When Worlds, that count his Circles now, unhing’d,(Fate the loud Signal sounding) headlong rushTo timeless Night and Chaos, whence they rose.

The lamp of day is quench’d beneath the deep,And soft approach the balmy hours of sleep:Nor fits it to prolong the heav’nly feastTimeless, indecent, but retire to rest.
