Galileo proved Ptolemy wrong.

So, by the way, did Tycho Brahe.

Btw, in the process involving a discussion of the evidence, under St. Robert Bellarmine, no one was defending Ptolemy. St. Robert was defending Tycho Brahe.

Galilei did not prove the heliocentric world model nor refute Ptolemy. He just looked through the telescope and observed mountains on the moon and phases of Venus. This suggested that the planets and the moon are bodies and not only points of light. The discovery of the moons of Jupiter showed that there are bodies not circling around the earth (nor the sun). But this could also mean that the epicycles are real ….

The proof that the earth circles around the sun was given 1728 by William Bradley, the direct proof that the earth rotates was made by Léon Foucault 1851.

“This suggested that the planets and the moon are bodies and not only points of light.”

That was known to Ptolemy.

“The discovery of the moons of Jupiter showed that there are bodies not circling around the earth (nor the sun). But this could also mean that the epicycles are real”

In Ptolemy, an epicycle is around a void epicentre, it doesn’t have a body as an epicentre.

So, on this item, he proved Ptolemy wrong.

No proofs were ever given that Earth either orbits the Sun or rotates, both 1728 and 1851 allow other interpretations.
