Side 164 - He scarce had ceased, when the superior fiend Was moving toward the shore: his ponderous shield, Ethereal temper, massy, large, and round, 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, Rivers, or mountains, in her spotty globe.
Side 153 - I will indulge in my sacred fury ; I will triumph over mankind by the honest confession, that I have stolen the golden vases of the Egyptians*, to build up a tabernacle for my God far away from the confines of Egypt.

Side 177 - One forms however," says Playfair, " a very imperfect idea of this philosopher from considering the discoveries and inventions, numerous and splendid as they are, of which he was the undisputed author. It is by following his reasonings, and by pursuing the train of his thoughts, in his own elegant, though somewhat diffuse exposition of them, that we become acquainted with the fertility of his genius, with the sagacity, penetration, and comprehensiveness of his mind.
