I appreciate the correction and amplifications. Archimedes was killed by a soldier of Marcellus, not Sulla. For me the central problem of the Index was not so much its secular effects (though it is easier to find those than you say; the secular prohibition on teaching Descartes, for example) but that by its nature it proclaimed that ignorance was a moral virtue.
