary publication, Galileo’s Sidereus nuncius (The Starry Messenger) is present in the Library in the form of a pirated edition printed in Frankfurt in 1610, copied from the first edition published that year in Venice. In this modest-looking pamphlet Galileo published the astounding observations he had made using the telescope: the uneven surface of the moon, sunspots, the moons of Jupiter. It is bound with a number of related works, including Johann Kepler’s Dissertation on Sidereus nuncius, published the following year.
