The Oxford Dictionary of Quotations Preface

Death and his brother Sleep!
One pale as yonder wan and hornéd moon,
With lips of lurid blue,
The other glowing like the vital morn,
When throned on ocean’s wave
It breathes over the world:
Yet both so passing strange and wonderful!
‘The Daemon of the World’ part 1, l. 1 (a revision of the opening lines of ‘Queen Mab’)
I never was attached to that great sect,
Whose doctrine is that each one should select
Out of the crowd a mistress or a friend,
And all the rest, though fair and wise, commend
To cold oblivion.
‘Epipsychidion’ (1821) l. 149
The beaten road
Which those poor slaves with weary footsteps tread,
Who travel to their home among the dead
By the broad highway of the world, and so
With one chained friend, perhaps a jealous foe,
The dreariest and the longest journey go.
‘Epipsychidion’ (1821) l. 154
I pant, I sink, I tremble, I expire!
‘Epipsychidion’ (1821) l. 591
Chameleons feed on light and air:
Poets’ food is love and fame.
‘An Exhortation’
Good-night? ah! no; the hour is ill
Which severs those it should unite;
Let us remain together still,
Then it will be good night.
‘Good Night’
Let there be light! said Liberty,
And like sunrise from the sea,
Athens arose!
‘Hellas’ (1822) l. 682
The world’s great age begins anew,
The golden years return,
The earth doth like a snake renew
Her winter weeds outworn;
Heaven smiles, and faiths and empires gleam,
