sidereus nuncius

For the heretical cosmology espoused in his March 1610 booklet, the above-titled Starry Messenger and later works, that unseated the Earth as the centre of the Universe, on this day in 1633, Galileo Galilei was found guilty by the Roman Inquisition and “vehemently suspect of heresy”—sentenced to indefinite house arrest. Forbidden from publishing any new material, the astronomer was further required to publicly recant, repudiate and denounce his opinions, though according to popular accounts whilst delivering his abjuration, Galileo rebelliously muttered Eppur si muove—and yet it moves, under his breath.
