Էջ 58 - Or, if they list to try Conjecture, he his fabric of the Heavens Hath left to their disputes — perhaps to move His laughter at their quaint opinions wide Hereafter, when they come to model Heaven, And calculate the stars; how they will wield The mighty frame; how build, unbuild, contrive To save appearances; how gird the Sphere With Centric and Eccentric scribbled o'er, Cycle and Epicycle, orb in orb.
Էջ 289 - Or of the eternal co-eternal beam, May I express thee unblamed ? since God is light, And never but in unapproached light Dwelt from eternity, dwelt then in thee, Bright effluence of bright essence increate. Or hear'st thou rather pure ethereal stream, Whose fountain who shall tell?
Էջ 332 - 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.
Էջ 382 - Less than archangel ruined, and the excess Of glory obscured ; as when the sun, new risen, Looks through the horizontal misty air Shorn of his beams, or from behind the moon, In dim eclipse, disastrous twilight sheds On half the nations, and with fear of change Perplexes monarchs.
Էջ 294 - Horrid with frost and turbulent with storm, Blows autumn, and his golden fruits, away : Then melts into the spring : soft spring, with breath Favonian, from warm chambers of the south, Recalls the first.
Էջ 289 - Or hear'st thou rather pure ethereal stream, Whose fountain who shall tell? Before the sun, Before the heavens thou wert, and at the voice Of God, as with a mantle didst invest The rising world of waters dark and deep, Won from the void and formless infinite.
Էջ 289 - His mirror, with full face borrowing her light From him, for other light she needed none In that...
Էջ 401 - This Being governs all things, not as the Soul of the World, but as Lord over all; and, on account of his dominion, he is wont to be called Lord God, or Universal Ruler.
Էջ 400 - This most beautiful System of the Sun, Planets, and Comets, could only proceed from the counsel and dominion of an intelligent and powerful Being.
Էջ 76 - Works in the secret deep; shoots, steaming, thence The fair profusion that o'erspreads the Spring: Flings from the sun direct the flaming day; Feeds every creature ; hurls the tempest forth ; And, as on earth this grateful change revolves, With transport touches all the springs of life.
