Hark! to the hurried question of despair:

"Where is my child?"—an echo answers, "Where?"

Lord Byron 1788-1824: The Bride of Abydos. Canto ii. Stanza 27.

I would applaud thee to the very echo,

That should applaud again.

William Shakespeare (1564-1616): Macbeth. Act v. Sc. 3.

'T was whisper'd in heaven, 't was mutter'd in hell,

And echo caught faintly the sound as it fell;

On the confines of earth 't was permitted to rest,

And the depths of the ocean its presence confess'd.

Catherine M. Fanshawe (1764-1834): Enigma. The letter H.

Ah, what a warning for a thoughtless man,

Could field or grove, could any spot of earth,

Show to his eye an image of the pangs

Which it hath witnessed,—render back an echo

Of the sad steps by which it hath been trod!

William Wordsworth (1770-1850): The Excursion. Book vi.

True ease in writing comes from art, not chance,

As those move easiest who have learn'd to dance.

'T is not enough no harshness gives offence,—

The sound must seem an echo to the sense.

Alexander Pope (1688-1744): Essay on Criticism. Part ii. Line 162.
