There's the evidence of the character Simplicio, who employed stock arguments in support of geocentricity, and was depicted in the book as being an intellectually inept fool.

The arguments made "by an idiot" were clear swipes at both Lodovico delle Colombe and Cesare Cremonini.

And other passages in other works of Galileo, but that alone is sufficiento sink "Evidence-free claim".

This has been batted back and forth since (at least) The Sleepwalkers (1959) by Arthur Koestler so you can argue against the assertaion but it's foolish to pretend there isn't reams of references on this going back decades.

That's not evidence. That's the claim. If you claim that he was put to death for making fun of someone, you can't prove that by claiming that he made fun of someone. It's total conspiracy theory stuff.

All those references are in the class of this salt stuff in the OP. They're whole fiction.
