Did Galileo Mistake Saturn's Rings for Jupiter's Moons?

The blogpost discusses Galileo's potential mistakes in observing celestial bodies, suggesting he might have confused Saturn's rings with Jupiter's moons. However, the author questions the accuracy of this claim, noting that Galileo's sketches of Jupiter's moons show distinct objects, which contradicts the idea of him mistaking Saturn's rings for Jupiter's moons. The blogpost references a book by Ladyman, which claims Galileo mistook Saturn's rings for its moons, not Jupiter's. The author remains skeptical about the blogpost's overall reliability due to this questionable assertion.
