Very well  alone! Beginning to clean up this very large drive-by edit (check the editor's contrib list, indexed above). As a preliminary, cleaning up the prologue, which has been inaccurate for yers: no one has presented a shred of evidence that Tycho was already replacing Ptolemy among the Jesuit astronomers by the time Galileo started drawing fire. It's often asserted, but never supported. Surely Clavius never advocated Tycho. Fantoli says, in a book translated by a Jesuit, that the change came later, when (and because) Galileo got in trouble.
