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 88 - Go, wondrous creature! mount where Science guides, Go, measure earth, weigh air, and state the tides; Instruct the planets in what orbs to run, Correct old Time, and regulate the sun; Go, soar with Plato to th...

Strona 101 - As home he goes beneath the joyous moon. Ye that keep watch in heaven, as earth asleep Unconscious lies, effuse your mildest beams, Ye constellations, while your angels strike, Amid the spangled sky, the silver lyre.

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...
