Child of a day, thou knowest not
The tears that overflow thy urn,
The gushing eyes that read thy lot,
Nor, if thou knewest, couldst return!

And why the wish! the pure and blest
Watch like thy mother o'er thy sleep.
O peaceful night! O envied rest!
Thou wilt not ever see her weep.

Walter Savage Landor
