Strona 195 - 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.
Strona 36 - 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.
Strona 69 - Then stay'd the fervid wheels, and in his hand He took the golden compasses, prepared In God's eternal store, to circumscribe This universe, and all created things: One foot he centred, and the other turn'd Round through the vast profundity obscure, And said, ' Thus far extend, thus far thy bounds, This be thy just circumference, O world!
Strona 381 - O how canst thou renounce the boundless store Of charms which Nature to her votary yields ! The warbling woodland, the resounding shore, The pomp of groves, and garniture of fields ; All that the genial ray of morning gilds, And all that echoes to the song of even, All that the mountain's sheltering bosom shields, And all the dread magnificence of Heaven, O how canst thou renounce, and hope to be forgiven ! These charms shall work thy soul's eternal health, And love, and gentleness, and joy impart.
Strona 235 - Fairest of stars, last in the train of night, If better thou belong not to the dawn, Sure pledge of day, that crown'st the smiling morn With thy bright circlet, praise Him in thy sphere, While day arises, that sweet hour of prime.
Strona 181 - As when the moon, refulgent lamp of night, O'er Heaven's clear azure spreads her sacred light, When not a breath disturbs the deep serene, And not a cloud o'ercasts the solemn scene ; Around her throne the vivid planets roll, And stars unnumber'd gild the glowing pole, O'er the dark trees a yellower verdure shed, And tip with silver every mountain's head...
Strona 381 - IX. 0 how canst thou renounce the boundless store Of charms which Nature to her votary yields! The warbling woodland, the resounding shore, The pomp of groves, and garniture of fields; All that the genial ray of morning gilds, And all that echoes to the song of even, All that the mountain's sheltering bosom shields, And all the dread magnificence of heaven, O how canst thou renounce, and hope to be forgiven ! X.
Strona 365 - And fated to survive the transient Sun ! By mortals and immortals seen with awe ! A starry crown thy raven brow adorns, An azure zone thy waist ; clouds, in heaven's loom Wrought through varieties of shape and shade, In ample folds of drapery divine, Thy flowing mantle form, and, heaven throughout, Voluminously pour thy pompous train...
Strona 291 - God of the rolling orbs above ! Thy name is written clearly bright In the warm day's unvarying blaze, Or evening's golden shower of light. For every fire that fronts the sun, And every spark that walks alone Around the utmost verge of heaven, Were kindled at thy burning throne.
Strona 310 - If you forgive me, I rejoice; if you are angry, I can bear it: the die is cast, the book is written ; to be read either now or by posterity, I care not which : it may well wait a century for a reader, as God has waited six thousand years for an observer.
