Page xlvii - Behind him cast. The broad circumference Hung on his shoulders like the moon, whose orb Through optic glass the Tuscan artist views At evening, from the top of Fesole, Or in Valdarno, to descry new lands, 290 Rivers or mountains in her spotty globe.
Page xxxi - Antarctic pole, the eternal sun strikes twelve at noon, and the glorious constellations, far up in the everlasting belfries of the skies, chime twelve at midnight; twelve for the pale student over his flickering lamp ; twelve amid the flaming wonders of Orion's belt, if he crosses the meridian at that fated hour ; twelve by the weary couch of languishing humanity ; twelve in the star-paved courts of the empyrean ; twelve for the heaving tides of the ocean ; twelve for the weary arm of labor; twelve...

Yes, noble Galileo, thou art right, E pur si muove.
